Not only does it quiet the pump, it extends the life of the water pump :)
If the problem was the pump noise while you’re in bed, maybe moving the pump out from *under the bed* would be a better long-term solution - especially when Shurflo’s own installation guidelines say to install it away from living quarters yet your RV manufacturer thought under the bed was best. 🤦🏻♀️ Regardless, thanks for the video. I learned how to pressurize mine. I appreciate it. 😊👍🏼
On that thin paneling, I've successfully put a thicker backer board (1/2" piece of pine or plywood) behind it and then screwed the device on through the paneling into that backer board. Works quite nicely and opens up more options for where I can mount items.
I have a Shurflo 4008 series in a new Thor Chateau motorhome. It had very annoying hammering or chattering which I found was caused by an improperly adjusted pump pressure switch.
When you turn on a faucet the line pressure drops, causing the diaphragm in the pressure switch ("on-demand" feature) to activate the switch - turning on the pump. When the pressure builds, the switch turns the pump off. There is a small allen screw on the end of the pump for this adjustment. I turned the water on to a trickle to make it "chatter". As the water was running, I slowly turned the screw to the right until it stopped. I tried different volumes of water through the faucet and made small adjustments as necessary. BINGO - no more chattering!
My next step is going to be quieting the motor - the pool noodle sounds intriguing.
If this is successful, I'm not sure the accumulator - basically a very small pressure tank - would make any difference for me. It's not really large enough to store enough water to prevent pump cycling in a meaningful way. Even with the accumulator installed in the video, the pump still cycles maybe every 3 - 5 seconds or so. My plan is, since I've solved the chattering, to focus on sound isolation/deadening. As long as the flow at the faucet is steady and I can't hear the pump, the pump cycling is immaterial.
In summary, I think some brands of pumps are just better designed than others. The Shurflo line seems to get good reviews.
Download the manual (PDF) from the Pentair website. It explains some of the causes of the chattering and quick cycling, and how to solve them.
Agree adding a second flexible hose to the other side of the pump and putting some sort of flexible McGyvered dampening pad/gasket between the pump and the floor where it’s attached could isolate more of the pump vibration... I would also look to relocate it from under the bed!
My 2019 Radiance came with this from the factory. Pump is very quite and the it cycles much less. Fun fact, if you have the pump off and you stop at a rest stop, you can do a flush and quick hand wash without turning on the pump. The accumulator has enough pressure to give you water for a short period of time
I believe the accumulator tank pressure should be about 3 psi below the water pumps cut in pressure for optimal performance.
I bought the same accumulator tank and the included instructions from the manufacturer states that “The most efficient use of the accumulator occurs with the pre-charge set at the SAME pressure as the pressure switch “turn on” setting.”
How do you find out the cut in cut out psi I’m really struggling to find this out my pump is a camplux 6lt 65 psi
GREAT video and I'm pleased to see how easy it is to install, since I just bought one and am planning on installing this weekend. Got mine to even the flow - knew it would quiet the pump (much), but glad to see it does a LITTLE bit. This is a *VERY* well made video and hit *ALL* of the high points - even maintenance and pressurizing. Again - GREAT JOB!! Thanks for your time!
+Weylan Bryant thanks for watching and the great feedback! We really appreciate it!
It also stated on the box that it will help eliminate high pressure water spikes. which is the reason I ended up mounting 3 of them. fixed my pressure spikes. brought my 100+ psi spikes down to around 65. never did check the pump after the install, not going to worry about it now, it's almost 0200 hrs. i did this back in 2019 I think. just happened to see this video right now and thinking i may have seen it before. if so, all good. Good Luck & Safe Travels.
Now we replace the water pump in every RV we own with the bigger aqua jet 55a and love it
I have seen lots of installs in rvs, but your install makes the project look real easy.....
+Mark Cole thanks! I tried to keep it simple, of course different trailers pose different challenges though.
Great video. Thanks for uploading. Another aspect you didn't take into account is water expansion which this also deals with.
I burnt out the microswitch in my pump due to the on off chugging. Definitely worth fitting an accumulator tank
In our current trailer we replaced/upgraded the pump right if the bat. An aquajet 55A. Well worth the upgrade!
www.amazon.com/Remco-55-AQUAJET-Industries-55AQUAJET-ARV-Aqua/dp/B004RCSLFS
Those switches are easily replaced
Go to tractor supply. Get a 1" rubber mat. Place the mat between the floor and the pump. It'll help keep the pump vibration from going directly to and trough the floor
I used a rubber floor mat from home depot. It’s has the same corrugated look . Works and looks great. It took about a quarter of the sound away.
I have a water filter system attached and maybe that's why I didn't have the degree of water pressure inconsistencies. However, they never properly install any of these water pumps. Every manufacturer seem to just dangle it wherever. I used 1/2 plywood to create a new mount under my bed and it reduced the noise by 50%. I hard mounted the filter and pump to plywood and screwed that into flooring. . The pump usually have soft mount points and provided they're installed correctly, they dampen the vibes.
Thanks Mike. I am still in debate on this. Appreciate your efforts.
If anything upgrade the entire water pump to a variable one. Much better and quieter
I saw another guy put foam tubing around the pipes either side of the pump, made it utterly silent for a few bucks.
That's exactly what I want it for is smoothing out the flow (the chugging) Again Great job! Thank you!
+Edward Young thanks! It works better than I expected out of it, easy to install as well!
Mount the pump on rubber to help reduce noise transfer to the wood. The open area under the bed amplifies the sound, like the hollow body of a guitar. Adding a panel of light weight acoustic drop in ceiling tile may absorb sound too.
I have to disagree with your comments at the end of the video. I went back and watched the first 20 seconds of the video again. There is an incredible amount of difference in how the water exits the faucet! The water mixed with air bubbles and spits and vibrates and is loud. Then at the end of the video you have completely eliminated that nonsense. Now all you need to do is wrap the water lines with some foam tubing to eliminate the sound emanating from the area around the pump. I have done all of this in my travel trailer and I no longer hear the pump when it’s running and the water flows perfectly. Was it worth $60 plus an hour of my time? Darn right it was!
Cheers mate and happy trails
The factory couldn't have found a worse spot for the water pump. Wow.. I think you could have put a loop in that new line. Just a thought.
Great video. Nailed it. If your RV doesn't have an accumulator tank, then you're just roughing it.
+Michael Maes haha it made a noticeable improvement. Thanks for watching!
Those stainless lines are great
Thanks!
Wow! Under the bed! Crazy place for a water pump. Of course I have a Class A so my water is on a shelf in a basement compartment. Even there I can hear it pretty loudly when you turn on the bathroom faucets.
I would like to install some rubber pads under the feet that I have been carrying around for a few years.
Also just saw a video about using the foam pipe wrap to quiet it down and that seems to work. I would also try that.
I had a 2009 Fleetwood Tioga Class C and the water pump was under the fold down split bench seat. Try holding the seat and change the water pump out!! You really have no room to get under the seat, hold the seat up and do the work. Now I have 2018 Keystone Outback 266RB and the pump is located behind a small panel in my luggage compartment, Plenty of room and easy to get to. One reason I got this trailer, I have only two factors when purchasing a travel trailer, LARGE bathroom as my 266RB is and ease of access to the water pump. Other than that, that is all I need.
Maybe line out the area around the pump with some carpet to reduce noise within that area. The sound of the pump is bouncing around that area, off the hard walls, which is a bit like a speaker box
Thank you so much for the hose tip. I did just what you said and it worked out perfect for me.
Glad to help!
Nice info and install! You might try replacing the pump with a variable speed pump… I hear they’re a lot quieter and smoother (plus you can just keep the old pump so you have a spare)!
We now replace the pumps in all our RVs with an aquajet 55a pump. We've had several RVs since this video haha👍 thanks!
@@WanderingWagners -So do you also use an accumulator with these higher end pumps? I just bought a 2006 View (mini C) and I think it is the 18 yo original pump. Yes, not very impressive. I looked through your video titles, saw a bunch of RV changes, but I didnt see anything specific in the titles about doing this.
Some pumps recommend that you don't use accumulator tanks. Just depends on the manufacturer.
Great instructions, thanks.
You're welcome
replace the water pump and or put some kind of foam under your water pump..
I already bought an Accumulator, and then found your video. Awesome walk-through, thanks! Can't wait to try it for ourselves. :)
+CasaRocinante thanks! It's easy to install and worth the cost/time. Good luck!
Surflow pumps have a bypass adjustment too I think it's 9 turns pressure is 12 turns but yea a accumulator tank helps a lot
I'm inspired.. Been wanting to do that for quite a while.. Thanks
+RVdaydream And I watched your video on the vortex fan install and now I want one!
I don’t need one,but I want one
Great instructional video! Thank you!! Gonna get one!
+Edward Young we really like having it now, really smoothed out the water flow.
I use a 2 gallon reverse osmosis accumulator tank for my camper van
Top job man well done 👏
Thank you! 👍🏻
Thank you very much
Have to experimented with a lower air pressure as from my research the air pressure should be set at 3 to 4 psi below the cut IN pressure of the pump. This will maximise the available surge capacity and reduce cycling of the pump and therefore hopefully reduce noise further.
Thanks for the info
Mike, my only concern is the volume of water that stainless sink supply line can move. It is likely a 1/4 supply line where the PEX is 1/2 inch. Now that it's several years down the road and I know you've moved on to at least one more RV did you notice any difference is the water flow?
Honestly there wasn't a noticable different in the volume of water.
Doesn't affect my flow rates
I’m surprised you didnt have amazon affiliate link
Thanks for the video, i hate the pulsing when using low water flow
You can use the any of our links and then search for it on Amazon
I have to get that hat! I am an IH guy!
Mount a good piece of foam rubber between pump and floor to silence the pump noise. The noise is vibration reverberating through any solid surface the pump is in direct contact with. If you think the hoses connected to water pump may vibrate because they are touching a solid material like wood put foam rubber behind the hose also.
+William Watterson thanks for the tips!
I am new to RVs, i get the sense that manufactures just throw these units together without any concern for the buyer. The water pump install is just another example along with poor quality materials and unskilled labor used to assemble these trailers. I did look for a quality trailer but the bar is set so low by the RV trailers manufacturing association that it didn’t seem to matter who was in the top 5. These videos that you guys put on U Tube are a great help to us owners, keep posting all of you. PS, my unit is a 2011 Keystone Springdale 28’.
Great job.
+John Shipley thank you! Thanks for watching
THe SS line is the way to go. I have seen the regular plastic ones fail.
they are all plastic on the inside
yes but the SS ones have a steel jacket oround the outside to hold the pressure. They will not just burst and ruin your day.
These electric pumps are cooled by the water flowing through them. Could placing a pillow or some type of insulation over the pump dampen the pump noise without causing the pump to overheat? I've also seen rubber shock mounts installed as feet where the pump is mounted to eliminate vibration from the deck board it is bouncing on.
The reason for the accumulator tank is to preserve the life of the pump. That bouncing back and forth that you had before with the water pressure especially when you turn the pressure down the pump doesn't know how to respond appropriately so the accumulator bags moves out the flow of water and stops the pump from turning on and turning off too quickly it saves the life of the pressure switch inside of the pump. Having one as well worth it it extends the life of your pump
FYI if you wear out your pressure switch on a shurflo water pump just remove it 3 screws on 4009 or 4 screws on older model , pry it apart. (insert a tiny flat blade jewlers Screwdriver into the small holes and release the clips) the microswitch just pops out its a v-15-2c26-k they are only a couple of dollars . It's a ten minute job to replace the microswitch and you don't have to replace the pump. Don't pay for a replacement pump or replacement pressure switch just replace the little micro switch .
Awesome. Thank you
+David McConnell very welcome!
Get yourself a box ( 100 ea) of pan head pocket screws washer style # 7 course 1.5". good for attaching anything to wood, and plenty of grip.
+Laurence thanks for the tip! 👍
I did the same thing that you did and found the same results. Noticed about 5 seconds before the pump kicked on. So the end result was 5 seconds of quiet.... lol
+classicbob44 it is still a little improvement and the water it much more smooth.
Try a 2 gal thermal expantion tank from hd.
More reserve for less than 40.00
Saves pump from running constantly
This one worked great while we had this RV
Great information....thanks...quick question do you think I could mount the tank on the floor next to pump...which means it will be flat on floor...I have very limited space to put it upright like you did..
Thanks
I'd say mount it where you have room. Trial and error might come into play but it should be ok
Thanks for this video! I did this exact install but for some reason it’s not working for me. I made sure to charge the accumulator to 30psi (my pump is 45) with h+c lines on faucet open and pump off. I then turned pump on and it just keeps going, and nothing comes out of sink. It’s as if the accumulator has fully blocked the flow- but in that case I’d expect the pressure to build up after the pump which should make it turn off, but it keeps pumping. I checked the pressure with multiple gauges. System was working perfectly before the addition of the accumulator. I added to reduce pump work and noise. I put the accumulator just after the pump. The only thing I could think my be the issue is that I have a check valve shortly after the accumulator, so maybe that affect pressure. The instructions do say to put accumulator before any check valves so it shouldn’t be an issue, but I’m not sure what else it could be. One thing I noticed is that the accumulator static pressure (pressure with pump off and sink valve open) drops from 30 to around 15 after a few mins after I turn on the pump. Maybe it’s just a bad accumulator. The pump is brand new so I know that’s not the issue. Any thoughts are greatly appreciated!! 🤷🏻♂️
I would check the valve and orings if there are any for cracks (depending on how you installed this) there may be air leaks. Run some soppy water on lines to see if there are leaks.
We didn't notice a chance in noise so much but it evened out the pump and the amount of had to run.
Great video! The accumulator has two attachment points to screw it to a wall and because of that it will always be 'wobbly'. Is there a reason? Any idea why they didnt add three or four attachment points?
No clue... Probably assumed it would be mounted on the floor?
Cover those water lines with pipe foam also
+Mike m Thanks for the tip! I'll try it out!
A simple way to make the pump much quieter... use a foam pool noodle! It's density and texture is perfect for deadening sound. Cut a piece one inch longer than the base of the pump. Split open one side of the noodle and force it out flat. Install it under the pump base. There is no need to remove any rubber gasket already under the pump base. You may need to use longer screws. When tightening the screws, compress the foam only enough to firm up the pump. The more you compress the foam the less effective it will be. The foam will completely eliminate the amplifying effect caused by the pump being directly mounted to the floor. Most types of rubber intended for this purpose are more dense and less effective.
It really wasn't loud but thanks👍
the real problem was that if the pump rapid cycles more than once every two seconds, the pressure switch will overheat and burn out.
+Wayne Wildman very good point!
Thats what happened to my pump.
Pressure switches don't overheat... They wear out. Motors overheat.
Every time switches break a motor circuit they experience an arc as the motor winding magnetic field collapses. This leaves carbon on the switch pads.
They will have a much shorter life due to use. Use them 10x a day vs 100x a day will effect their lives
Excelente video amigo!
Una pregunta, donde puedo conseguir ese tanque?
Yo tengo una bomba similar al tuyo
Thanks! I believe this is the tank but double check to make sure it'll fit your RV.
amzn.to/3WfYTfC
@@WanderingWagners muchas gracias amigo
Otra pregunta amigo, cuantos psi se le poner con una bomba que alcanza 70 psi?
5.5 GPM.
Espero que me apoyes amigo
Acabo de comprar uno , pero apenas tiene 15 psi. La verdad no tengo idea si esta bien así
I just picked up a 97' Jayco and it needs the water pump changed as well as it only builds air pressure, but doesn't push any water.
If I'm wrong, I'm willing to hear some suggestions to save some cash.
Check to make sure there isn't a low-point drain open somewhere or the pressure relief valve in the water heater could be open as well.
I tried to do a replacement water pump on your page and could not find it. Could you please advise what brand it was? I thought it may have been an Astro but can't remember. It was a smoother running pump. Thought you installed it in your Air Stream.
It was an aquajet 55
amzn.to/3qrsnKw
We also installed one in the Wraith!
@@WanderingWagners TUVM
@@sued115 very welcome!
Air pressure should be set to 2lbs less than the "Cut-in" pressure of the pump
.
I bought the same accumulator tank and the included instructions from the manufacturer states that “The most efficient use of the accumulator occurs with the pre-charge set at the SAME pressure as the pressure switch “turn on” setting.”
@@guitarman517.... If you do that, you will get a pressure dip at tank depletion just before the pump kicks on. Been there, done that. Try it you'll soon learn which you want.
Cho CoMo You may want to write the manufacturer to inform them that their included instructions are wrong and that you have a better opinion than theirs on how to setup their product?
@@guitarman517.... Yeah, I;ll get right on that....If my experience is of no value to you, thats fine. I know what worked right and what didn't. But you can shove your snide replies.
What we did worked for us
Did you install one of these in your Airstream too Mike?
Yep. Sure did.
Great video but the hose you bought was with FIP on both sides not compression on both sides. I spent a few hours going from store to store before someone figured out that was the case. Apparently getting a hose with compression fittings on both sides is not possible. So there you go... Got a hose with FIP on both sides at Lowes and 5 minutes later I was in business. Thanks for the video.
sounds like a submerged machine gun!!!
Kind of haha
What kind of pump do you have?
It was the stock shurflo pump
Awesome. I just installed one on my popup and what a huge difference. Water runs smooth and the pump is a tad quieter.
If your pump is anything like the Shurflo 4008 series, and it does seem to operate on the same principle, then your pump was/is badly in need of adjustment. Instruments can be used to adjust the bypass but trial and error works pretty well. My Sureflo, when adjusted properly, does not turn on/off rapidly ... or at all unless the water flow is reduced to not much more than a dribble. Mine only ever cycles at very low flow (a dribble) and then only when it needs adjustment. Nonetheless, I didn't like adjusting the Surflo twice a year so installed a two-gallon bladder surge tank. Now the pump typically runs only every third water use and the bypass adjustment is not nearly so critical. .......... In any event, if your pump is still cycling at all with moderate to higher water flow, its still in need of adjusted. Try adjusting the bypass first. It's too restrictive right now and needs to be opened a bit. You can do this with the water running or do it in increments until the pump no longer cycles.
