Dude he’s a Professor of Commercial Mechanical Cleaning apparatuses. This video opened my eyes on the concepts of how these machines function. I’m holding he can take apart and explain the concepts and overall functions for maintaining the engine itself this way in a future video. That would also be bad ass! Thanks Ben. These videos really do rock.
Very informative video. For clarity, the water is drawn in through the lower check valves when the pistons retract. That water is now in the chamber between the upper and lower check valves. When the pistons extends or on their compression stroke, the water in the chambers is then forced out through the upper check valves under pressure to the wand. This is my understanding of your very informative video. Thank you
What causes unloader to pop frequently? My machine came with 4gpm triplex pump which is similar to that. I installed a soft unloader; the type that has a delay and it was fine for a bit then started doing it again, unloader cycled often.
@@timothyblaze4556 On the oil side of the pump, there are seals that the pistons go through and if those seals are bad, water can get in the oil that way. Also there is the oil fill cap on the pump, if that’s faulty water can get in. There’s an oil seal around the drive shaft too coming off of the engine. Those are the 3 main places where water could be getting in.
Great video, to add a question to this, not only do I have water in the oil, but I also see the pump leaking oil where the head meets the pump, I assume this is the same cause, bad oil seals?
Awsome explanation but I have a question why won't these pumps pull water from a water tank to feed the pump unless the pump is primed once the pump is primed the pressure washer will continue to pull water from my tank even if I don't use my pressure washer for days , I'm thinking for example if I unhook the water supply for any reason and air gets in the pump the pump lost its prime and when I hook back up the water supply start the pressure washer my pump will not pull water through it unless I prime it. Are all P/W like that?
Good question, they will prime but if there is even a tiny air leak, even big triplex pumps will fail to prime. Check your bypass line that goes back yo your tank. If it’s dumping water back into the tank, right over the tank fitting at the bottom air bubbles from the by pass will get into the intake and simulate an air leak…
Hi, I have honda gx390 with ws202 interpump and gear box, Engine seems to be running as it should but I noticed a drop on pressure at tip , I gave full service nee unloader valve, still down on pressure, working but down pressure id say 40 / 50%, Any suggestions greatly appreciated.
Hey Giant, Yes I can actually do you one better. Soon I'll be doing a video on washed out pump heads, and as you mentioned packing and seal kit installs/rebuilds... so ya, coming in about a month or so...
@@benshrope5707 Im looking at new check valves for my 8 gpm pressure pro on pressure teks website and they have two options, option 1 the kit is 62 bucks for 6 check valves and rings, option 2 there 192 bucks for 6 checks valves and rings. Any idea that the difference would be? The dont explain on the website.
Hopefully you'll see this request. I have a pump just like the one you are demonstrating evidently it had a foil tag on it but it's missing only number I can see on the pump is a 405 that's what I need to know what make pump that is and model.
One or two things can lead a chronic repeat of this issue: assuming the oring is sized properly, if the plug is not screwed all the way down, this causes the check valve to not be held in tightly and securely, and it will sort of rattle around inside a little or alot which will cause the oring to be loose and get flushed out through the system, or come apart in little pieces and get flushed out. If then the machine is not repaired soon and the oring replaced quickly, the check valve’s metal base will bang on the brass oring seat and start chipping away little pieces of metal where the oring normally sits and provides a cushion and seal. If the check valve has, as a result of moving around, has chipped away at the check valve seating surface it will blow O-rings out constantly because there is no longer a smooth machined valve seat surface. Junk the pump head or take to a machinist who can build up the damaged valve seat and then machine it back down to spec.
Why would I keep finding pumps that refuse to pass water? They don't allow water to come out of the outlet. I can get water out of every single orifice but the high pressure outlet hose hookup. Thank you
within the internals of the pump, the only object in the pathways from the low pressure intake, to the high pressure outlet of these types of pumps is the check valves, which force water to move in only one direction. pull these out and inspect to see if every single one of them is fused shut or something (which they won't be) I suspect you have a different problem and that is, somewhere along the intake plumbing you have a leak, and the pump is getting air into the intake line. When you have an air leak the pumps usually fail to prime and run really rough due to the cavitation. Check to see if the pump is sucking air, and if no leaks, prime all air out of lines then start the machine up...
@@PolyVshot brother I kid you not I opened every orifice and get flow from it except the outlet. I even made sure the valves worked, and they did. There is something to these pressure washer pumps other than the valves. I'm figuring this out today. I have three almost identical pumps to work with
Dude, this is the best damn explanation of how these pump works! Awesome video, thanks.
Could you do a video on unloaders?

Thanks for the amazing video. Quick question my pump is getting water into my oil case how could that be happening? Thank you!

Is there a system or switch on that specific pump to stop the pistons from building too much pressure inside the pump ?
@@aaabbb4353 no that function is handled by a separate part called an “unloader valve”.
@@PolyVshot Ok. And it wld be fixed on the pump, along with the manometer, around the high pressure out and disengage the engine ?
Can you do a video on an 8 gpm showing the packing rebuild? Please.

Mines loosing pump oil where you said the water would come out underneath if the seal was bad.
Ya, if oil is leaving the crank case, those seals that wrap around the ceramic pistons need replacing…
@@benshrope5707 where can I find them for a tss1021. 4.8gpm

What can cause when a check valve o ring gets sucked in? What can be the reason for to do that?
