I love the amount of detail you give. I am in the process of installing a Rinnai Tankless. One day I am confident, the next, I am stressed out and filled with self-doubt. I calm down when I begin to watch this and other good UA-cam videos. I am taking it slow. Thank you.
Yes, but he completely avoids the energy source discussion. If he is truly an “off grid” installation, as his video title says, then his energy source is most likely propane (as a natural gas installation would indicate that he’s not truly “off grid”).
Great job. And thanks for the details on getting code right. If I were you, I'd mount a PEX manifold in that closet, alongside the water heater, and get rid of all that polybutylene pipe.
Thanks for making this video. There is a gas water heater in a room that I would like to turn into a bathroom so to create more space I plan on replacing it with a tankless unit.
I have found that if you hold the pex pipe it is possible to tighten the adapter into the fitting to prevent leak. I have even unthreaded so more pipe dope or Teflon tape can be applied.
Besides the one marked gas, which one is for the condensation line and do the tankless water heater require a overflow tray for water as a just in case like the trays on the old style tank water heaters? Where is the pressure valve and does it require a line that serve as an overflow for water vapor pressure buildup, venting it to the outside through the wall or into a drain pipe inside the wall which refinish? k
This was an exact replacement for the old one that lasted about 10 years. ua-cam.com/users/postUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).
Just an FYI while draining the tank, grab a 3/4" black iron with a shutoff valve connected to another 3/4" black iron you can use them to drain the tank much quicker and easier through gas valve or drain valve by removing them and putting the 3/4 pipe instead
Very nice video for DIY project.👏👏 I am planning to replace it very soon but it is confusing with the gas connection. I assumed your propane gas coming from the big house tank which has a first stage regulator and pressure could be about 10 PSI. But the most tankless water heater required less than 1/2 PSI. The following paragraph is coming from the manual "The new heater requires the Min 8.0"WC(1.99kPa)- Max 13.0" WC(3.23kPa=1/2 PSI). If the heater's gas supply pressure is greater than the specified maximum, a pressure regulator is required. The regulator must reduce the gas pressure to within acceptable limits' ' And my old 40-gallon water installed in the second gas regulator. Would you please explain how you did? Thanks in advance. John
It is correct that the second stage gas regulator for the old water heater is reduced from 10psi on the first stage of the regulator to 1/2 psi. I had a second stage regulator for an old 40 gallon water heater that I utilized for tankless water as seen in the video. Probably you have the same second stage regulator on an existing water heater that you can use for tankless water in my opinion.
Hello, may I ask what part of Colorado you are located? I have a farm in Eastern Colorado, near Limon that I want to do the exact same installation. Thanks, David
Great video, my only concern is that the electrical outlet is below the piping. If pipes leak or break at any point, water will run down the electrical cord and to the outlet. I'm not an electrician, so I don't know if that's a thing or not. Just pointing out the obvious worse-case scenario.
You need to get rid of all the grey poly and replace with pex, before it splits and flooded your house. Any grey plastic water line in any house throughout America, you need to get it replaced asap

So first im not sure why folks that dont really know what they are doing make these videos. Then in turn have the general public thinking they are pros and actually listening to and doing things wrong as well. Now for all the experts that keep trying to point out whats wrong. The most thing mentioned us sedinent trap on gas line lol. Which is code but a waste of time and pointless. But i find funny he says cant use that valve that came with it because its for black pipe so they got a brass coupling. Well that valve that came witt it is brass as well. Also that csst is hooked to black pipe under floor. Also they installed valve on hot and cold lines. Well if you shut cold vlave off, that in turn shuts the hot off also cause it is fed by that cold. So no valve needed on hot. Also he states they isntalled a valve under floor also. You should never install a hidden/non accesable valve. I guess they have no clue the purpose of that gas valve at the unit. Seeing how they mounted directly to the unit. It should have been mounted to rigid piping. Then a gas flex line between it and unit. So when you service the unit you can turn gas off at tge unit. Remove flex line and do what ever is needed. The way they did it, you are required to shut propane off to whole house making that valve pointless lol. Also no need to break the pex band, just unscrew fittting. It will swivel in the PEX. Sediment trap is required for NG or LPG. The propane tank does mot filter the propane lmao. Man the list goes on with whats wrong with this video but im tired of typing.
Not sure if i would put an electrical outlet below the heater in case of water leaks. Also, probably better to use sharkbites for pex fittings instead of crimp. They are easier to unhook if necessary plus they seal better.
Is the valve kit even necessary or required?? Seems you could just add a couple valves & pressure release separately for a lot cheaper. My budget is in the tank range & trying to make a tankless more affordable
Why so shy about telling us about the gas source? You say this is an “off grid” install. To me, that likely means there is NO natural gas availability. Please give us another video which discusses your propane (vs Natural Gas) supply to your Rennai Tankless Water Heater.

@TreadTheNet you must not have paid attention he talks about that early on in the video. Clean out those ears🎉😂
By far the best instant install explanation I've seen and the year after update was amazing! Thanks!
Great job. And thanks for the details on getting code right. If I were you, I'd mount a PEX manifold in that closet, alongside the water heater, and get rid of all that polybutylene pipe.
Agreed on that one, my neighbor came over and said oh boy that pipe bursts. Thanks for watching and have a great day:)

Where did you buy the clear plastic tubing for the p trap. Thanks
Good video, the "Gas leak detection solution" made me chuckle, just use soap and water in a spray bottle ;)
minute 21:57, when he was installing the O ring, looks like the bottom part was cut a little

Why did you have to ground the black pipe?? I don’t understand. Please explain. Also what happens i don’t ground it.
Very well explained and installed. Thank you.
I did not see the 500 degree hose link. Can you send it?
Your video is amazing. I've almost never seen DIY videos that can even compare. Thank you, and I subscribed too :)
Outstanding. Great work. Was thinking to use same old water heater exhaust.
Where did you get the vent kit from?. You’ll forgot to install sediment pipe for gas.

Alot your doing is very informative and can def use what youve done to my own application

where did you get the gas line fitting you were showing being installed?
He might have said it: but why didn't he tap into previous gas/Propane line,instead of running a new one?

Add a drip loop
23:30 I seen metal showing through on the gas line
Do you have to use the stainless vet pipping
Use a Thermel bypass Vale or crossover valve
This was great. My only question is whether I heard correctly that you’re brushing your teeth with hot water?
Disc golf bag in the background lol yes!
I follow your steps why I'm I getting code 11 ??
So I just watched another brand and they said that the vent piping is not a special pipe and is not expensive,
Nice job, thanks for sharing.
You also did not mention the continued maintenance needed in order for it to operate properly.
You mean the required maintenance you're supposed to do on any water heater whether tank or tankless? That maintenance that NO ONE does? Lol
You need to get rid of all the grey poly and replace with pex, before it splits and flooded your house.
Any grey plastic water line in any house throughout America, you need to get it replaced asap
The grey poly is garbage, theirs been lawsuits for decades
Clear instructions even though Dad did all the work😂
I appreciate the video bro!!!
why do you need drain, I thought it was a non-condensing unit.
Is a relief valve to drain water in case of emergency
@@DanielRojas-nw3mv the relief value is a safety mechanism. When the internal boiler pressure reaches an unsafe level, the water will shoot out from there. Without it, the whole boiler system could exploded technically
@@t-techvids9659 what I said ?
You’ll forgot to install sediment pipe for gas
He explained why he didn't. Popane tank filter.
You didn't actually watch the video did you....
If the piping is so expensive why not just go with a condenser model so you can use PVC?
Where is your drip leg “sediment trap”???
great job !

Thanks for watching:)
why didnt you add a drip leg to your gas
Just had to laugh near end of video my furnace is kicking on ... The exact moment mine kicked on lol.
thanks the way u explain u did it very well and i appreciate it good base u and take care
Thank you for watching:) have a great day
Ive seen plumbers use tape and put dope over the tape
Very cool
to make a short story long !
I have always wondered is what happens if you let the party stop I just keep clicking Chris videos so I don’t know 🤷
If you let the party stop then you loose your turn in line for the restroom:)
Not sure if i would put an electrical outlet below the heater in case of water leaks. Also, probably better to use sharkbites for pex fittings instead of crimp. They are easier to unhook if necessary plus they seal better.
Not sure any plumber should use shark bites. The way to go is copper
Today Chris gets himself into some real Hot water. Except episode
Maybe a Jacuzzi episode?
Is the valve kit even necessary or required?? Seems you could just add a couple valves & pressure release separately for a lot cheaper. My budget is in the tank range & trying to make a tankless more affordable
The valve kit is for descaling and maintenance if you skip that you’ll be replacing the unit sooner
Save few bucks during Installation, then when Maintenance needs done, plumber charges you way more than you saved to get them in to flush the unit
Not much of a "How To" video, more of a "let me show you what I did" video.
Do you lack common sense on how to apply what he's doing to your installation or just lack a brain
How many times can you say "here"...

You wouldn't have gotten that water leak if you would've used the right Teflon tape. Blue Teflon tape is for water not white.
why can't I have a plumbling background
Can't u be quiet like dad!? And man'scape clogged my sink!
Ruf? Or ROOOOOOF..lol
DUDE, YOUR OVER FOING IT BOOO
Never pipe dope female threads,
Only on male threads.
Your ruff.
Too much blah blah too little demonstration.
You talk too much!
What about a condensing one? Will the existing exhaust pipe for a tank be a problem?
