[@waynemartineau4289]

Should take off the cover and check for gas leaks inside the unit, the manufacturers work needs to be field checked and twisting on water tank gas connection without a proper hold wrench can twist the connections inside the tankless unit and cause leaks. When tightening fittings in close areas always use two wrenches.

[@IceBerg2k]

Love the title of the video, Would be amazed to see you install a water heater in a non-existing home.

[@RidgePowerEquipment]

It's a retro-fit install, versus a new build home which is very different - hence the title.

[@josephclegg895]

Im a licensed master plumber and trained by rinnai us as a level 4 tech. I can tell you number 1 the gas line is undersized. Unless you installed the lowest btu possible unit your probably running 150,000btu min. You should be running a 1” gas line from the meter to the tankless directly depending on the length an material it could be larger. Second the flue although spaced properly which is good unfortunately it’s in an inside corner which will cause the exhaust to periodically be sucked into the intake which is bad news for the burn chamber.

[@jeffreyjohn2037]

And the gas meter is too small.

@@tomhill9027 This install would never pass inspection in Colorado or not in my county anyways. The issues you mentioned plus a couple more. Rinnai and Rheem both teach a very different setup and installation that would meet code. I usually do not comment but that install would make me nervous. The homeowner can pull a permit personally, but that would fail instantly with about six violations or unacceptable items. I guess as long as it works and nobody gets hurt.

Any reason you didn't hang the water heater nearer to the vent exit? I find the small pressure lines (incl gas) easier to run and they take less space than running the vent lines to the other side of the room.

[@user-kd4xl2dq1c]

I have never had a tankless, have had water heaters installed myself pretty easy (last one cost me $600) lasted about 10-15 years little maintenance. Tankless DYI like this guy if not you probably need to get some pro to install $3k to $6k. 1 )Biggest selling point of tankless used to be instant hot water (I was always skeptical-how!?) now it comes to light that that is bogus... 2) Also big energy cost savings $8 a month = that will take 50 years to pay for itself. Total no brainer for me (my opinion vast majority of people) tank water heater until tankless gets way way cheaper which doesn't seem to be anytime soon.

[@carlreichelt8724]

Well tony d..would like to go see u buy a tank heater now for 600 bucks u would end up with a 40 gallon cheapy from manards that would only last u prolly 8 years if u lucky & that would be no where as efficient..and yes if the unit is hooked up properly & every thing is sized accordingly or unit is not undersized u will get hot water to the fixture very quickly..far as only saving 8 bucks a month on cost to run I would say that's a little off as well.. considering the tankless does not need to hold water and continuously heat it as a tank type does or take the amount of time the tank type does to get u up and running to have hot water again after your teenager drains it with half hour showers or more..also most likely depending on what u would need to keep up with your use load u would only spend around $1500 for a quality brand tankless not 3 to 6k..well add around 3 hundred bucks or so for the material still way under plus u do your own like u said so save ton on labor too right..

My wife and I occasionally stay at a friends guest house which is above a garage. The tankless unit id directly below the barh faucet? Maybe 6 ft of run. It takes 42 seconds to get hot water. And whenntaking a shower if anyone turns on another faucet you know it by the temo drop. And do not turn off the shower to soap up or the cold water sandwitch will give you a rude awakening.

[@johnnyb8629]

done this many times when I worked in residential. There are a few things people need to consider before switching to one of these, first, if your house is still plumbed in old galvanized pipe forget getting a tankless unless your going to rip it all out and replumb in copper. secondly you need to have the right size gas line available and the BTUH available to run the tankless. I have seen on some small houses with small meters that have multiple gas burning appliances run out of gas cfm running multiple appliances while trying to run the tankless. I personally run both the intake and exhaust at the same angle just for the symmetry of railroad tracking the lines but to each their own.

[@jeffhuntley2921]

Johnny B. What about galvanized pipe doesn’t work with a tankless heater? I mostly switched to pex but some of my hidden piping I left alone

[@johnnyb8629]

@@jeffhuntley2921 The problem with galvanized pipe is that it rusts closed and restricts the water flow. Tankless water heaters heat large volumes of water with high delta T in short amount of time, water flow is important. If it works at all, it will only cause premature failure of the heater over time and unsatisfactory performance.

I not sure but in California we use copper from water heater up the wall exposed mount to the ceiling and from the ceiling we use Brass Adapters to pex and ur missing insulation on the line

[@GeorgeWitham-qb6ye]

This was an exact replacement for the old one that lasted about 10 years. kzbin.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh 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).

First question is, I thought you cannot run pex directly to your hot water heater? Second question is did you have to terminate any electrical for the tankless? I did a couple jobs before where I had to wire up the tankless heater. If i remember correctly, I believe it was due to them wanting to tie it in to their smart home system. Tekmar if I remember correctly.

[@Balticblue93]

Normally, you need 18" of approved piping away from the unit before switching to PEX. The Rheem and Rinnai models I have installed plugged directly into a standard outlet as it is only used for powering the electronics. I haven't done any systems that connect to a smart home system. Do you have a link of what type of system that was?

[@JuanWonOne]

Hey Marshall, you mentioned it was a family member you did the work for, and keeping costs down is pretty important. I dont know your background but I do have a couple of questions if you wouldn't mind answering. 1) why use pex over copper for the cold supply and hot supply? You secured the 2"x4" to the wall. Why not just use bell hangers to secure the piping to the to a 2"x 6" instead? I also noticed that you've used shark bite valves, I've had terrible luck with those on huge temperature swings. 2) do they not require a condensate neutralizer where you live? We do up in Canada. The condensate is very acidic and eats out old underground piping unless it's the very old clay tile. Great video otherwise 👍

[@PTSDwithME]

1. pex is resistant to corrosion and acidity more than copper is, I agree SharkBite's are garbage and not even allowed at most professional plumbing outfits 2. most residential codes do not require a neutralizer kit below a certain BTU value

Mike, any ideas about this 👇 For anyone watching this, what kind of hangers and brackets can be used to secure the iron gas pipe ?

Quick question on this install... noticed the meter was 250 CFH. Did you have the gas company upgrade it after this install? NG furnace, NG stove, and now NG tankless must be over? The reason I ask is because I have same size meter and plumbers are looking at me like I got 10 heads when I ask them don't I need to upgrade the meter first.

[@Balticblue93]

That is just one of the half dozen or more items that would never pass inspection.

[@carlreichelt8724]

That is prolly because your meter is good up to 250,000 btu's of output..your tankless is anywhere from 140 to 150,000 btu's for your furnace let's go high and say 100 to 120k btu's doubtful but let's go there..your dryer 25 k & your stove anywhere from 40k btu's to run 2 burners full blast and the oven all at same time..giving or taking on this figures you should be fine..most important thing is the piping if that's not sized right then you could run into problems it all starts at the header pipe that enters the house that is supplying all the rest of your branches that pipe needs to accommodate the supply of BTUs for your entire house when you add them all up all by itself..then size down from there

[@spencerl4004]

A 250 meter (size) can supply well over 250 cubic feet of gas during high demand times. On a 7" system which is what this is, your going to have 300k+ BTUs available per hour. Makes sure all your piping is sized correctly. That's the main concern. It's not uncommon for me to see a 4 unit apartment running on this same pressure ( w/ a Schaumburg reg).. 4 furnaces 4 tank water heaters.

Tremendous video, one question, I can do all of that, I'm a plumber, but they tell me that they have to be someone with a license, when the inspection arrives, they will have a problem for me, which is true ?

[@tibet1976]

Nice video. Easy to follow. One question, what is the reason for having two valves on both the hot and cold? If you already have the valve kit that screws directly to the heater, why put yet another set before/after?

[@jj6457]

Just for whatever in case you need to remove the hot water heater maybe to a different location. Other then that there’s really no purpose.

I have learned to never use dish soap for checking gas leaks. It is a degreaser which will remove some pipe sealants and is corrosive and can rust steel pipe.

[@andywahl9631]

Only use approved gas leak solution

I have a tankless water heater in a tiny house in the mountains that is powered by a generator…I have winterized in the past with antifreeze but heard these units have freeze protection! Can you provide any recommendations?

Tankless is awesome. Had mine for 6 years no complaints. Annual servicing but that's it. Good investment.

I am planning on removing my water heater and put tankless water heater. My current water heater is using PvC for vent. And it goes up in the attic to the roof. So my question is can I use my vent That I currently have on my tankless water heater? It about 20 to 30 going up? Pvc

Did good but that wood framing is def not as sturdy as anchoring it to that block wall . It’s hollow but it will hold better then floating 2x4 .
