Don't forget to clean the combustion air screen and inlet water screen! Those buggers get dirty

The cold inlet screen too. There is a whole maintenance process I’ll do a video on soon. This was just the flushing.

Also a good thing to note youre supposed to flush the opposite way the water typically circulates through the system
only thing I would do different, is not open the T&P valve ( unless I was prepared to replace it ) in my experience once you crack a older T&P valve open they’ll almost always seep .. 👍👍

Exactly why I don't recommend tankless unless that is the only option. After considering higher installation cost and maintenance costs, I don't see much advantage over storage water heater other than space saving. It would make sense gas prices were much higher than it is right now, but where I live, there isn't that much of savings. My gas bill is only around $40 during non heating season.
leave that hot valve closed when you flush the system with the t&p
I never open up the ports until i rinse the lines and heat exchanger by taking water and running it just like i would white vinegar or haymaker
That is a real hacky install! 😮

Thank you. Yes, same process. You could also clean cold water inlet screen and the fresh air screen.
The caps! The sign of a pro.
Thanks for the video! Question. Once I start my submersible pump the flushing starts, but after about 30 secs, water with the descaler solution stops shooting out back into the bucket. Any idea why this would happen? Tia
I would recommend detaching cold side first, then pushing a bunch of water through the hot side, getting all of the unwanted solution out.

I'll have to do some maintenance at my in-laws' place. Theirs is a few years old, so I'll be curious what the water will look like. Maybe this is a dumb question, but can you use an air compressor to flush it, instead of pumping the water out? Just because I already have an air compressor. 😅
If you have a water softener do you still recommend this?
Not gonna lie....I jumped when you almost pulled that pump hose off without shutting the valve again

Depends on who you talk to. Had a heat exchanger I replaced a few weeks ago on a 7 year old Navien. No questions asked they swapped it out. Tankless was flushed yearly by the homeowner and that was good enough for them
Can you flush from just one side? The valve to the cold side isn't accessible. (The plumber that installed it helped flip the house and didn't care about what he was doing).
Open the cold after and keep the hot closed to flush out any remaining solution. Opening the hot side will surely send solution to fixtures in house. It’s very acidic so fill a couple of buckets to flush it out before opening the hot side.
Of all the tankless water heaters I have installed, no one has ever called me back to do the annual flush. So sad.

What’s the reason for this for limescale or something and how come the prv is on the hot in Britain ours goes on the cold as hot expands it goes back into cold and through blow off
How does it do with whole house reverse osmosis from well at 66 TDS?
When the hose is in the water while the pump is going it stop it from coming out properly and fully empty. I used a siphon to clean my fist tanks. If I leave the hose that is filling under the water it’ll stop filling for some reason. Idk the physics but jus wanna make sure that ain’t happening to your tanks and it still has water or one.
totally easy to do yourself.

Is that galvanize steel?
You always want to remove the filter. Put it in the bucket so it can be soaking when you flush the tank with water heater. I do it for about forty five minutes.
Will this help if the error message 13 pops up?
Yeah, because the homeowner’s gonna go through all that bullshit
Get you a 5 gallon bucket, a $75 dollar pump off of Amazon, 3 gallons of vinegar & let it run 2-4 hours. Then check the screen to make sure that’s clear as well. Then have a second bucket with clean water to flush out the vinegar for 1 min. Repeat every 12 months.

hmm..I don't agree with your last part where you flush out the vinegar out of the system..you show by forcing safety relief valve spring handle, it is quite common plumbers treating that safety relief like a regular valve, if it sat there for a while and play with valve it may start leaking, thus the exact way you were flushing the heat exchanger by closing both valves (cold and hot), but this time you open cold ,LEAVE hose attached to the hot outlet side with valve to end user off but the drain opened with hose into drain..easy-peasy, without disturbing safety relief valve..that's the plumba'way..no offense 😮
