Installing flush valves on an ecosmart ECO 27 electric tankless water heater

How I added flush valves to an ecosmart ECO 27 electric tankless water heater.
These flush valves will allow me to flush out the water heater and clean scale buildup.
I used flush valves linked below, and to pump, a Superior Pump 1/4 HP submersible pump (see below).

I have the same tankless water heater, I'm about to buy the isolation valve kit and possibly an in-line scale inhibitor to install, debating on the latter. I'm not a plumber either, so no worries about the perfection, we've all been there! Thank you for posting your installation!

Excellent presentation, Parker. Thank You, mac

Nice new wrenches!

Plumber here that has that very heater. 100.00 worth of parts and a pump and a Saturday afternoon is a lot to spend to extend the life of a 500.00 heater. Also you could have just disconnected the blue and red hoses and used them with the pump instead of all that.
Correct that a tankless system doesn't require a T+P valve
metal to metal connections are tapered or cone shaped threads that get tighter the more they are wrenched. I use two wrenches that are at least 12" long on these and pull hard too.

Both good points. Plumber beats DIY’er :) hopefully this can help some others and I like making the videos, but good thoughts for my next go-around. Luckily the heater is down to only $400. I wonder how often I’d have to replace vs flush though.

This is a good tip on using flexible supply lines instead of installing flush valves. About to put one of these in.

Hey buddy you’re tools did the job no worries and it’s a nice job I have to order these valves to install on mine but in future videos kinda angle the camera as so you’re rear end is not blocking what you’re trying to do you have several blank video shoots overall great work I like it kudos

[@jpfath]

Haha thanks, good points. I’m not always aware of the angles. Glad you enjoyed it!

Will you please tell us what is the thread for "service" port? why it doesn't accept the inlet or outlet connector thread?

[@moroniccolonic3959]

Very informational video. I'd check out some videos on how to plumbers tape though.

[@jpfath]

Yeah I think you’re right. Could use some more practice. Might have been well-served to use some pipe dope as well. The good news is, in the last several months since it’s been installed, it doesn’t seem to leak during usage.

[@moroniccolonic3959]

@@jpfath no leaks is really all that matters 😁. I've had plumbers tell me anywhere between 3 and 10 wraps. I find 3-4 wraps around the pipe sufficient.

@@moroniccolonic3959Teflon tape comes in different thicknesses. The cheap thin stuff use 10 wraps. The thicker stuff I think you can get away with 4 wraps

I had an electrician say you can’t put all those wires together in one conduit but every Eco Smart I’ve seen installed is done using only one conduit. Thoughts?

[@jpfath]

@@simpleagain1 I’m not an electrician (and I paid one to run the circuits) so I can’t say for sure what’s kosher, but it seems to work ok from my year and a half or so of experience with this one. Can’t remember if I show in this video, but it’s actually 3 separate 240V circuit breakers and circuits.

great video

What is the size of your inlet/outlet fittings? Will this valve work on an 1/2” inlet? If not, what do I do about that? Help plz!

[@jpfath]

I believe the inlet and outlet are both 3/4" so this part wouldn't work directly with a 1/2" inlet. I think 3/4" is pretty standard size, so I'm surprised that you have a 1/2". In that case, you could adapt it to 1/2" on either end, or try to rig something up. Trying a couple Google searches, I've seen some things that look like they could work, under "1/2" valve with drain" - I can't say for sure, but maybe that would work?

[@simpleagain1]

Wrap the thin Teflon tape 10 times around the thread before making the connection. Some guys will use dope on top of Teflon tape for water tight seals
