This is for a 35 gal electric w/h. The 2 fpt stubouts are for thermometer but waiting on the thermometer wells. I do know the soldering sucks and I'll leave it at that. Tell me what you think, be honest.

Is the valve going to the expansion tank the style with the built in relief valve? It does not appear to be.
If not, that valve is just a waste of money.
Is that a mixing valve it looks like?! Can you explain why thats there? Sorta confused by that.

It looks good ben, I like the idea of the ball valve installed just for the expansion tank, this also helps for isolation purposes.
I have a silly question, is this residential?
why the mixing valve, the thermometers?? how hot do you expect a 30 gallon electric to get???

Wait a minute, I follow the National Standard Plumbing Code and it's ill-legal to have a valve in between the water heater and the expansion tank. Due to the fact that someone could just shut off the valve, making the expansion tank pointless/useless.

valves are never a waste of money ,it will make changing the tank a lot easier if it is bad .and you have a relief on the heater

if it is i take the handle off and the inspector will pass it
ben good job but your stubs for the thermometer's look a little far from the flow of water to get a good temp reading

thats a thermostatic control valve, or a mixer, it maintains a certain water temp, making sure the water doles not get to hot
my question is, why all the temp control on an electric water heater?? a 30 gallon, what appears to be a residential:confused:
boilers or commercial water heaters, yes....

Same here. I don't recall ever installing a mixing valve on a small residential electric heater.
Anyway, its a nice-looking installation overall gearjunkie.
And the ball-valve on the expansion tank is a cool idea. The only reason I know its illegal is because I did it once too and bragged about it being superior to my boss, he of course corrected me....oops. Still a cool idea though to make changing it easier.

Forget what you've been told. Forget what you think you know. Storage tanks can and do harbor and breed legionella bacteria.
70 to 80 °C (158 to 176 °F) - Disinfection range
At 66 °C (151 °F) - Legionellae die within 2 minutes
At 60 °C (140 °F) - Legionellae die within 32 minutes
At 55 °C (131 °F) - Legionellae die within 5 to 6 hours
50 to 55 °C (122 to 131 °F) - They can survive but do not multiply
20 to 50 °C (68 to 122 °F)- Legionellae growth range
35 to 46 °C (95 to 115 °F) - Ideal growth range
Below 20 °C (68 °F) - Legionellae can survive but are dormant
Water heaters should be set at 140 degrees to kill the bacteria within the tank. Clorinated water has little if any effect on legionella except when used in very high (and dangerous) concentrations.
The correct thing to do is set the heater at 140 and install a tempering valve at the outlet to bring the water temperature down to 110 degrees. If hot water pipes exceed 100' the tempering valves should be installed at the fixtures because legionella can survive in the piping.
Take a look at Watts's web site. they have some very good information there, including a video called Danger, scalding lurks.

ben good job but your stubs for the thermometer's look a little far from the flow of water to get a good temp readingHow close do you think it should be? The wells are 4" long. Do the wells need to be brass or can they be S/S?
my question is, why all the temp control on an electric water heater?? a 30 gallon, what appears to be a residential:confused: . Built according to prints. I get an isometric and decide where to place the valves
dont you need unions on your heaters? Not on the prints and I see no reason to as it's one more connection that can fail. W/H last 6-12 years so adding 4 extra joints and 10 mins. extra time to replace it seems worth it to eliminate a fitting that can possibly fail. And yes, this is from the guy who says sharkbites aren't the worst thing in the world.
A little background on the place. This is the same project with the flushometer cpvc stubouts. Let me know if you want to see pics on how that came out(I didn't do the work and still refuse that to this). The navy and virginia go by ICC (IPC). Every navy job I've every seen uses tempering valves. Not sure if it matters but start to finish was 2 hours.

Wanted to double check the code for the valve on the expansion tank. In the 2006 IPC section 607 is hot water supply system and I couldn't find anything about prohibited valve locations.
Couldn't find anything about requiring unions on a w/h(chapter 5).If anyone comes up with anything different on either one, let me know.

not sure if it only was for commercial, multi unit installations or included residential too?

and yes we do require unions on the heater. i also provide one at the pressure relief valve too.

Maybe on the side of the expansion tank you should put the web address of DUNBAR'S video of expansion tank failure---and a date that this one should be changed with your phone # at the bottom.
Is that an rp or a double check and what does it serve?

I was training someone and let him do half the joints. He made some gorilla joints(ugly as Xuck but strong as hell) but he was learning. I was training him and am responsible for his work so I can't cop out and blame any bad workmanship on him. Use a wire brush in your drill, cut copper with a sawzall, norton pads to clean the pipe and a uni bit to ream the pipe and 2 hours was easy time. I did have my helper use a tubing cutter(lenox of course) cause he butchered too many joints with a sawzall.
That tank doesn't come with heat traps and I don't care for them as they can freeze up and cause future problems, particularly the ball style. The brass nipples are screwed directly into the tank.

pretty much the same here too. in fact, even the trap primers are no longer adjustable out here.
a check valve is typically found with recirc. systems.
almost all pressure regulators have a thermal expansion bypass. as long as the city pressure is well below 150#, the bypass will allow the pressure back into the main. we don't have meter backflow protection for the most part. although santa monica is starting to ask for it on commercial applications.

I won't you hurt you too bad :p
just a couple of things.....
5 ball valves for a water heater install is excessive
1 too many gauges (unless the schematics call for these)
The wells won't read the water temp accurately at their current location
Top of the heater outlet where the 90 is should have been a tee with temp well on top
I prefer a round temp. gauges with a soldered well way less money than a verticle glass style
Relief valve is on the side of heater or in the middle between the hot & cold?
Could have put the well there :confused:
Can't read the dial on the mixing valve without standing on your head

On the side, just a typical PRV with a piece of 3/4" copper running straight down
Could have put the well there :confused:say again?
Can't read the dial on the mixing valve without standing on your head You can't see it in the pics but the tempering valve has a number indicator on the front

The valve on the exp tank is excessive IMO. May not be allowed by IPC. Still not clear on that yet.
Gauge on tempered water
Figures....engineers specing $75 gauges on a 40 gallon heater
The outlet in the middle is a 3/4" plug. Take that out with a 1/2" drive and put a temp well there
It's not required but I got into the habit of putting vacuum reliefs on all electric heaters whether they are in attic or not. Watts 36A?
Negative pressure will syphon the water out of the heater and burn the elements. It's cheaper than a new element. Surprised engineers didn't spec that as well

With a heater in the attic, main water was shut off and faucet open, syphoning occurs.
The hole in the dip tube doesn't provide enough protection for me on the syphoning

I know there's a happy median here and am just trying to find it. Would a well placed in a bypass work better?

ben when i put a thermometer in i take the well and hold it up to the pipe it is going in to see what type of adapter i need so the bottom of the well is just in the water flow 1/16 " . some times i need a small piece of pipe and a fip adapter and a lot of times i use a fitting x fip adapter .
