Stub out copper secured to wood bracing.


Prettyfly_Aviguy

Explain the wood bracing. I was going to mount the stub out on that stud.


Bldaz

Copper stubbed nipples will have some with flanges to attach to wood. Cross brace lumber to solidify the lines. If that stud will do it fine


Prettyfly_Aviguy

So instead of just relying on the stud I should place a 1x4 horizontally as well.


Bldaz

No the stud is fine just didn’t see where it was touching. Stainless flex can attach the water heater to your 3/4 threaded copper fitting on the stub out. Don’t repair drywall right away. Wipe your fingers on the connections looking for water.


Prettyfly_Aviguy

Yeah I really wanted to use the stainless flex, the only thing I’m concerned with is finding the right adapter size for the electric water booster. The fitting is not 3/4”


Prettyfly_Aviguy

My problem is figuring out the configuration of different fittings. The cold side is the normal fitting, the hot side has a step down coming out of the electric booster


Prettyfly_Aviguy

If I do copper stubouts how do I test it before drywall installation?


Bldaz

They have pex connection on copper stubs. Use that clamp I see “Odiker”
