I'm curious...
Had it occured to you that you were talking to plumbers here?
Of course...and so does everyone that comes to this site looking for help, to do it themselves. Isn't that the purpose?
It's like a bad car accident, I just can't stop looking at it. I've thought about this for awhile before saying this but honesty, if I ran across this set up I would just pull it all down and start over again. Right back to pulling the 1/2 wafer board off the wall and putting 3/4 plywood up instead. I am a fan of pex but this is not the place to use it. All of the piping from the tankless to the manifolds should be done in copper, both for rigidity and looks. The gas line should be moved away from the vent pipe. The relief valve should be hard piped to a threaded tee and hard piped to 6" from the floor. The expansion tank should be solidly hung on rigid pipe not mechanics strap. The whole thing is a mess. If the city mechanical inspector ran across this he would probably have an aneurism on the spot. Here is a prime example of a little bit of knowledge gone wild.
You're jealous...i can tell. A mess?...well angels to some, devils to others...i've seen some professional plumbing work that I think is messy...
It's not 1/2" wafer board, it's 3/4 tongue and groove OSB sealed with water proof sealant on all edges and face, counter sunk into pressure treated 2x6.
Copper for looks? that's so 1985...and who cares what my mechanical room looks like?! I'm not shooting for the cover of Vanity Fair, or plumbers weekly.
I have 2 relief valves per the inspectors cue, since there is no drain in site there is a 150psi valve attached to the tank, and a 120psi valve above grade for gravity drain...
The expansion tank is sitting on a 4" piece of ABS (updated after this photo) the straps are there for 'looks'.
I'd never put a sharkbite fitting behind a wall, the purpose of my home run is to avoid having fittings behind walls.
I'm glad at a minimum i've given you some fodder for your next "what not to do" thread...I'm pretty happy with it, and it works.
GO SOX.
