[C320-list] Water Heater Output Tubing

[Dean Vermeire]

Hi Warren,
I purchased fittings and such yesterday to replace the old hose with either a standard supply line or a 6" brass pipe.  If the pipe is long enough, it is my preferred replacement, due to larger inside diameter than the reinforced supply line.  I agree that the black/green exhaust hose should not be used for potable water.  I can't wait to see if the water comes out much fresher, once I have made this repair.
Thanks,
Dean

Seaward(Whale) makes two versions of the water heater: one with engine hose in rear (ours,) and one with engine hose on front. The black/green stripe hose is what I found and replaced last year. Our 1994 does not have Pex hose for potable water. All potable water uses clear plastic hose with reinforcing strips. I would be surprised if black rubber hose is spec'ed for potable water.

I use the following connector for potable hot water for a few years now. My understanding is that the temperate of hot water coming out of the water heater is too hot for Quickconnect pipes.

Are you sure it is the potable water output and not the engine return?
