He traced the hose for the flusher up across the water heater, down by the fresh water tank intake and back down under to the black tank. Said that was ridiculous and I agree, so will run one more direct when he comes back. Would there be any good reason to run 10 feet of hose when three or four would do it?
Thank you whoever you are!
Yes, that is actually a Pubic Health requirement (vertical loop with vac breaker) sole purpose is any direct connected tank cannot syphon back to system fresh water mains if shore pressure is lost.
Good to hear they showed up, sounded as though they were no show in your 1st post.
