FredNewell Posted August 21, 2017 Share Posted August 21, 2017 (edited) Not really an oops, but I learned something after 35 years of RVing. My dolphin has a couple of drain valves for the domestic water. They are angle valves that dump through the floor to the driveway. There is a circular pull that looks like the pull ring on a hand grenade. I discovered this today while reinstalling my water heater plumbing. Pretty cool. They are on the floor of the closet, under the water heater. Pull the ring and the water drains. I avoid living where it freezes, or where air conditioning is used. I usually do very little to winterize. Never had a problem. Edited August 21, 2017 by FredNewell Quote Link to comment Share on other sites More sharing options...
markwilliam1 Posted August 24, 2017 Share Posted August 24, 2017 Well Mr. Leakman Fred LOL. I have the same type of pull rings on Grannie. After reading another post of someone pulling up the rings and now has a leak there I don't touch nothing! That old plumbing scares me! When I replaced my toilet I held my breath when turning the pump on. No leaks! Quote Link to comment Share on other sites More sharing options...

If your drain valves are like mine, there is an easy fix for a possible leak if you use the valves. Mine did just that when we first got our Dolphin. I used them to drain the system and afterward, one of them leaked. I discovered that the valves, ( in my case they are T-valves that pull up to drain the system) pull completely out. They have an O-ring on them that gets funky with age. I replaced the O-ring on the the leaky T-post and, voila!, leak fixed. Quote Link to comment Share on other sites More sharing options...
