FRESH WATER TANK VALVE


SCRIPAL

Recommended Posts

The fresh water tank valve on my 89 Dolphin is very difficult to turn on and off and needs to be replaced.  Is the 3/8" valve the correct size for the water line?  Any help appreciated.

If you are talking about the drain valve that has a tube sticking below the floor, Mine kept getting so hard to turn  to drain even with channel lock pliers. I unscrewed the strap that held the tank in place in front and put a wedge 2x4 (like a doorstop)  under it and raised it up enough to unscrew the drain valve. When I got it removed there were plastic slivers embedded in the drain hole like where they drilled the tank to put the fittings in. I took the inlet hose off and put a small vacuum hose down in the tank and more slivers got sucked up .  After that  I really flushed the tank out with a water hose .  (What a crock to have to do because of others [ tank builder]  neglect).  I ordered a new one from ebay, installed it and have had no problem since. Hope you solve your dismay.

Hi Al! I only use the on board pump to drain my fresh water tank. The fear of fooling around with valves that are over 25 years old and they suddenly develops a leak after you attempt to use them again isn’t far from my mind! Good Luck!
