Gray water tank


New Member
83 Southwind How do you remove the gray water tank? Taken off holding straps, unscrewed bath tub drain. The tub drain just keeps turning. Is this the right why to do it? Can't see any other fittings. Help please

Re: Gray water tank

Since no one has as yet responded, I'll try to help. There is a good chance that the plumbing into the tank is glued in place. I doubt that removal of the tub drain would gain anything at all. The drain lines from the sink, the kitchen and the tub probably all connect into a common drain line that then goes to the tank. There could also be a vent line, though most gray tanks don't have that. If there is only one plumbing vent on the roof, it will be for the black tank. You need to find some way to see the point where the drain line enters the tank.
