sprung a leak in fresh water tank on 360

[copsuno]

Ok folks, anyone have a problem with a leak in fresh water tank, this would be at the area of the fitting that feeds the water pump. Thought it was loose connection so took out 8 screws to false cover and removed it and found that the leak occurred at the plastic female couple glued to tank, on bottom left side of tank, and the the water pump line screws into this fitting. The fitting has a large washer type at base of water tank and that is where the leak is. The water pump is bolted to a piece of wood, along which the water lines pass thru, and this leak would have rotted this board if not caught. Will be taking motor home to shop again, may have a ford engine, but quality is not job 1.

i wonder if the vibration of you pump running, is the reason for the leak ???

The plastic tanks can be welded to be repaired. I've done it. It is bascily a heat gun that blows hot air and there is plastic welding rod. All the units I've had the fittings are welded to the tanks. If your not careful when tightening the fittings you can over tighten and split the female side. Always use teflon tape and not pipe sealant. Tape needs to be applied in the direction of the thread. Start off at the beggining and work your way up overlaying the tape. If you are afraid of splitting the coupling on the tank and there is enough room put a hose clamp on it to help support it. Leave it on, wont hurt anything. Look for a plastic company that does fabrication in your area. They could probably fiv it pretty easy.

Thanks to all responses, was able to use a glue gun to re seal around the fitting. Had unit 2.5 months before leak, most likely caused by lack of glue and vibration from road. Here's hoping the patch works, as am leaving for 3k trip in three weeks. Safe travels to all.

Plastic like metals really needs to be fused together. Many time an overlay will work for a short period of time
