Gate Valve Replacement

I don't know if there is a good, better, or best valve. Mine leaked when new and it took the dealer 3 tries to fix it.
Buy a new valve and let us know.

take it off and clean it.

Valterra is likely what's on there an it's likely what you should replace it with. I just did my black tank valve and all the cleaning in the world would not have fixed it. However, I later found that they sell just the seals and replacing the seals alone would also have fixed the problem. If you can see the name on the side of the valve, see if you can get new seals. It's a very easy job unless you forgot to empty that black tank and tilt the RV the opposite direction! :E

There are only a couple of mfr and they are pretty much the same.

Many times the problem is as simple as the gasket getting out of alignment - the fix however requires you to disassemble the gate valve and many will just replace the entire gate valve as they aren't that expensive.

You are right, for the price of the valve I would just replace it. I only want to do that job once.:R

OK, so does "replacing", which I'm inclined to do, involve cutting off the old one, leaving enough of a "flange" to glue the new one on?

They should be bolt on connections.

Moved to Tech Issues forum from DIY.

NO NO NO NO

The flanges are a one-time install. The valve is sandwiched between those flanges and sealed with a square cross section O-Ring on each side. Little bolts hold the sandwich together. New valve comes with new bolts/nuts and the O-Rings.

Does anyone know where to buy the gate and flanges, included? I want to do a removal of the valve and need the whole thing.
