Leaking Valve

[dale farley]

John, The O ring looks okay, but I will probably change it if I can get it. You are saying "everything else looks fine", you don't mean the diaphragm looks good with that hole in it do you?

[mikedee]

The hole is normal, it is how the valve moves. The valve equalizes pressure with the hole allowing a small amount of energy to open the diaphragm.

I sent the whole deal to Goyen, we should hear something soon.

That hole is what I (perhaps incorrectly) referred to as a "weep-hole" earlier in the thread. If it is gunked up the valve will not open, OR if it is open, it will not close. I had that issue with my CC.

It shouldn't cause a leak. Can you tell where it's leaking? It's probably a hole or tear near the edge of the diaphragm.

Dale, it's a little hard to tell, but in the first picture, it looked like there was a tear in the gasket/diaphragm at around 9 oclock, and 6 oclock? Didn't see it in picture 3 though.

That whole piece is replaceable for about $6-10 as a repair kit. Let me know if you cannot locate a source, and I'll look for where I got mine.

Dale,

Where exactly is your valve leaking? Is it that valve itself, the body or is it that it fails to completely shut off the water when turned off? Should it be the later it probably should be called an internal leak in which case it the diaphragm or junk inside. Should it be the case of the unit itself leaking it is probably the O ring or a fitting perhaps even a hairline crack in the unit....can happen if was ever frozen with liquid inside.

I was wondering the same things, what and where is it leaking?

Unfortunately, I can't tell where the valve is leaking. All I know is that it drips when closed off. Also, when in the closed position, I can blow on it and hear a little air coming through the other side.

At first, I thought it was the hole in the diaphragm, but then I noticed it looked like a factory hole, so I decided that wasn't the source. The "O" ring looks fine, and I don't see any tears in the diaphragm, but I will inspect everything again when I get home from church today.

Greg,

I missed your question yesterday. The valve is one of four that drain water from different sources (water heaters, water lines, fresh water tank, etc.) when you want to drain all the water from the bus. This particular valve drains the fresh water tank itself. When I shut it off, it has a small, constant drip.

Dale if it is a drain valve why does it have a filter strainer on it? Are you sure you are looking at the drain valve?
That valve looks like it's in good condition.
