    Hey guys! Was getting a wet spot by doorway of my small master bath. Thought it was the drain seal on my shower stall but when I looked behind the wall ( I have access) I see the drip is coming from a few (not one!) small pinholes in the cast valve body!!! I put this in about 11 years ago so it's not that old. I have water with high iron but not that acidic or hard. What could make a valve head sweat water like that? Just plain poor construction? Anybody ever seen this before?

    I haven't pulled it out yet as I wanted to push the job off till next week. I tried some epoxy but water pressure seems too strong to hold and I can't keep the pressure off on the valve for more than an hour because we need the water flowing in the rest of the house.

    Thanks . . .

    It could be corrosion or, just a hole caused by casting sand used in the molding...

    It doesn't matter it's replacement time...

    There is a rumor that Billy Mays died because he tried to epoxy a pipe under pressure! Yes...you have a situation not often encountered, and yes...you need to replace as soon as possible.

    Depending on the brand, many have a lifetime warranty, and if you call them and explain what's going on, they'll send you a new one. Better than money out of your pocket!

    Usually that indicates a foreign valve which used a poor grade of brass. Many imported items using the poor brass get "holes" in them.

    A porous casting happens, but most good places weed them out. Happens to cast aluminum wheels, too, sometimes which can be a real pain.

    When you wallow in grease, mud, blood, and sewage on a daily basis- yes I think a daily shower is in order. The more water the better.

    ok.. I sent pics of the valve (complete with leaking water and hole in the shower wall) to American Standard and as a 'courtesy' they are sending me a new valve even though I don't have my receipt from 11 years ago.

    How nice of them.
