Checked with manufacturer and shower valve replacement no longer available. Do not want to tear out wall. Could I put in a shower cut off valve at shower head as long as I make sure to turn off main handle also? There are valves on Amazon that say they cut off the water completely. Thank you.

It would be a very rare shower valve that cannot be repaired. What is the make and model?

The make is American Standard and I sent pix to them several years ago and the e-mail I received back was no part available for it. It is a one handle unit. Then the drip was occasional but now the drip is constant. Our local plumber was the one who told me to contact manufacturer as he couldn't find part to repair.

If you put a valve at the showerhead, it's quite likely that you'll get crossover thru the faucet, meaning your hot water won't work correctly thru the rest of the house. Can you share those pictures with us, someone here may have the parts you need.

Early Am Standard shower valves, were sold to TAPCO-div of Elias Industries in PA several decades ago. Today, they can tell you no parts available. However, if you contact TAPCO, with a picture of what you need, they can best advise you.

Best Wishes

How about a picture of your faucet. I think you were advised incorrectly.I assume you have a Re-Nu fixture, and if so BPIsite.com should have what you need.

Thanks. Will try contacting the 2 suggested sites. Will submit pictures here if can figure out how to do it.
