We remodeled our bathroom a ways back. All new plumbing. My wife noticed a couple of months later, that we had a leak. The bathroom is exposed to the basement which is good. I could see the leak was coming from the kohler twin ell. The twin ell has a 1/2 inch pipe coming out of it to the bath tub spout. I figured it would be as easy as unscrewing the 1/2 inch pipe, taping it, and screwing it back in. The leak only occurs if the shower is turned on. If we are just running water no leak. The twin ell comes with a 3/4 inch hole and a 1/2 step down. After several attempts and no luck, it appears that the leak is coming from around the step down. I can't seem to get the step down out..... Any ideas? Trying not to call the plumber as now it is my problem as I tried to fix it. Oh, and even though the bottom is exposed I can't get to the twin ell very easily (out of reach). I can only see it through the 3/4 inch sub-floor.
So far, I have removed the spout, re-tapped a 1/2 inch piece of threaded pipe, put it into the twin ell, and put a 1/2 inch cap on the end of the pipe, turned the water on. This gets the shower going, and I can clearly see it leaking through the hole for the pipe through the tile. It appears to be coming from around the 3/4 inch to 1/2 inch step down in the picture on the website below. Drip, drip, drip......
Help is appreciated!
