Shower Valve Leak Fixed Right in Grantsville

Sometimes a small drip turns into a much bigger headache. That's exactly what happened here - what started as a leaking shower valve had already been attempted as a DIY fix, and the supply lines inside the wall ended up twisted in the process. At that point, a simple repair wasn't going to cut it.

We opened up the wall to get a clear look at what we were dealing with. The old valve body was corroded and the lines were a mess. There was no salvaging it. The only right move was a full valve replacement, so we pulled everything out and started clean.

We swapped in a Moen Posi-Temp valve - a solid, reliable choice for tub and shower applications. The Posi-Temp is pressure-balancing, which means it protects against sudden temperature swings when someone flushes a toilet or runs the dishwasher. It's built to last, and Moen stands behind their products. Once the new valve was seated and the lines were properly routed, we finished it off with a repair plate to cover the wall opening cleanly.

The finished result is a polished chrome handle and trim that looks sharp and functions exactly the way it should. No more dripping. No more twisted lines behind the wall. Just a properly installed shower valve done the right way. And yes - we got it done on Pioneer Day, because a leak doesn't wait for a holiday.

DIY plumbing repairs can start simple and spiral fast, especially once you're working inside a wall. If your tub or shower is dripping, running hot when it shouldn't, or the handle just doesn't feel right - that's worth getting looked at before it turns into what we found here.
