Does Your Tub/Shower Faucet Drip?

If you have a shower with two or three handles on the wall, one hot, one cold and one that changes the water from shower to tub, you have a type of valve that requires washers to be changed. These washers should last 4 to 5 years at least.
If you are having to get those washers changed every year or so, maybe even more often, you have another problem.
The “seats” that the washers press against inside the faucet are in bad shape.
The “seat” is a part of the inside of the faucet. It is a surface that matches the washer that gets replaced.
If your shower or tub starts to drip, water is getting between the seat and washer. What you are seeing is a slow drip, one drip every 5 or 10 seconds, but inside the faucet there is a very small stream of water blasting out from between the seat and washer at 50 to 100 pounds per square inch.
The washer inside the faucet is made of rubber and the seat is made of brass, a soft metal.
The force of the small stream of water blasting out between the washer and the seat actually cuts a groove in the brass seat. This is sort of like the groove cut into the earth by the Colorado river known as the Grand Canyon.
If you replace the old washer with a new soft rubber washer, the rubber can squeeze into the groove that was cut by the water blasting stream. The problem is that the groove cut in the seat will keep cutting small pieces of rubber from the washer and destroy it in short order.
What needs to be done is the seat needs to be repaired or replaced. In my experience of 30 years, about 95% of the time the seat is replaceable. About 5% of the time the seat can be repaired by using a special grinding stone on a rod to re-surface the seat by grinding it smooth.
I know I am now up to what occurs about 100% of the time but there is one more possibility. Less than 1% of the time you need to replace the faucet because the seat is not replaceable and the surface is too thin to re-surface.
So if you are having someone replace the washers, and you have had this done often, ask him to replace the seats also.
