Low Pressure in Tub and Shower Faucet

Question: The water in the bath / shower in our guest bathroom has started running very slowly. The water at that basin and in the rest of the house works fine. Any idea where to start?

Answer:

I think your Bath/Shower cartridge is clogged up. You can buy a replacement shower valve cartridge at a home store. First, turn off the water main to the home or the bathroom. Then, take off the handle and shower trim. Then you will see a cartridge that can be removed either buy unscrewing or pulling out a retainer ring.

Take the old cartridge to the hardware store and match it up. If your shower is an off brand, this may be harder to find.
