I have a combination bathtub and shower and over the past three months or so I noticed that whenever I turned the lever to “shower” I still had a fair amount of water coming out of the tub faucet. Basically, water was leaking from the shower valve and coming out my tub faucet.

My dated and barely working shower knob.The water coming from out of the tub faucet was clearly taking away from the water pressure that was getting to the shower hose and nozzle. This means that whenever the shower was being run in my house we’d have to crank the water all the way up just to get enough water pressure out to take a decent shower. And while showering water was gushing out of the bath tub faucet below, immediately going down the drain and becoming a huge waste of water. I also found that if I had the water pressure turned on just right I’d manage to get the pipes banging and hammering in my walls.
