I recently replaced the washer on my hot water tap in the shower a couple of weeks ago. First time ever I'd done one. Prior to replacing the washer I turned it off as hard as possible for a long time rather than fixing the washer asap. One day it turned so far around that the water came back on and I was forced to replace the washer. I'd noticed in the past couple of days I had to turn it off harder and this morning when I turned it off, the tap again turned right around and the water came back in. It's dripping fast enough now that I've put a bucket under it to catch the water.
I'm wondering if anyone can advise me how to fix this as I don't want to be doing washers every 2 weeks. I couldn't find anything online. The taps are about 20 years old, and maybe I need to replace that instead.
Any advice would be appreciated.
