A few days ago, the city came out and replaced our water meter. When I came home and used the bathroom faucet, I noticed there was air in the system. No problem there, but later that night and the next day, I noticed that faucet - and only that faucet - had extremely low water pressure. Barely a dribble. Additionally, we were getting rusty(?) water on occasion.
I removed the faucet altogether and ran water directly out of the hot and cold hoses from the wall for a second to ensure water pressure there was okay. Everything was fine. I tried to backflush the faucet head just in case there was some debris in there. I put the assembly back, connected the hot water and ran some water through the faucet assembly for maybe two to three seconds. A ton of opaque orange water came out, then cleared up. Then I hooked up the cold water and tested that one, but only a very tiny amount of discoloration occurred. But when I started the cold water, the faucet was already hooked up, so no air in the system.
After putting the whole thing back together, my water pressure is back up, but maybe 80% of what it should be.
It seems I have two problems:
- Why is the water pressure here - and only here - low?
- Why is there occasionally rust(?) coming out?
My best guesses are:
- Some debris in the faucet. I've tried to clean it out (not knowing what I'm doing), so is there a better way to do so, or should I replace it?
- Air in the system lets water move more quickly when first starting and flushes out a ton of stuff in the pipes? (My house is ~50-60 years old.) Or possibly a hot water heater issue? But I don't have enough data to back up either one.
