My shower faucet in my master bath is not working. The sink and the tub are both working though in the same bathroom. Any Thoughts on why it is not working?

It sounds like you have some crud that's been sucked up into the inlet port of the cartridge. Shut the water off to the shower valve and open it up. Check and clean the inlet ports in the cartridge. Before you button up the valve turn the water on for a minute to flush any crud out of the supply. Good luck, Tom

We just changed the pressure relief valve on the hot water heater and there is no water in the kitchen facuet only - all other facuets work both hot and cold - what can we do?

Remove the aerator at the end of the faucet spout and clean it... probably clogged up with sediment from the pipes that got disturbed when you turned the water back on to the water heater!

Aerator is probably clogged... see your other post for my reply.
