Toilets, Sinks, Showers, Tubs and Disposals - no pressure faucets

In my 2 upstairs bathrooms, the sinks have lost a lot of pressure and the shower has seemed to gain a lot. Also the faucet in the kitchen, the hot water has lost pressure, but the cold water is fine. Any suggestions would be greatly appreciated

On the upstairs faucets I would remove the aerators and clean. When you remove them, turn on the water to see if the pressure increases. Kitchen. go underneath and shut off the supply line to the hot water. Disconnest the line from the valve and hold a rag over it. Turn it on and off 2 or 3 times and then reinstall the supply line. May be deposits hanging up in the valve. Might have to do same in bathrooms. Good luck and post back.

I replaced the two aerators and the sinks work great. I will try what you said about the kitchen very soon and let you know, thanks again.
