I have similar problem to similar recently posted question. Problem is with both hot and cold feed with mixer faucet. Water pump in basement from gravity fed well system. I have checked for leaks (None) opened all valves to full, all pipes leading to kitchen are insulated, aerator dismantled and checked (Clear) but still problem persists. Help me keep my hair please.

" Problem is with both hot and cold feed with mixer faucet."
Are you saying that you opened up the faucet and flushed the supplies and still have no pressure? Tom

I am not familiar with how to flush system so I suppose my answer woule be NO! :)

Shut the water off and take the faucet apart. Check the cartridge inlet ports for trash and a clog. Now, while the faucet's apart place a pan over the open faucet to prevent splash and turn the water back on for a minute to flush out the supplies. You should have a strong stream, if not click on back. If so then reassemble and test. Good luck, Tom

Seems I have a dual problem, some kind of pressure activated valve in faucet, and water feeding back into water tank in basement. Friend of mine scratched his head a lot, but managed to finally track problem down with your guidance. Really appreciate the help.GREAT SITE!!
