My Price Pfhister kitchen faucet has low water pressure on the hot side only,, when I use the sprayer it seems fine and the cold is fine,it is a kind that has 2 ceramic knobs and a separate sprayer,, thanks for the help, Chris

Shut the water off to the valve and open up the hot side. Clear out any crud in the inlet ports in the cartridge. Now open up the stops and flush out the supplies. You should have a full stream while flushing the supplies. Reassemble and test. Good luck, Tom

Not too sure what you mean the cartdidges,, you want me to take it apart?? I did take apart the shut offs today to find out they were not working right, that was some part of this now they both have water pressure but not good water pressure,, please explain a bit more,, thanks chris

One handle or two/three knobs? Regards, Tom

Hello,,
2 knobs,, 1 on each side of faucet with a sprayer,, thanks Chris

Your faucet's built like this, (see image). Shut the water off to the faucet and remove the left (Hot) handle, stem and washer asseembly. Now hold a pan over the open valve body and turn the hot water supply on for a 15 count. You swould have a strong stream of hot water coming out of the open valve body. If not then click on back. Good luck, Tom
