It is a price pfister, single handle pullout faucet (no side sprayer), it seems all of sudden I started losing pressure, particularly on the hot water side. The pressure in the rest of the house is fine. Any ideas why this would happen and how to fix it? I cleaned the aerator but that didn’t do anything.

I have a single handle, older model delta faucet. I’m not sure what the model is because I am renting. Water pressure works great everywhere else in the house. I already took off the aerator and cleaned the debris. I also took off the faucet itself and the water pressure is fine for cold water from the hose, but the hot water barely drips out. What could this possibly be??

Thank you for your help!

My kitchen sink has only one handle for hot and cold. When you turn it on, everything works fine but then it slowly decreases to just a drip. Also, when i remove the aerator and turn the faucet on it doesn’t even flow fast at the beginning. It’s just a drip. I think this means i should replace the aerator but I’m not sure. Any advice.

I have checked the water lines going in to the faucet and they have plenty of pressure. I have taken off the aerator and cleaned; turned the water on without it on and still nothing. I have disconnected the lines going into the faucet and blown air into the faucet to try to break free any build up in the line but this also had no affect (except making me a little dizzy).

With these "tests" done, I am thinking that there must be a problem inside the faucet handle i.e. the cartridge.

I took off the handle and under that is a plastic piece that turns about a total of 90 degrees (as much as the handle normally would); it also pivots up and down (like the handle as well). I imagine I need to get this piece out in order to get to the cartridge, washer, etc; this is where the real problem starts. This plastic piece does not simply pull up and out and the does not seem to have any type of pin or screw etc holding it in place. It does have "teeth" around it (imagine you are looking into a socket, the teeth are like that). I’m guessing that I need to find a tool to fit in there (if one exists) to unscrew that piece.

Just moved into the house so there is no owners manual available and I cannot seem to find any type of manufacturing label for the faucet. Any help, ideas, answers etc. would be greatly appreciated.

Thanks

Periodically, the pressure in my kitchen faucet gets so low the water reduces to only a trickle. Happens with Hot or cold water. The sprayer however works fine. Problem usually occurs after the faucet has been running for a while (but I cannot always recreate it when I want to…it is sporatic). I have a single handle Moen faucet. I have removed Aerator. I have replaced the cartridge. The valves are fully open. No pressure problems anywhere else in the house. Any ideas?

Removal of the aerator does not help. No one touched the supply valves, the other faucets have normal flow, all pipes are copper. Flow was normal for the first year or two. This time of year the supply water is much colder than it has been, but well above freezing. Should I disassemble the faucet and look for anything? Some adjustment?
I apologize now that I see the question is ambiguous. The flow has already reduced, I am not hasing how to reduce it. Sorry!
