Have you removed the aerator and checked the screens? If that don't help I'll need the type, One handle or two knobs? And the brand name plus its age.

Yes, I checked the aerator and cleaned the screens with a toothbrush, but still no help. The faucet is a two handle Delta, probably about 15 years old, I'm pretty sure it is the original equipment installed when the house was built.

Did you test the pressure with the areator removed? If it was still weak then the problem lies in the cartridge assemblies, (see image). Shut the water off and remove the Delta# 1740 Stem unit assembly and then remove the Delta#4993 seat and spring from the assembly. Once the valve is open turn the water back on to flush out the supplies. You should have a full stream coming out of the open valve body. Now turn your attention to the cartridge and clean out anycrud you may find. If that doesn't get it then take the stem unit assemblies with the seata and springs down tom a Derlta dealer and replace them. Reassemble and test. Good luck, Tom
