I opened my single-handled Moen faucet to check the cartrigde washers/o-rings (due to a small leak). After replacing I have poor water pressure. Any suggestions? Greatly appreciated. AE

At the time you had the faucet apart did you turn the water back on to flush out the supplies and valve body? Try this! Unscrew the aerator,(see image) from the spout and turn the water on if you get a good stream check and clean the aerator screens. Let me know what you find. Good luck and thank you for rating my answer Tom
