    Hello,

    I have installed a new delta single handle faucet with side sprayer. I’ve had a few different delta faucets in the kitchen and none have done this. When turning on the hot or cold water it makes a thumping sound. I changed the low flow strainer to a higher flow.. still thumps. Made sure sprayer hose was filled and it still thumps. Have notice it leaks slightly when turned off. Called delta, they sent a divertor.. still thumps. Called again, they sent new ball valve with seats, etc, no help. Any ideas?

    regards,
    RM

    The pipe thumps correct? Might need to add an inline hammer arrester.

    Make sure valves are all the way open under sink. Also try without aerator

    How old is it? Delta has lifetime warranty
