I have a Delta Model 470 kitchen faucet.. and just suddenly started getting low water pressure.. I have checked the aerator and found no debris.. should I remove the faucet handle and check there... I am not sure how to do that there is a tiny hole there and I do no know what kinbd of toll would help me remove the handle.Also I saw that some one else had the sam problem and calimed to pull out the inner lining from the hose.. I think.. how do you do that

Is the Delta Model 470 a single lever faucet or does it have two handles. If it is a single handle faucet which I think it is from you mentioning the small hole, it takes a small allen wrench to take the handle off. Then the large nut comes off and the ball and the washers. Parts can be bought at any good hardware store.

LETMETELLU... It is a single lever faucet... will get the allen wrench and let you know what happens... also do you know about this inner lining
