Can you replace a sprayer head on a 7065 moen vestige faucet

pop the cover off the top of the spout tighten the screw underneath and replace the cap.

You can find replacement parts on amazon, click here Award winning faucets and shower heads and take a look. Cheers

first the water needs to be shut off, then with an allan wrench if i remember it should be 1/8. the allan screw is located in the handle. remove the screw completely and under the handle should be a nut, with a crescent wrench remove the nut and the cartridge should be ready to be removed. it is going to be difficult to come out with out the proper moen tool but vise grips will help as you have to pull straight up. if you find a plumping wholesale and give them the model # they should be able to give you the right cartridge. or if you call moen the will ship you one either way it should be free as that is a warranty item.

The faucet is defective . You will have to replace it with anew unit.

Take off handle and spin stem 180 degrees,should solve

If it's leaking at sprayer, and not the base where connected to hose, try this. Buy a bottle or jug of CLR. (calcium, lime, rust ) from hardware store, and pour enough in a bowl that will submerse sprayer in it. When you go to bed, or out for a few hours, turn off both taps (obviously) and relieve all pressure as well from sprayer. Now wrap an elastic around the handle of the sprayer so that lever is depressed, and submerse it in the bowl of CLR, and let it work overnight or at least for a few hours. Next Day, or Later, remove elastic from sprayer, and try it a few times and see if leak has stopped. Quite often you get calcium build up on internal washer/seal, and this will clean it off. If no CLR, you can try vinegar as well, but I find CLR better. If it appears better but not stopped completely, give it another treatment.

Hot water line connected to left side of faucet? Did you replace tap set, or just cartridge? Cartridge may be out 180 degrees.

Yes, a cartridge will probably solve it. There are two different Moen cartridges so be sure to take the old one with you so you get the correct one.

call moen for new cartridge
