I have a Price Pfister Traditional Chrome Roman Tub Faucet Model #WR2700C. It is a brand new faucet, just installed it. I'm getting a very slow drip from the faucet. What can I do to stope the leak completely. Are the valve stem defective or what?

If you will make contact with George at M-One-Specialites he can track that down for you and help you get that fixed.
He has a very extensive list of repair parts for faucets and knowledge of how these work.

most home depots, lowes, should have them, if not go to your nearest plumbing dealer, they should have them

Remove and clean the Price Pfister aerator. Turn the water on after you remove the aerator and check the flow-rate. Many new Lavatory and kitchen faucets are now equipped with Eco friendly water saver aerators. if the flow is normal without the aerator, the faucet is OK. if you want more water flow from your lavatory faucet, you will need to buy one of the old style high flow aerators from your hardware store. If you remove the aerator and still get low pressure from both hot and cold faucets, you may need to replace the faucet. Call the Price Pfister warranty phone number that came with your faucet.

some of these new faucets are "soft off" which means the will drip or run for a second or 2 before the water stops. I know this can be annoying, but it is how some of them are made

Depending on age of faucet it may be wore in valve itself they make seat tool to use in valve to let washer seat like it should.

Brass in vavle will wear after years and won't let new washers seat to stop leak it's something you can check out.

MOST LIKELY YOU HAVE A CLOG AT THE SEAT ON THE INSIDE OF THE FAUCET, TYPICALLY SAND, PEBBLES, OR PIPE SEALANT. TURN THE WATER OFF, UN-SCREW THE HANDLE, REMOVE THE SET SCREW LOCATED INSIDE THE HANDLE BODY, PULL THE HANDLE BODY UP, LOOSEN THE NUT, REMOVE THE SEATS AND STEM AND UN-CLOG THEM.

you may have something in the line,take it off and check both the line and the handheld.

The Price Phister Roman tub spout needs to be tightened from beneath.
If you do not have a removable skirt on the tub it will be a bit difficult to tighten.
Should you have crawl space under the tub and are careful to locate the dead space between the tub and the skirt you can cut a hole beneath the valve and spout location and reach up from below to tighten the spout.
If you have tile as a surround and no access from below you will have to remove some of the tile in order to gain access.

You may want to call in a proffessional plumber to handle this.

Hope this helps,

there is an o-ring inside the valve that seals. It has failed. They should sell a rebuild kit where you bought it, or dis-assemble, and take the failed oring in to have it matched to a new one.

it's the thermostatic valvle to be regulated
