    I have a new frost proof faucet and it continues to run a small stream when shut off. I'm sure of the inner works of a frost free. Any ideas why it won't completely shut off. Howard

    Frost free wall hydrant use washers same as a compression cartridge, over time the washer molds to the seat and wears out.
    You should be able to remove the nut holding the shaft and replace the washer, but it's not easy most of the time.
    Most frost free's are threaded into a fitting in the wall you may want to replace the unit if you can, it would be easier.

    First question is, what quality of faucet? If you went down to the hardware store and got a junker, then you got a junker. If it's good quality, did you solder it? Or is it a thread-on?

    For most of these type faucets, the problem would be a rock or piece of debris holding the washer off the seat. Or it could simply be a manufacturing defect. If soldered, it could be a drip of solder that got between seat and washer.

    Or a burnt washer? It sits pretty close to the end if you soldered.

    If it old I would go for a replace every time. If is rather new pull it apart and replace the washer and see if the seat is ok. The seat is the part the washer sits on.

    The quarter turn hose bibs do not use washers, and most hose bibs are not threaded to the piping system, most are soldered.

    Some inexpensive frost-free hydrants use an O-ring instead of a compression washer, and I've seen split O-rings in them.

    This is a new 1/4 turn. I removed the stem and did not see anything that was apparent. It did have 2 O rings on it about 1 inch apart. I did not inspect them very close. Howard

    A quarter turn frost-proof. I have never seen one of them. Wish I had one.

    1/4 turn frost proof

    This faucet is a B&K 1/4 turn faucet purchased at Home Depot. Lowes also has an American Valve 1/4 turn around $25. I am going to remove the stem again and see if the O rings might be cracked. I have to do something before hard freeze. Thanks for the replies from all. Will let u know if I find the answer to the problem. Also was not soldered. Threaded into female connection.

    I have seen sillcocks that are female that get threaded onto a brass nipple or male adapter. If it does have male threads then it sounds like a boiler drain acting like a sillcock. I would not waste alot of time dealing with it and just replace it with a new one. What is your time worth to you. What is going to take longer hunting down parts or spin it off and replace with new.

    Problem solved. Even though this was a new out of the box faucet,it was defective. I brought a new one and just exchanged the stem and the water shut off completely. Thanks for all the advice. HOWARD
