My outside spigot is leaking from inside of the house. It is leaking at an elbow just below the cutoff valve. The pipe is not copper or metal it is some type of plastic. What do I do in order to stop leak. Also, the spigot outside is not attached to the foundation by any screws. They just caulker around it. Do I just need to put a screw on each side. Is there anything I need to look out for? Thanks.

 

First, you need to determine just what kind of plastic you are dealing with. Could be PVC, CPVC, or even polybutylene, if you are in a mobile home. then get the appropriate fittings needed to make the repair, and the proper type of glue you will need (if any).

If you have a sill **** that has provisions for screwing it to the wall (a flange with screw slots), by all means, do so. If you don't have that, then I would suggest changing the bibb to one that does. Plastic pipe won't take much bending and twisting, especially if it is under pressure. Mounting a sill **** to the wall would eliminate virtually all of the bending and twisting.
