Can't seem to get a tight seal at the connection of the pvc fitting to metal. I sanded th piece of gal to try to eliminate some of the corrosion because I could not get to oring on the pipe. Should I use a sealer as well there were no directions with the pvc piece I bought.

Thanks

Wrap three turns of Teflon Tape clockwise around the threads and try again. Good luck, Tom

Thank you for the reply...

Where the leak is there is no threads it a 3 piece pvc cuplin... I think the leak is between the rubber and the metal or the pvc and rubber.

Tampa, can you tell us exactly what 3 pice coupling you bought. I think its possible you are trying to get parts to do things they aren't designed to do. Is this a Fernco coupler? Flexible plumbing connectors, fittings, couplings, adaptors, patches for PVC and clay pipes.

Maybe using a pvc union of some sort?

Sorry neighbor, I thought you had a regular PVC connection to Galvanized which consists of a PVC FemaleThreaded Coupling to a male thread on the metal pipe. Answer Bobs question and we'll get back to you. Regards, Tom

It sounds like you are talking about a 'Dressler' type coupling.

Does it look similar to the photo linked above?

If it is, hopefully you aren't trying to use this indoors.

Dressler couplings are designed to be buried outdoors in situations where opposing force from the two pieces of piping being joined helps to lock the coupling in -- They will blow apart if they aren't back stopped.

If this is indoors, you need to back the steel pipe out to a female fitting and take off from that point with a plastic male adapter -- Do not use a plastic female adapter on steel male pipe threads, the plastic female fitting can and will eventually split, most likely while you're away for the weekend.
