pvc to galvanized steel?

Hi --
I need to extend the pipe leading outside from my sump pump, but it's never been extended and it's just a piece of galvanized steel pipe, and the end of the pipe is flush with the brick exterior of my house. It's a female end, but the pipe threads have rusted and corroded a bit. Can I just insert a piece of pvc in there without threading it onto the steel pipe? Does pvc glue adhere to steel? Any advice would be appreciated.
Thanks, Dennis

I would try if at all possible to screw a galvanized nipple into the female threads. Then connect the PVC either with a thread fitting or a Fernco.

I would suggest using a galvanized coupling on the end of the nipple if use a threaded PVC adapter. Reason being, the PVC is in tension if it is the female and is more prone to split than the male into the metal female coupling.

Try going to your hardware store and get a clamp on coupling that you clamp on to the hard pipe after you cut the female connection then to the PVC pipe.

This pipe obviously meets an elbow in the basement. Unscrew it there, get a piece of galv pipe that is at least 6 inches longer and replace it. If the pipe is flush with the house, you are wrecking your house. you could also replace that piece from the elbow to the outside with PVC of the same diameter, but you'll probably have to enlarge the hole in the wall a little bit.

Clean the threads with a wire brush. The brush designed for cleaning the inside of copper fittings before soldering would work well. The use a Male PVC fitting with teflon tape or PVC compatable pipe dope screwed into the pipe to attach your PVC extension, which will be glued into the fitting.

Or, if they're really bad, a NPT tap of the right size will clean them right up... :)

What Bob said. The line you are working on isn't pressurized so a bad screw in connection may work. This is the simplest and cheapest solution, try it. If it doesn't work, all you have lost is the cost of 1 male PVC/IPS adapter.
