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
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
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.
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.
