I am trying to replace a stuck gate valve that does not close,
probably due to hard water. From the gate valve are pipes

gate valve onto the pipe before setting the concrete. In order
to remove the valve I would have to twist a pipe. Their seems
to be no way to twist the pipes. What's a practical way to
remove the gate valve and install a ball valve in in cases
like this?

Thanks












Hi,
I'd cut and splice.
Much quicker.

Yep.
If you can't cut and then remove both ends and refit with the new
valve (you might have to insert a union) you can either rethread the
cut ends or use a 'Dressler' couplings (not sure of spelling but any
plumber will recognize that). They fit loosely over the pipe and have
two screw caps that tighten down gaskets for sealing.
