what should i replace my galvanized water supply pipes with?

Hi JMcoomer,

For underground plumbing I would recommend copper pipe as it is trouble free, won't rust and is easier to work with than galvanized pipe.

For any above ground plumbing I would recommend Pex tubing and Shark-Bite fittings. These are push on fittings

so no soldering is required.

You can plumb all of your hot and cold water system, using just the fittings and a tubing cutter. No wrenches or a torch is required.

You can buy the Pex tubing and the Shark-Bite fittings at your local Home Depot.

Mike,
