Q. I need help in installing my gas dryer that has been converted for propane. I was wondering what type of pipe I need to run so I could get the propane to the dryer? Also, do I need a pipe threaded or do they come in certain lengths already threaded?

A. Whatever type of pipe is presently being used in the house can be used to run to the dryer location. The pipe diameter for natural gas is usually half inch. Use half inch not more than six feet back from the dryer. All the rest back from that point to the supply pipe would be ¾-inch, which may or may not apply for propane. Codes vary from state to state and local area to area. It's best to check with a professional plumber in the area or the building department in your locality. A propane supplier may also know.

Building materials and local privately owned hardware stores would also have the materials needed. Pipe comes in many size lengths and is already pre-threaded. You'll also need supports to secure pipe to walls, beams or studs, whichever is the case. You will also need a shut off valve at the end of the run and dryer connection fittings and parts.
