Flexible Tubing

What a Do-It-Yourselfer Should Know About Flexible Tubing

Flexible tubing is inexpensive, easy to cut and install. It is especially easy to work with in cramped places because it is flexible without a lot of fittings.

Two kinds of flexible tubing are offered: Vinyl and Polyethylene. Combined, they have literally hundreds of uses. Applications include water supply lines, air conditioner drains, boat pumps, swimming pools and many more.

When installing flexible tubing, simply make any required cut with a utility knife. With the proper fitting connection, flexible tubing can then be securely attached to the same or a different tubing material.


Before beginning to work on supply lines, turn off the water supply at the main shutoff valve. Then drain the pipes by opening a faucet a the lowest level in the building.

Support horizontal runs of flexible plastic supply tubing every 6 to 8 feet, vertical runs every 8 to 10 feet.
