INSTALLING FLEXIBLE TUBING

The hot- and cold-water flexible water supply connections are from the shutoff valves to the threaded end of each faucet. The flexible tube comes in several lengths and is made of chrome-plated copper. The tubes are bent to fit and attached with coupling nuts.

Bending flexible tubing. Use the following steps to bend flexible tubing (see Figure 15):

FIGURE 15. BENDING FLEXIBLE TUBING

1. Slide the flexible tubing into the correct spring bender.
2. Place both hands on the spring bender, and apply pressure until it is bent as you want it.

NOTE:  Spring benders come in a set with several diameter sizes.26

Installing the flexible tube connector for water service. Use the following steps to install the flexible tube connector (see Figure 16):

FIGURE 16. INSTALLING FLEXIBLE TUBING

1. Slide coupling nut onto tube up to the bayonet head.
2. Screw coupling nut hand-tight onto faucet threads, and tighten with a basin wrench.
3. Slide coupling nut and compression ring onto the lower end of tube, and place tube into shutoff valve.
4. Screw coupling nut hand-tight onto valve, and tighten with a wrench.

NOTES:

1. This method of it installation is for both hot-water (left side) and cold-water (right side) water service lines.
2. If the tube is too long to connect to the shutoff valve, cut it to get a good fit.
