Optional Plumbing Procedures

This section provides information on plumbing with copper fittings and with plastic pipe.

Hard Plumbing the Bypass With Copper Fittings

Do not use Qest fittings for hard plumbing with copper fittings. When preparing the male threaded fittings of the

I/O adapter, use the following guidelines to avoid damage to the plastic pipe threads.

A. Wrap the threads three times with 1/2-in. wide Teflon tape. Place each consecutive wrap on top of the

previous wrap.

B. To prevent tearing of the tape, use Teflon paste on the first two male threads only. The paste lubricates

the tape and fills the small void areas that might exist between the threads. When the joint is complete,

there will be a small bead of sealant at the fitting interface, which indicates a properly joined

connection.

C. Use a union with a threaded connection to facilitate repair of potential leaks in soldered joints.

D. Prepare the copper tail assemblies in advance to enable them to cool prior to final assembly. Advance

preparation and cooling will prevent heat damage to the plastic pipe threads of the adapter.

E. Ensure that the copper tube is at least 10 cm (4 in.) long.

F. Turn the fitting counterclockwise until you feel the threads engage and then tighten to prevent cross

threading. Do NOT overtighten the fittings.

Caution: Do NOT allow heat from the torch to transfer to the plastic valve component, which

could be damaged.
