Plumbing Installation Guide
Uncoiling Zurn PEX Tubing
For ease of installation Zurn recommends using the Zurn PEX dual
coil uncoiler, QDISP; the Zurn PEX pipe dispenser, QHD; or the
Zurn PEX portable uncoiler, QPHU.
Zurn PEX straps and hangers hold pipe in position and prevent
strain on fittings when the pipe is bent.
Always strap
pipe down
before bending.
Vertical runs need support at every floor level.
Since Zurn PEX tubing expands or contracts one inch for every
100 feet of pipe for every 10° of temperature change, you must
allow for expan sion and contraction in long runs with a 12-inch
horizontal offset.
Clamps
Always cut the pipe longer than neces sary to allow some slack for any
contraction in the pipe. 1/8” per foot of length is usually enough.
Strapping support should be firm but loose enough to allow the pipe
to move back and forth as it expands and contracts.
12”
Clamps
Horizontal runs should be supported every 32 inches.

Supporting Zurn PEX Distribution Lines
Note:
Zurn PEX should be supported or strapped every 32” when
hung from floor joists or running across rafters. When supporting
tube bundles, use a strap to support the entire bundle.
Top Out Installation
Straps can be as far as 6 feet apart if the pipe is continuously
supported.
