Installation Guide

Do Not Use with PEX
Liquid-based leak detectors, adhesive tape, pipe dope, linseed oil, threading compound, putty, mineral oil, petroleum products, metal pipe hangers.
Leave Excess Tubing
Leave extra tubing at the beginning and end of runs to simplify connection to manifolds and end points and to make connections without straining the tubing or
connection. Immediate connection to a manifold or transition ttings and then making the run reduces the chance of cutting tubing too short.
Identify Tubing Runs
Clearly and permanently mark each run at each end to identify the xture it supplies (hot or cold water, bathroom sink, kitchen sink, basement toilet, etc). Do not apply
adhesive labels to PEX pipe.
Thermal Expansion
Because PEX tube expands and contracts at about 1" per 100' of pipe for every 10°F change in temperature you must allow for expansion and contraction in long runs.
This can be accomplished with an oset or expansion loop.
PEX and Concrete
Tubing installed within or under concrete slabs should be continuous lengths of PEX tube. Do not install ttings beneath concrete.
Minimum Bend Radius
Do not bend tube too tightly. The minimum recommended bend radius is six times the tube size (i.e. ½" tube = 3" bend radius). When making a 90° turn, use bend
supports.
Pipe Hangers
Plastic hangers are recommended for use with Apollo PEX tubing. To prevent noise transfer, only use hangers that keep the tube o of the nailing surface. Hangers
should be used every 32" on horizontal runs and every 4' on vertical runs. Allow the tube to dip between hangers and never over tighten. To prevent stress on the crimp
joints, always support tubing before and after the tting.
Tube Through Studs
Grommets should be used when running tubing through studs to prevent damage and reduce noise transfer. Tubing that is run within 2" of a stud
nailing surface must be protected with a metal stud guard.
Stubouts
A copper stubout may be used to exit a branch from a wall. If a stubout is used, take care not to rotate the connection when cutting the end o. Always check local codes
on the use of copper stubouts.
Trenching
If PEX tubing is placed in a trench, leave sucient excess to allow for expansion and contraction when temperatures change in the
tubing.
PEX Tubing at Expansion Joints
Add a protective layer of insulation or place the tubing into the material underneath if installing PEX tubing under expansion joints.
