Installing Uponor AquaPEX Tubing During Ground Work

• Properly secure tubing at intervals

necessary to keep the tubing from

floating up during the pour.

• When installing fittings for in-slab

applications, use only EP fittings. For

under-slab applications, use EP, Red

Brass, Lead Free or DZR Brass

ProPEX fittings.

• When passing through a concrete slab,

ensure tubing is protected and allows

for movement, including expansion

and contraction of tubing. Minimum

wall thickness of protective material

shall be 0.025" (0.64mm). Approved

protective material includes HDPE

wrapping, closed-cell pipe insulation,

PVC elbows and sleeves or equivalent.

Ensure proper tubing placement when

exiting the slab.

• Maintain pressure on tubing installed

in a slab during the pour to facilitate

leak detection.

• If the tubing will be exposed to

sunlight for more than 30 days, sleeve

the tubing to protect against damage.

• If the tubing runs through an

expansion joint, protect with a sleeve

or dip below the joint. See Figures

5-1 and 5-2.

Caution: Uponor recommends using a ProPEX EP coupling to repair

tubing damaged during a concrete pour. If a ProPEX EP coupling is not

available, you can use a ProPEX brass coupling wrapped with a protective

polyethylene sleeve to prevent direct contact between the concrete and

the brass coupling.
