PEX
Temperature and Sunlight
Keep PEX tube away from extreme temperatures - 12" away from recessed lighting and 6" away from gas vents. Also, keep away from attics, crawl spaces, outside walls,
or insulate per plumbing codes. Keep out of direct sunlight.
Excessive Pressure and Temperature
Apollo PEX tubing is rated up to 160 psi at 73° F or 100 psi at 180° F. Exceeding these ratings will void the warranty.
Excessive Heat
Soldering - Do not solder near Apollo PEX tubing.
Water Heaters and Boilers - Use a minimum of 18" of metal tubing to transition between Apollo PEX tubing and the water heater/boiler.
Freeze Protection
Apollo PEX is resistant to freeze damage, but freeze protection is recommended that is typical to the area where installing. Fittings and connections can be damaged if
the plumbing system freezes.
Thawing a Frozen System
Do not send electrical currents through a PEX plumbing system. Do not use an open flame to thaw a PEX plumbing system. A hot air gun may be used as long as the
temperature does not exceed 300°F (149°C). Do not use a hot air gun on one spot for more than five minutes at a time. Do not heat pipe until it changes color.
Damaged Pipe
Do not splice PEX pipe in inaccessible locations. If a splice is necessary at a point underground, insulate the coupling and splice point to protect it from corrosion and
stress. Always perform a leak and pressure test after making a splice.
Bundling Lines
Run hot and cold lines in separate groups to avoid transferring heat between hot and cold lines.
Inspection
Always inspect PEX tubing for damage and proper fastening prior to testing. Also, check all fitting and manifold connections. Repair or replace as needed. Pressure test
the system with air or water at completion.
Expansion Loops
PEX tubing expands and contracts approximately 1" per 100' of tubing
for every 10°F change in temperature. Because of this expansion and
contraction, expansion loops should be installed to compensate for these
changes without damage to the plumbing system. When creating an
expansion loop, make sure there is adequate space for the loop to expand
and contract. Do not install the loop so it’s touching studs or joists on both
sides. These loops will expand when the pipe is heated and contract when
the pipe cools or the building is unheated.
