OPERATION INSTRUCTIONS
NOISE AND WATER HAMMER IN PEX SYSTEMS
As with all plumbing materials under some operating conditions, water hammer can occur in PEX
plumbing systems. The inherent exibility of PEX drastically reduces the magnitude of pressure
surges compared with metallic plumbing materials. Damage to plumbing components in a PEX
system due to these pressure surges is highly unlikely, although noise can sometimes result.
Fortunately, there are solutions to minimize or eliminate water hammer noise.
Clamping or strapping more frequently may help prevent tubing noise. It is very important that the
tubing not be in contact with wallboard, forced air ducts or other high resonance articles. Insufciently
Insufciently or improperly clamped or strapped tubing may move during xture operation and hit
against these surfaces.
Install a water hammer arrester on xtures where noise is a problem. A water hammer arrester
installed within 6 ft. of the xture on the cold water side only will eliminate the source of the noise
(the pressure wave). It should be noted that even with an arrester, tubing that is clamped or strapped
insufciently may still hit against something as it moves slightly when the water ow is stopped.
Avoid operating xtures in such a way that causes near instantaneous shut off. Simply closing xtures
in a less abrupt manner can eliminate hammer noise.
CARE AND MAINTENANCE
TROUBLESHOOTING
• To protect and maintain the nish, clean only with a soft, damp cloth.
• Do not use a detergent or cleanser that may harm the nish.
PROBLEM POSSIBLE CAUSE CORRECTIVE ACTION
Leak from under handle. Retainer nut has come loose.
O-ring on cartridge is dirty or
damaged.
Tighten the retainer nut. Clean
or replace O-ring.
Water will not shut off
completely.
Rubber valve seat is dirty or
broken.
Remove handle and cartridge to
check rubber valve seat. Clean
or replace it.
