The LF05 Water Hammer Arrestors are designed to eliminate
water hammer. The LF05 features Lead Free* construction to
comply with Lead Free* requirements.
Dishwashers, clothes washers, fast closing positive shutoff
valves incorporated in the plumbing system all contribute to
creating water hammer which is not only annoying but damag-
ing to pipes and appliances. Series LF05 water hammer arres-
tors provide economical and effective single fixture protection
from the destructive and annoying problem of water pressure
shock. Utilizing piston style construction, factory charged and
sealed, the Series LF05 provides automatic, repetitive control
of water hammer when properly installed.
