IM-PF 724596 1021 PureFlow Water System (EN)
WARNING!
PRESSURES USED IN TESTING CAN BLOW UNMADE
OR INCOMPLETE CONNECTIONS APART WITH
TREMENDOUS FORCE!
If such a solution is used, the antifreeze solution must
be su󶈷ciently concentrated to withstand the lowest
temperature encountered while the testing 󶈶uid is in the
system. Antifreeze solutions should be purged and the
system 󶈶ushed with potable water prior to consumer use.
This force is many times greater when air is used as a test medium.
To reduce the risk of personal injury, ensure that all connections are
completed before testing. Use only the pressure and time required to
determine that the system is leak free.

* If the pressure in the system declines more than 8 psi during the 15-minute to one-hour
period, re-pressurize the system to the original test pressure and retest. If the system pressure
declines more than 8 psi again during the test period, test the distribution line test caps or any
other 󶈵ttings in the system with the approved leak-detect solution.
Note: Some plumbing 󶈵xtures may not withstand test pressures greater than 80 psi. Consult
󶈵xture manufacturer’s instructions for pressure limitations or plug all distribution lines at the
󶈵xture end. The system shall, at a minimum, withstand the test pressure, without leaking, for a
period of 15 minutes.
WARNING!
Water testing shall be avoided during freezing conditions.
Under NO circumstances shall the system be tested at
temperatures lower than 10˚F (-12˚C).
WARNING!
FOLLOW ANTIFREEZE MANUFACTURER’S
INSTRUCTIONS FOR CONCENTRATIONS. Use only
nontoxic antifreeze approved for drinking water systems.
