Install the Diatrol on the supply piping as close as possible to the offending fixture(s). The

Diatrol should be installed upstream of any fast-acting valves. Use the guidelines below
to determine the best placement. Multiple fixtures and long supply lines may require the
installation of multiple Diatrol shock suppressors.

3. ADJUSTMENT

With the Diatrol empty of water, adjust the factory pre-charge to equal the average flow

pressure. For example: if the line pressure registers 65 psig with the fixtures open, adjust the
Diatrol air charge to 65 psig.

A professional plumber should check the complete system, including the Diatrol, yearly and

more frequently as the system ages.
