Product Identity

The Watts 1 LF 008PCQT-1 is a lead-free brass anti-siphon backflow preventer sized for one-inch IPS connections. It serves residential and light-commercial plumbing systems that require cross-connection control at the fixture level. Installers and facility managers use it to stop contaminated water from reversing into the potable supply.

Thermal Pressure Limits

The valve operates continuously between 33 and 180 degrees Fahrenheit with a maximum pressure rating of 150 psi. Its spill-resistant construction limits discharge during normal pressure fluctuations, reducing cleanup and water waste. The brass body maintains structural integrity across the full temperature range without deforming.

Standards And Compliance

Approval by the Foundation for Cross-Connection Control and Hydraulic Research at USC and IAPMO listing confirm the device meets recognised backflow-prevention criteria. These certifications satisfy most local inspection requirements for potable-water protection. The lead-free alloy also supports compliance with modern drinking-water safety regulations.

Questions about this item

How do I install the 1 in IPS connection on the Watts 008 backflow preventer, and what step is often missed?

Thread the 1 in IPS ends into the piping using lead-free brass compatible sealant; the step often missed is orienting the spill-resistant vent downward so it can drain properly.

What maintenance will the lead-free brass body and spill-resistant vent need over time?

Inspect the vent annually for debris and verify the internal check valve moves freely; replace the unit if the brass shows corrosion or the vent no longer seals at 150 psi.

At what pressure or temperature limit does the Watts 008 show stress first during sustained use?

The 150 psi maximum pressure rating is typically reached before the 180 °F temperature limit in continuous operation.
