Installation Instructions

The Watts Governor 80-M1 is for both existing
and new installations providing an auxiliary relief
feature, a safe antisiphon vacuum breaker and
truly dependable fill valve assembly.

The non-adjustable thermal expansion relief valve
is set standardly at 80psi (552 kPa), 100psi (6.9
bar), or 125psi (8.6 bar) with a maximum operat­ing temperature of 110°F (135ºC) to meet existing
codes. The Watts Governor 80 is available in three

maximum water level mark is even with or
above the top of the overflow tube.

Important: This is a control device that limits

system pressure in the event of thermal expansion.
It does not take the place of any safety relief
devices that are required by code. If the incom­ing water pressure exceeds 65psi (448 kPa), a
pressure reducing valve must be installed at the
service entrance. If the system already contains a
pressure reducing valve, be sure it is set no higher
than 65psi (448 kPa) under a no-flow condition.
