Model Governor™80M2

Toilet Fill Valve and Thermal Expansion Relief Valve

Size: 8 ¾" to 12 ¾" (222 to 324mm)

The Governor™80M2 is a feature rich universal toilet tank fill valve designed to protect plumbing systems and to conserve water. As a fill valve, it is able to detect a leaking toilet flapper and to prevent the tank from continuously refilling until a repair is made. The override feature enables the toilet to continue to be used until the flapper can be replaced.

The Governor™80M2 is also a thermal expansion pressure relief valve limiting supply line pressure and protecting plumbing from the damaging effects of pressure surges due to thermal expansion. The Governor™80M2’s water conservation feature helps to eliminate the “overfill” condition present with traditional toilet fill valves. The adjustable flow control on the primer tube allows the tank to fill to the appropriate level without overfilling. The Governor™80M2 also acts as an anti-siphon backflow preventer keeping tank water from backing up into the potable water supply.
