Universal Suction Relief Valve Kit

The Suction Relief Valve Kit is used to prevent damage to a central vacuum unit due to blockages. When the central vacuum system has a clog or blockage, the suction relief valve opens. This keeps air flow open to the motor, which prevents the motor from burning up.

This kit fits all central vacuum systems with 2" outside diameter pipe. The kit includes a Sweep Tee fitting and the Relief Valve.  They are installed into the intake side of the central vacuum, right before the pipe that goes into the central vacuum unit.
