Profitec Pro 300: Vacuum Breaker Replacement

Below are written and photographic instructions that will help you to remove and replace the vacuum breaker in your Pro 300.

  • adjustable wrench x2

    Profitec Pro 300 panel removal instructions

    With the top panel removed, you will want to identify the vacuum breaker. It can be easily located by finding the pressure stat first. The pressure stat will screw into the top of your Pro 300's vacuum breaker. 

    VACUUMBREAKER1

Remove the two spade connections that are attached to the pressure stat pins. 

VACUUMBREAKER2

Remove the rubber tubes from the left and right sides of the vacuum breaker. 

VACUUMBREAKER3

Using an adjustable wrench or 18mm crescent wrench, loosen the pressure stat from the vacuum breaker. Once the pressure stat has been loosened, you will be able to remove it with ease. 

VACUUMBREAKER4

With two adjustable wrenches, stabilize the t-fitting that the vacuum breaker is screwed into. Using the other wrench, loosen the vacuum breaker by turning it counter-clockwise. 

VACUUMBREAKER5

Once the vacuum breaker has been removed, you will want to thoroughly wrap the new vacuum breaker with teflon plumbers tape. Be sure to also wrap the threads of the pressure stat. Work backward alongside the instructions to install the new part.
