That pump doesn't have a pressure switch! It has a digital flow sensor on discharge. It will keep running so long as there is a flow. Usually caused by dripping tap, or leak. Pressure doesn't stop the pump. By the way - Don't expect to get parts from Canadian Tire or Mastercraft - They told me that they carry NO parts for that pump. It is very similar to a Burcam pump and they may have parts or offer service.

SOURCE: why wont my Jet pump shut off?

Is the little pipe that connects to the pressure switch clear?

I suggest you remove it and blow through it to make sure it is clear. If the pressure is getting to the switch, it has to shut off ... your switch should be set around 30/50 (on at 30 - off at 50)

Finding a replacement seal for mastercraft water pump model 312242
Above answer is talking about an automotive water pump. This is a jet pump for home cottage water supply. Canadian Tire do not stock parts for any of their Mastercraft pumps. I found that out the hard way! For a seal, you may be able to find a generic one. A company that repairs other makes of domestic water pumps may have one that will fit.

My mastercraft jet pump ran dry and will not pump what am I looking for to fix it?
Hi Nick:
Just for fun, try priming it. Remove the Pupe plug with the square head, fill it with water, screw the plug back in, and give it a try.

Mastercraft jet pump
Mastercraft makes sells a lot of pumps. You might want to post with the model number etc. You can also go on line and probably get the manual that will show how it is done.
