window cleaning pump controllers

Window cleaning pump controllers, are an important part of the setup. The controller controls the flow of the water that comes out of the water fed pole. You can turn the water flow up or down depending on the type of job that your on.

There are many different controllers, the really cheap diy ones just turn the water flow up or down. The more expensive ones, have uses such as slit relays, and dead end detection.

If you don’t use one then your pump will be running at the highest rate and will end up burning your pump out. So don’t try to save a bit of money by not buying one as it will end up costing you more in the long run.
