What is a booster pump, and where does it attach to?

A  Answered on 4/12/2009 by InyoPools Product Specialist Patrick P.

This cleaner is designated as a pressure side cleaner which means:Pressure Pool Cleaners most pressure cleaners require a booster pump which is typically a ¾ horse power pump that is dedicated for use with the cleaner alone. The booster pump allows you to operate the pressure cleaner without taking any suction away from your main pool pump. The addition of the booster pump does mean pressure cleaners require a more involved installation than either suction or robotic cleaners. The booster pump is installed in tandem with your pool pump.

I just finished replacing the shaft seal on my booster pump. As soon as I turned the pump on water was leaking from the shaft seal. Is it defective or am I doing something wrong?

A  Answered on 2/16/2012 by InyoPools Product Specialist Patrick P.

Depending on the model, the installation of a booster pump shaft seal can be slightly different than a pool pump shaft seal. Some booster pump and pool pump shaft seals require that a silicone sealant be used on the outer areas of the metal seat of the shaft seal. The seal will need to be lightly hammered into the body of the pump. You can use a 1 inch PVC coupling or a piece of 1 1/4 inch PVC pipe and a rubber mallet. This procedure will apply to any pool pump or booster pump using a >PS-1000 style shaft seal.
