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.

i repaired an olympic size pool of 50 feet by 84 feet by 4 feet deep. 34,500 gallons . pipe size 4 inches from Main Drains and Skimmers to pumps. Can a 3H.P: or two work to circulate the water ? Please respond as soon as possible as pool is full of water and needs to filter.

A  Answered on 4/14/2017 by InyoPools Product Specialist Scott W.

What is the distance from you main drains and skimmers to your pump so I can calculate the flow rate?
