Do the WFE-3 and WFE-24 have the same pump curve?

A  Answered on 7/2/2009 by InyoPools Product Specialist Patrick P.

The WFE-24 and WFE-3 have the exact same pump curve. You may read more about full rate and up rate pumps here > and you may view or purchase either of these pumps here >

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.

How long can we expect the motor to last? Installed 10/2013 making very loud noises (Not whispering) Poolman says to replace it!

A  Answered on 5/13/2015 by InyoPools Product Specialist Patrick P.

Normally a pool motor lasts in the 7-10 year range, if it is running very loud then this means the bearings are going bad and it would be a good idea to replace the motor.

I have an existing WF-23. Should I replace it with the same unit or should I use the WFE-3? Are all of the connections compatible?

A  Answered on 6/25/2015 by InyoPools Product Specialist Hector F.

By going to the WF-3 you would be getting a full rate model which is technicaly a total horse power of just under 1. Connections are the same but you need to make sure that the filter will be compatible via flow rate to handle the extra water pressure.

How many GPM ( Gallons Per Minute ) is this pump ?

A  Answered on 7/18/2015 by InyoPools Product Specialist Brian M.

Depending on the head resistance, that number will vary. But at minimal head, the max would be 98GPM .
