Product details

This is the Pentair 355305Z pump base, listed for the WaterFall, Challenger High Flow and Challenger Pressure pool pumps. It also appears under the number 355305.

What the base does

The base is the piece the pump sits on and bolts down through. It sets the pump at the right height so the suction and discharge line up with the plumbing that was cut for them, and it holds everything square while the motor runs.

When to replace it

Bases crack from vibration, from freeze damage and from being levered around during a motor change. Once one is broken the pump no longer sits level, and the load it should be carrying goes into the unions and the pipe. A new base is a small part next to the leak that follows.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pumps is this base for?
The Pentair WaterFall, Challenger High Flow and Challenger Pressure pumps.
Is 355305 the same part?
Yes. The base is listed as both 355305 and 355305Z.
Does it include the motor or the pump?
No. This is the base alone.
Why does a cracked base matter?
The base holds the pump level and square to its plumbing. Once it cracks, the weight starts going through the unions and the pipe instead, and that is where the next leak shows up.
