Product details

The Pentair 178583 is the genuine air bleed tube assembly for the Clean and Clear 520 cartridge filter and the Quad D.E. 100. It is the current version of the part and replaces all of the earlier air bleed assemblies used on those filters.

Superseded design

The version this replaces had a white cap that looked very similar to the pipe it was attached to, and it is no longer produced. If that is what is on your filter, this assembly is the correct replacement.

What it does

Every time the pump starts, air collects at the top of the filter tank. The bleed assembly gives that air a path out so the tank fills with water. Trapped air keeps part of the element dry, drops effective filter area, and can make the tank pressure readings misleading. A cracked or blocked bleed tube is worth changing rather than working around.

Questions and answers

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

Which filters does this fit?
The Pentair Clean and Clear 520 and the Quad D.E. 100.
My old one has a white cap. Is this the same part?
The older assembly used a white cap that closely matched the pipe it attached to, and it is no longer available. This current version replaces it and every earlier air bleed assembly for these filters.
What does the air bleed assembly do?
It vents the air trapped in the top of the filter tank so water can fill it completely. Without it, air pockets stay in the tank and the filter never runs at full capacity.
Is it a genuine Pentair part?
Yes. It is the Pentair OEM assembly, part number 178583.
