Product details

The CMP 25280-100-005 is the grate for the PowerClean Ultra and PowerClean Mini chlorine feeders. It is the genuine CMP replacement part.

What it does

The grate is the internal shelf inside the feeder body. Chlorine tablets stack on top of it, which keeps the bottom of the stack clear of the water that sits in the base of the housing. That gap is part of how the feeder controls dosing: water passes through at a rate the dial sets, rather than simply soaking the whole stack.

Why it wears out

Trichlor is hard on plastic, and the grate is in constant contact with it. After enough seasons the material goes brittle, then cracks or breaks apart. Once that happens the tablets slump into the base and the feeder starts dosing unevenly, which usually shows up as chlorine readings that swing rather than hold.

Before you order

Open the feeder and confirm which internal part has failed. The lid, the dial, the flow meter assembly and the drain plug are all separate CMP parts, and it is worth ordering everything that is tired in one go rather than shutting the system down twice.

Questions and answers

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

Does this fit the Mini as well as the Ultra?
Yes. CMP lists 25280-100-005 as the grate for both the PowerClean Ultra and the PowerClean Mini chlorine feeders.
What does the grate actually do?
It sits inside the feeder body and holds the tablet stack up, so the tabs are not simply sitting in the water pooled at the bottom of the housing.
Why do these break?
Constant contact with chlorine tablets is hard on plastic. Over enough seasons the grate goes brittle and starts to crack or crumble, and that is normally when it gets noticed.
Is it a genuine CMP part?
Yes. This is the CMP part number 25280-100-005, not a generic replacement.
