Product details

This is the Jacuzzi replacement DE filter grid, part number 42357004R, measuring 12 in long by 7 in wide. Two of this size are used in the filter, within a complete set of six grids.

Which filters it is listed for

The part is specified for the Jacuzzi Landslide LS40 and the Jacuzzi Avalanche AV40. It is also cataloged under the broader Jacuzzi Avalanche AV-40 through AV-100 and Landslide LS40 through LS70 parts groups, so check your exact filter model and grid count against it before ordering.

What the grid does

A DE filter works by holding a coat of diatomaceous earth on the fabric of its grids. That coat is the actual filter medium, and the grid is what carries it. When the fabric tears or thins, DE passes straight through to the pool and the filter stops holding pressure the way it should.

Replacing them

Grids in one tank are the same age and have done the same work, so a single torn grid rarely means the rest are healthy. With the tank open it costs nothing to look over every grid, and doing the set at once saves a second teardown a season later.

Questions and answers

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

How many of these does my filter take?
Two. The full grid set is six, and two of them are this 7 in by 12 in size.
Which filters does it fit?
It is specified for the Jacuzzi Landslide LS40 and the Jacuzzi Avalanche AV40. It is also cataloged under the wider Avalanche AV-40 to AV-100 and Landslide LS40 to LS70 parts groups, so confirm your exact model before ordering.
What size is the grid?
12 in long by 7 in wide.
Should I replace one grid or the whole set?
Grids in a filter are the same age and see the same duty. If one has torn or the fabric has gone thin, expect the others to be near the end as well, and check them all while the tank is open.
