Product details

The Hayward ECX27091 is the back mount pressure gauge used across the Hayward filter range. The stem leaves the back of the gauge rather than the side, which is how Hayward mounts it on many of its filter heads and air relief assemblies.

Why the gauge matters

Filter pressure is the cheapest reading you have of how dirty the media is. Note the pressure with a clean filter, then clean or backwash once it has climbed well above that. A gauge that sits at zero, sticks, or has fogged over tells you nothing, and filters routinely get run far too long behind a dead one.

Fitment

Hayward lists this gauge for SwimClear and Star-Clear cartridge filters, the Easy-Clear range, Pro-Grid and Regen X DE filters and the Perflex DE filters. Where a port will not take the gauge directly, a threaded adapter for the pressure gauge is available as a separate part.

Questions and answers

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

What does back mount mean?
The gauge stem comes out of the back of the gauge instead of the side, so it threads straight into a port facing you rather than one below it.
Which Hayward filters does it fit?
SwimClear and Star-Clear cartridge filters, the Easy-Clear range, Pro-Grid and Regen X DE filters, and the Perflex DE filters. The fits list carries the model numbers.
Is an adapter included?
No. The threaded adapter for the pressure gauge is a separate part, needed only where the port will not take the gauge directly.
When should I clean the filter?
Note the pressure with a freshly cleaned filter. When the gauge reads well above that starting figure, it is time to backwash or clean the elements.
