I was wondering how do you know if you need a new grid? Mine is about ten yrs old. The problem i'm having is on start up its blowing DE back into the pool what can cause this because other than the grid and the o ring on the lid their is noting to this filter.

Hi Kim, it would definitely be time for a new grid, normally we see the life span being 3 years or so. To determine when it is time to replace your DE grid you will want to note your initial clean starting PSI from your pressure gauge, when you install your new clean DE grid. You will know it is time to replace your grid when after you clean your grid the pressure does not drop below 10 PSI above your initial clean starting PSI. For example if the initial clean pressure reading is 10 PSI and 3 years from now you clean your grid and it does not drop below 20 PSI then it is time to replace your grid. Another tell tale sign that the grid needs to be replaced is when DE is returning back to your pool.

Dose this grid fit the Hayward serial #340h29 regenx

A  Answered on 8/12/2015 by InyoPools Product Specialist Lennox H.

Hi Walter, You would have to call Hayward Tech Support at 908.355.7995, their the only ones that can tell you which replacement cartridge you need from the serial number. You can also find out which cartridge you by measuring the current cartridge and comparing it to the RG450 Regenx Grid and the RG700 and SC700 Regenx Grid.
