How often should the grids be replaced & how can I tell if they need replacing? Our grids keep clogging and I was told it may be because they are worn. Is this true? Thanks! Kelly

Hi Kelly, On average you will want to replace your Grids every 4-6 years. You will want to backwash weekly as well as take them out once a year and clean them. You can tell if there going bad if you get DE powder in your pool as well as after you clean them and backwash the filter and the pressure goes above 20-25 psi.
