What service does a D.E. (Diatomaceous Earth) filter need?
Diatomaceous Earth pool filters should be backwashed when the operating pressure rises 8 – 10 psi above the filters baseline pressure. D.E. filters should also be carefully disassembled and thoroughly cleaned every year (more often on pools with heavy usage; pets, parties, high foliage/debris levels, etc.). We inspect the grid fabric and structure, the manifold, the air relief screen, the tank clamp and o-ring, and the air relief assembly. Please refer to our Regular Maintenance page for pricing.
