Replace gasket. 4. Tighten bolts. Hard bumping. D.E. leaking back to pool via skimmer or main drain. 1. Caking of D.E. under tube sheet. Sometimes caused by accumulation of sun tan oils, hair or floating particles that bind together in a clay-like form. 2. Overloaded with D.E. Sometimes happens when last charge of dirty D.E. was not properly drained. 3. Filter runs too long between bumping. Filter check valve worn or stuck open. 1. Bump-Drain-Recharge more often and reduce the use of oils. 2. Bump-Drain-Recharge with proper amount of D.E. 3. Bump more frequently. Clean and/or replace. Very short cycles when vacuuming. Normal if pool contains: 1. Very dirty water. 2. Presence of live, vigorously growing algae. 3. Presence of alum or floccing agents, which will clog filter. 1. Bump-Drain-Recharge more often. 2. Add enough chlorine to control this growth - then vacuum. 3. Vacuum so as to by-pass filter. Avoid using floccing agents.
