What to look for in a de filter?
Some DE filters, like the Hayward Perflex, have “fingers” instead of grids. These tube-like tentacles can also crack and require replacement. Other parts to look at while you check the tubes are the bump shaft o-rings, diaphragm gasket, the top and bottom tube sheets, or possibly loose tube sheet bolts.
What should I do if my filter gauge reads zero?
If the filter pressure gauge reads zero or close to zero with the pump running and the valve in filter or backwash mode, something is wrong. Give the gauge face a flick – with your fingernail to see if it pops up. Inspect the gauge dial or face for warping, which can prevent the dial from moving.
How can I tell if my de filter has a crack?
When you check the grids, also take a glance at the plastic collars where they attach to the manifold. Even though the grid fabric might be intact, a crack in this small part would mean the entire grid needs to be replaced – sorry! Some DE filters, like the Hayward Perflex, have “fingers” instead of grids.
What happens when a Jandy filter gets pressurized?
When any part of the circulating system, i.e., filter, pump, valve(s), clamp, etc. is serviced, air can enter the system and become pressurized when the system is restarted. Pressurized air can cause product failure or also cause the filter lid to be blown off which can result in death, serious personal injury or property damage.

Is it bad to run de filter without de?
Or while running the DE filter without DE is a bad idea, would it not hurt the filter for a brief amount of time (2 hours)? Thanks for the advice! If the water was dirty, it’s probably worth opening it up and cleaning the grids. Otherwise it may just shorten your cleaning cycle.
What causes de filter powder to return to pool?
CHECK MULTIPORT VALVE GASKET – If your Multiport Valve (MPV) Spider Gasket is damaged, you could have DE Powder leaking into the FILTER path during BACKWASH. A common cause of a damaged MPV gasket is the pool owner’s failure to turn off the pump before moving the MPV handle.
