Hayward d.e.pool filter lid stuck
Open all air & drain valves, if multi-port valve - place in "Winter" mode. If push pull type valve place between positions. This will relieve any siphon & pressure in the filter tank. After clamp is removed, use a screwdriver or other "Firm" type of pry bar (2 or more would be better) and then begin to carefully pry it off or apart.
If this does not help. then there is another way to do this,
BUT IT IS NOT RECOMMENDED IF YOU ARE NOT GOING TO BE VERY AWARE OF THE POSSIBLE DANGER!!! IF THE PUMP ON OFF SWITCH IS NEAR THE FILTER - DO NOT TRY THIS!!!
At times the filter tends to weld themselves together and it is very difficult to remove (like what you posted - stuck lid) due to excess greases, Vaseline is the main culprit, never use Vaseline on orings - it makes them swell. Use a Silicone or Teflon based Lubricant! And the o-ring is swollen in most cases for these types of problems and need to be replaced.
Anyway, with filter valves back in filter, waste, or backwash mode, Air relief valves wide open & drain cap/plug removed from filter, and the clamp is off, Quickly and consecutively - turn pump on and then off, On and then off. The water pressure will pop the lid off the tank. As you can tell, this can be dangerous as the filter tank will become pressurized and if you leave the pump on for too long (more than a couple of seconds) that lid will fly off that tank at a high rate of velocity with very possible Dangerous circumstances.
STAY CLEAR IF ATTEMPTING THIS! AND DO NOT LEAVE PUMP ON FOR MORE THAN A SECOND AT A TIME.
Be very careful and good luck.
