I have a "Pentair Clean and Clear Cartridge Filter". (I don't know why it's called a "filter" instead of a "pump" or "cartridge filter pump". That's the word used in the Owners Manual.)
In the manual, there is this WARNING. Everything is in capital letters, due to it being a warning, so I'll type it in capital letters.
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE CIRCULATING SYSTEM (e.g., LOCK RING, PUMP, FILTER, VALVES, ETC.) IS SERVICED, AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED. PRESSURIZED AIR CAN CAUSE THE LID TO BLOW OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH OR PROPERTY DAMAGE. TO AVOID THIS POTENTIAL HAZARD, FOLLOW THESE INSTRUCTIONS.
I'm in a rental. It appears that the Lock Ring had previously blown off prior to my occupancy and doesn't assemble very easily. I just purchased a new one, but my question is this:
Does everyone in this forum use a pump with a similar warning? If I ever install my own pool, I'd rather use a pump that doesn't have the potential to cause "severe injury, death or property damage"! Does such a pump exist?
Aren't there simpler and safer pumps than this model???
