Pool systems use tank filters to clean the water circulating through them. A pool filter contains a medium, such as sand, that removes particles from the water. Over time, the medium in the filter loses its effectiveness and causes pressure to build in the tank. A pressure gauge installed on the filter makes it easy to monitor its condition, however, pressure gauges also age and become damaged by weather or mishandling and require replacement.
Things You'll Need
- Thread seal tape
Shut off the pool filter and pump motor at the switch or power box. If no switch or power box exists, shut off power to the system at the breaker box.
Unscrew the pressure gauge located on top of the filter neck. Unscrew the pressure gauge with pliers if it's stuck fast in the filter.
Wrap thread seal tape around the threads on the new pressure gauge. Screw the pressure gauge into the outlet on the filter neck by hand. Do not over-tighten the gauge or it might break.
Restore power to the pool system, then run the filter and pump. Check the area around the pressure gauge for leaks. Reapply thread seal tape to the threads if leaks exist.
Tips & Warnings
- Record the pressure gauge's reading just after you clean the filter. When the pressure becomes 8 to 10 lbs. higher than the clean reading, backwash and clean the filter.
