Diaphragm pumps are long lasting. But they are sensitive to debris. Debris will reduce or choke off water flow. It is critical to clear the filter periodically.
We use both the quick-connect filters and threaded filters. You can take out the mesh screens without removing the filter cartridge from the pump.
For the quick-connect type
Use both thumbs to squeeze the tabs towards the middle
While holding the tabs, use your index fingers to lift up the cap
After cleanning the mesh screen, push it all the way down into the cartridge housing
until you hear 2 clicks. Failure to do so will lead to either air leaks or leave a gap at
the filter bottom to allow the debris to escape to the pump
The screw-on type filter is simple: twist off the clear cap, and pull the mesh screen out
