Clean your cartridge filters in half the time and with half the water using a uniquely designed Filter Flosser. Filter Flosser is constructed of 100% durable aluminum and works with a standard garden hose. The curved nozzle design provides extended cleaning area coverage and high pressure water to reach deep down between pleats. This guide shows you how to clean your cartridge using this economical and time saving tool.
Next you will have to relieve the pressure that has built up in the filter. Note the pressure on the pressure gauge. It will typically read between 15 - 20 psi. To relieve pressure turn the air relief valve on top of the filter counter clockwise. Water will spray out initially as you see the pressure on the pressure gauge go to 0 psi.
When replacing the filter top, watch that the O-ring doesn't bulge out of its grove. This becomes more of a problem as the O-ring becomes older and stretches. If the O-ring is not set properly the top will not close correctly and water will spray out when the pump is restarted. The O-ring should be replaced if this is a recurring problem.
