CHANGING A CARTRIDGE FILTER

A cartridge filter needs to be changed when you notice a pressure drop, or 3 times per year if no pressure drop is noted. Color alone does not necessarily signify the cartridge needs changing.

1.  Turn off the water before and after the filter. Note: A ball valve is in the off position when the handle is perpendicular to the pipe it is on.

2.  You will need to depressurize the plumbing before opening the cartridge. If a faucet has been installed next to your filter, hold a bucket under the faucet and open the faucet; the water should stop shortly. If no faucet is present, press the red button on top of the filter to depressurize.  

3.  Have a bucket handy; place or hold it underneath the filter if possible. Using the wrench supplied, turn the clear plastic or blue holder (the “sump”) right to left, which is clockwise (facing top view down), 1-2 turns. Unscrew the remainder by hand.

4.  Drain the sump and replace the cartridge, adding one teaspoon of chlorine bleach (unscented Clorox) to the sump.

5.  Screw the holder back on, making sure the “O” ring is in place, and hand tighten. Follow up with a half turn or turn with the wrench, but do not over tighten.

6.  Turn on the water slowly on the incoming side to fill the filter. A leak at this stage indicates either a missing “O” ring or some grit or sand along the edge of the housing or “O” ring.

7.  Turn on the water on the outgoing side. 

8.  Any questions or concerns, call!
