Disinfecting the Piping System with Chlorine:
1.
Shut off the water to the inlet and outlet of the cartridge filter.
2.
Remove the cartridge sump and empty all water. Fill with household chlorine (Clorox, non-
scented), 5.25% sodium hypochlorite.
3.
Re-install the sump to the filter assembly and open the inlet and outlet valves.
4.
Open the cold water faucet at the farthest point in the piping until you detect chlorine odor.
Once the odor is detected, close that faucet. Continue this procedure until the chlorine odor
has been detected at every faucet. If chlorine odor is not detected at all faucets, repeat
steps 1 through 4.
5.
Close ball valve on outlet of cartridge filter.
6.
Allow the water to stand for at least (4) hours to kill the bacteria residual in the piping
system.
**
No water should be used during disinfection. **
Before consumption of water, an EPA Lab Test is suggested.
