Things to Check Before You Call For Service
If you unexpectedly experience a change in the quality of your water, make these simple checks before calling your
Culligan deal er� One of the following conditions may be the reason for the change�
Bypass Valves
Check to see if they are in the proper position� Cul-Flo-Valv® Bypass, if used, should be in the "Service Position"
(handle stem screwed out) position� If hand valves are used, see that inlet and outlet valve are opened and that the
bypass valve is closed�
No Water
If you aren’t getting any water flow at all, make sure your water supply is work ing� Open a tap ahead of the filter
(outside tap) to see if you have any water pressure� If you have water pressure, check the bypass valve� If it is in the
Service position, put it into the bypass position and call your Culligan dealer for service�
If You Have A Cartridge Filter Installed
If your system has a cartridge type filter installed prior to the Aquasential PFAS Filter System make sure the cartridge
is not clogged as this can result in low water pressure� Replace the filter cartridge with a new one and check to see
if water pressure returns�
