Changing the sediment filter in a whole house well water filtration system. Removing the water filter housing can be a real pain without the proper technique. My model is a Purwater FHT-34V, the O-ring is part number ORG006, and I use standard 30 micron sediment filters. See the links below for the parts I used:
