GXWH20S General Electric Water Filter System - Instructions

The old one got streached out of shape. The new one fit fine. Easy!

Replaced filter

I was due to change the water filter cartridge anyway so I ordered the new o-ring and using the wrench supplied with the filter, I did my normal cartridge replacement and changed the o-ring on the housing at the same time. Real easy. I bought spares in case I ever need them. The original o-ring lasted 5 1/2 years.

With this whole house water filter in line with the water heater line, I could see the filter was dirty because of the clear water filter housing and the original filter was white. I used a manufacturer supplied spanner wrench and turned off the water first, then unscrewed the filter housing and replaced with the new white filter cartridge, then re-installed the cartridge housing. The old one was visibly full of dirt because it was nearly black with sediment. I like the original equipment cartridge because it is white, other charcoal filters are black so you can't tell when they are full of dirt.
