View Full Version : GE Whole House Water Filter

I have a GE Whole House Water Filter - GNWH38F. It has worked great as a filter, but it has been very difficult to change the filter (release the pressure to take out the old filter). I had it installed by my plumber, which cost me multiples of the cost of the unit - but I was pleased to have filtered water and installing it was definitely beyond my skills. My plumber put a ball valve on each side of the unit.

I got the newer model, GXWH40L, which has the same dimensions, takes the same filter... and I imagine because the biggest difference is certain ways to change the water coming into it, that changing the filter will be easier.

So my question is... is swapping one unit for the other something I (with my limited plumbing skills) can attempt - or should I call in the pro? I don't need to sweat pipe this time around or do any soldering... it is held in with a compression fitting.

If I need or you think I should call in the pro to change this, I will... but thought I'd see if this falls into the "really easy" category first (primarily because the hard work has been done in that there is already a filter unit there now and I'm replacing one with the other).

Appreciate the advice, as always.

Depends on your skill level...probably easy. Post a picture, and the pros can give you a better idea of any possible pitfalls. The biggest issue is the actual gap, after the old one is out. If it is different, you may be putting tension on the lines, and there may not be any give. It depends on how they are routed, and anchored.

Dimensions are exactly the same. There are pictures on this page of the GE website, which looks like my filter... but I looked up the specs and the width of the units is exactly the same.
