Had a little problem with this unit. Don't know if it is the unit or the housing it fits into, but I cannot get it to stop leaking. I tried several times to re-seat the gasket (o-ring) to no avail. No matter what I did, the best I could do was to slow the leak to a fast drip. I can use this filter until it's life is out, but if the next one does the same thing I am not going to be happy. The ratings on the filter itself are some of the best on the web, but it you can't stop the leak it does no good. I finally got it acceptable with the old trick of rolling a length of Teflon tape into a rope and stuffing that into the slot along side the o-ring to fill the gap. That slowed things down to a drip when the filter is activated which is annoying but tolerable.
The only thing I am not sure about is if the FM-15 and the FM-25 are meant to fit the same housing. I had an FM-25 installed before this that did not leak. I didn't see anything in the paperwork about a difference, except that the FM-25 is chrome, but that would not be the first time something like that was omitted.
