Product review (2 stars): ... thought the whole idea of filter and everything was great..
I thought the whole idea of filter and everything was great...but my contractor says that they are bulky...and difficult to change out and even get your hands on another filter.  Also, he didn't like those kind of valves...can readily leak if not careful.  He did it old fashioned way...with welder and permanant valve.  I returned this because of contractor plumber recommendation...actually he spent less putting in another.  But I think it would have done the job...he just didn't like it.rating based upon what he told me.
