i've really had it with the hard water in bergen county.  my six year old boiler/furnace heat exchanger core  just broke and i truly believe its the hard water.  my finished basement has like ZERO room in the mechanicals area.  a year ago i asked a plumber about the new GE unit its quite compact and he said he wouldnt install it "i'm not familair with it and if it fails later you will blame me."  (okay i kinda get that).  the garage is on entire other side of house of city water supply.  i think the GE unit can get in a corner but i'd need to be able to "slide it over" if my electric panel needed a major service.  So basically i need to find a plumber/installer who will really sort of customize how/where i want to install it.  and also the sump drain is right there to..  thats another thing you have to think about discharge.  i'm a pretty handy guy but i need to plumb out: split off city water with a bypass, then plumb around the irrigation/lawn supply, then plumb over to the GE unit but make it easily accessible if i had to do the aforementioned "slide over".    But all i know about "compact" systems is what i know from googling around.. maybe a dedicated company can suggest a split system or something..  i dunno..

Not sure if they go out to Bergen county, but water is their business.  Did my softener and reverse osmosis system.

apparently all i had to do was Google around.. ill make some calls.   thank you for the referral, that company has some pretty good reviews.

For what it's worth, I'm decently happy with US Water Systems. Granted, they just supply the machines. But it's easy enough to connect yourself and doesn't require too much plumbing skill.
