Serv-A-Pure 818 General Purpose Deionization Tank, 0.44 Cu. Ft.

I use this tank attached to a 1.8 gpm pressure washer to wash my cars. The water here is hard at 450ppm and this little tank works as I had hoped. The only thing I needed to add was a 3/4" NPT male to 3/4" garden hose female adapter and I was all set.
