Customer Reviews

4-Stage Reverse Osmosis Water Filtration System - 50 GPD is rated 3.6 out of 5 by 5.
Rated 1 out of 5 by from I have been communicating with 4 Stage RO filter and... I have been communicating with 4 Stage RO filter and installed unit. Two connectors are leaking and the advice I have received "push/pull tubbing to engage 'O' ring in connector". I did that before contacting the supplier. I may have to void any implied warranty and tap and epoxy Brass fittings in place of the leaking tubbing connections. I all requested additional "C" clips, however, I can salvage the "C' from the replaced PUSH IN connectors.

The installation instructions where not complete, missing several steps that I had to guess on. 2.) the operation manual indicates that the until needs to be replaced in 1 year. I did not see this on the sales page anywhere.
