Pressure gauge for RO system

[Stu]

I use the hose attachment for my RO system, and I want to be able to monitor the ingoing water pressure so I can keep the system operating efficiently. I'm going to get a pressure gauge, and I'm wondering which line it goes on. Does it go on the incoming line, or does it go on one of the outflow lines from one of the filters?

 

Also, where can I get one of these locally? I'd like to pick one up.

From a Spectrapure manual:

"The pressure gauge is used to monitor the condition of the Sediment and

Carbon Pre-Filters (not the RO Membrane). When the filters are new,

the gauge will indicate the actual available water pressure. As the filters

collect particulates, the pressure will begin to drop. A 15-20% drop in

pressure would indicate that the pre-filters are in need of replacement."

 

This means, put the gauge between the sediment/carbon prefilters and the RO membrane. I have picked one up at Lowes before also.
