Question: How do I install a pressure gauge kit on my Reverse Osmosis system?




Most Reverse Osmosis owners are concerned about when to replace the filters on their RO system. A Pressure Gauge Kit will provide them with a heads-up as to when the filters are nearing depletion.

How do I Install this Pressure Gauge Kit

Installation of a RO Pressure Gauge Kit is not difficult and will only take about one minute.

1) If your RO system is on city water or well water (without a Booster Pump), locate the 1/4″ tubing (usually it is RED) between the final pre-filter and where the tubing enters the ASO valve.

2) Cut the tubing (take care to cut it square – not at an angle).

3) Insert one end of the tubing into the male connector on the pressure gauge kit and the other end of the cut tubing is to be inserted into the male connector on the opposite side of the gauge kit. HEY – you’re already done.

4) On Reverse Osmosis systems with Booster Pumps installed, locate the Pressure Gauge Kit between the outlet port on the Booster Pump and the inlet on the ASO valve.

5) Should you have a Reverse Osmosis system with a Booster Pump already installed,  you would locate the pressure gauge kit between the outlet port on the Booster Pump and the inlet fitting on the ASO valve.

6) In # 2 above we noted how to check the PSI on your system when the pre-filters are new and then again 3 months later. With a Booster Pump installed, when you test the PSI after the pre-filters, it is best (more accurate) to unplug the Booster Pump and measure the PSI based on the water pressure without the Booster Pump. The efficiency of the Booster Pump will overcome some of the loss of PSI caused by pre-filter depletion and therefore you will not get an accurate signal as to when you should change the pre-filters.
