RO Pressure Gauge Kit
This sale is for one (1) Reverse Osmosis Pressure Gauge Kit with zero (0) to one hundred (100) PSI reading capability. This gauge has a 2 inch lens, steel case, dry, 1/4 inch NPT, brass tube and socket and it is lower mounted with fittings for inserting the instrument into a RO system. Included in the kit are fittings to attach to the gauge and 1/4" quick connect fittings for easy insertion into the 1/4" tubing on your Reverse Osmosis system. The gauge and fittings are assembled and ready for you to install on your RO system. A Reverse Osmosis Pressure Gauge Kit will take the guess-work out of when to change your filters.
How does it work
1) A pressure gauge kit will tell you the PSI of the water as it enters your Reverse Osmosis membrane housing.
2) Check the PSI on this gauge when your pre-filters are new - be certain to record the PSI number and the date. Then check in 3 months or 6 months and note the change in the PSI.
3) When the PSI reading on your gauge has dropped 6 or 8 points (example - from 60 down to 52 PSI) you need to order new filters. As the PSI drops below 50 PSI, you are beginning to send a greater percentage of water to the drain and less water to the storage tank. When the reading reaches 45 PSI, you will notice a big increase in drain flow.
How do I install the pressure gauge kit
1)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 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) 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.
1)What are the Benefits
1) Pressure drop on the gauge kit identifies when to replace your pre-filters.
2) Properly maintained pre-filters will extend the life of your Reverse Osmosis membrane.
3) Knowing the incoming PSI on your RO system will permit you to better manage the efficiency of your Reverse Osmosis system and thereby reduce the amount of water you will send to the drain and increase the amount of permeate water going to the storage tank.
4) Reverse Osmosis systems with Booster Pumps installed will be able to read the PSI on the gauge to know what pressure setting they have on their Booster Pump switch.
