Water Pressure Gauge Meter 0-1.6MPa 0-220psi 1/4″ f Reverse Osmosis System Pump  and suitable for all RO systems to monitor pressure and optimum performance of membrane.

It is the pressure of water that forces the water through the membrane for purification and flushes the rejected solids away. Low water pressure will result in reduced production and premature fouling of the membrane. The ideal pressure for operating an R.O. system is 60 PSI. Pressure below 40 PSI is generally considered insufficient, and should be boosted using a pressure booster pump.  Along with water temperature, pressure is a critically important parameter in determining how well your system operates. The purpose of the pressure gauge you’ve purchased is to display the pressure present in the system that will affect the performance of the RO membrane. Factory specifications for Filmtec membranes call for 50 psi; specifications for residential membranes produced by other manufacturers are commonly higher (e.g., 60 or 65 psi). Begin the installation by selecting a location for the gauge. The gauge can be mounted by drilling a hole through your RO system bracket, or the gauge can be positioned to rest atop the RO membrane housing. Do not allow the gauge to hang loosely from the system supported only by the tubing and fittings in the kit.

Note the pressure shown on the gauge when new prefilters are installed. If the pressure is too low (e.g., below approximately 40 psi if you have a Filmtec membrane), you will be unhappy with the performance of your system. Assuming your pressure approximates manufacturer’s specifications, recheck the gauge periodically. Loss of pressure reaching the membrane indicates one or more of the prefilters is clogged and needs to be replaced. To determine which prefilter is not allowing the free passage of water, remove the sediment filter (only) and note any changes in system pressure. If the pressure returns to that experienced when the prefilters were new, the sediment filter is clogged. If the pressure does not improve, the carbon block (and perhaps the sediment filter as well) is clogged. During this troubleshooting, do not operate your system without the carbon block in place for longer than a minute. Operating the system without a prefilter carbon stage will expose the membrane to chlorine and may damage the membrane.

What are the Benefits of using a Pressure Gauge Kit

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 pressureI on the gauge to know what pressure setting they have on their Booster Pump switch.
