The PSI Meter does not need to be permanently installed in your system. It allows you to determine the water pressure at any point on your Reverse Osmosis System which can make troubleshooting of any potential problems on your system extremely easy. However, if you chose to install the PSI Meter onto your system, there are two main areas where installing the PSI Meter can be of use.
If you are on a well water system, and you think you may have lower then 50 psi throughout your home’s plumbing, a good place to install the PSI Meter is on the feed water line to your Reverse Osmosis System. This will allow for easy monitoring of the source water pressure entering your Reverse Osmosis System. Your system needs consistent pressure at 50 psi or above. Typical well water systems will top out at 60 psi and bottom out at 40 psi. If your water pressure is below, or does drop below, 50 psi we highly recommend an automatic booster pump.
Installing the PSI Meter on the section of white tubing coming out of the third pre-filter housing will allow you to monitor the psi of the OUTPUT water of the 3 pre-filters. When you install new pre-filters make a note of the psi reading at this point. Write down the psi measurement with some permanent marker on a piece of masking tape and stick it somewhere visible on the system. Now you can check to see when the psi on this line drops to 15% below the initial reading you wrote down (0.85 x initial psi reading). When this happens it is time to replace your pre-fllters. You might want to also write down on the masking tape the number you are watching for, 0.85 x initial psi reading, to make it easier to determine the status of your system.
You really need both a PSI and a TDS meter. This PSI Meter is critical for system maintenance and problem solving. If you have a problem, the second thing Aquasafe will ask is "what are the PSI readings?". We strongly recommend buying PSI and TDS meters as they are absolutely essential in diagnosing problems, and confirming the system is operating as it was designed.
