I'm new at this so please bear with me. I want to purchase a reverse osmosis water filter for my house. I have my own well and in searching for a filter system, I noticed that some are made for city water, some for well water and some for different ranges of PSI. I need to know how to measure the PSI. Is it the reading on the tank gauge when it turns on and shuts off, or do I need to buy a gauge that I can hookup to an outside faucet?
