I have recently been on a quest to find the water pressure in my house for a reverse osmosis project I have been working on. This has proven quite difficult as the city doesn’t publish their values and pressure would obviously vary throughout the city based on elevation and not only that vary in the house itself depending on the floor and pressure drop.
For the sake of my own curiosity I got a pressure gauge and measured the water pressure in my basement with no usage in the house (no flow). I got a reading of 90psi but I will be investigating this further as I have a suspicion that water pressure changes over the day and year based on water usage in the city.
