Question of the day

What is the minimum constant water pressure on the discharge side of the water meter?

Explanation:
The basic idea is to guarantee a usable baseline pressure for the house after the meter. The minimum constant discharge-side pressure is twenty psi because that level provides enough force to push water through the piping and fixtures under normal demand, even with some pressure drop along the service line and through various fittings. If the pressure downstream of the meter were as low as ten or fifteen psi, many fixtures would deliver inadequate flow or struggle to operate properly during simultaneous use. Twenty psi is low enough to be practical for most residential systems, yet high enough to ensure reliable service at the farthest fixtures. A higher minimum, like twenty-five psi, isn’t necessary as a baseline and would impose unnecessary pressure on the system.
