Montgomery County Environmental Services' water mains have a pressure ranging from 32 psi to 145 psi, depending on your location in our distribution system. Factors influencing this range may include, but are not limited to:
- the pressure zone that services your property;
- the air temperature;
- the type of material, size, and condition of your water service line (the pipe from the water main to your property);
- whether or not there are any leaks at your property or in our water mains.
When the static pressure in your property is greater than or equal to 80 psi, Section 4101:3-604.8 of the Ohio Plumbing Code states "an approved water-pressure reducing valve conforming to ASSE 1003 with strainer shall be installed to reduce the pressure in the building water distribution piping to 80 psi (552 kPa) static or less." Over time, excessive pressure may damage plumbing fixtures in your property, cause noisy pipes, and possibly lead to leaking pipes. The installation of this valve is at the customer's expense.
Note that in areas of Montgomery County that experience low water pressure, Section 3.11 of our Rules and Regulations states "the Sanitary Engineering (now Environmental Services) Department does not guarantee a fixed pressure…" If the pressure is inadequate to provide enough flow to plumbing fixtures in your property, then a booster pump and pressure tank may be installed at the customer's expense.
