What piping is mine and what is M.U.D.'s?
M.U.D. is responsible for the large pipe (water main) in or along the street. Your water service line connects to the water main with a corporation. M.U.D. is responsible for the corporation. You own and are responsible for the water service line from the corporation to your building, plus the plumbing inside your building.
Why is my pressure going to increase?
M.U.D. needs to improve the water system in the northwest Douglas County to meet the water demands of customer-owners. As a result nearly every household or business in northwest Douglas County will experience a pressure increase between 25 and 35 pounds-per-square-inch (psi).
What is a pressure reducing valve (PRV)?
A PRV is a mechanical device that reduces upstream pressure to a lower downstream pressure protecting piping and appliances.
Do I need a PRV?
Local plumbing codes require a PRV be installed on the plumbing system if the water pressure may exceed 80 psi. Your plumber can help determine if a PRV should be installed.
Where should I install a PRV?
A PRV must be installed upstream of the water meter. For one-inch and smaller PRVs, one shutoff valve must be installed upstream of the PRV and one shutoff valve must be installed downstream of the meter.
For PRVs larger than one inch, one shutoff valve must be installed upstream of the PRV, one shutoff valve must be installed between the PRV and the meter, and one shutoff valve must be installed downstream of the meter.
If you have an outside meter pit with a meter larger than one inch, the curb stop may be used as the shutoff valve upstream of the PRV.
Can I adjust my PRV?
Most residential PRVs can be adjusted using the pressure adjusting screw on the top of the PRV. To adjust your pressure:
- Loosen the lock nut.
- To increase pressure, turn the screw clockwise. To decrease pressure, turn the screw counterclockwise.
- Once you are satisfied with your pressure, tighten the locknut. Note: The pressure cannot be increased or decreased beyond the limits of the PRV which usually is listed on the tag attached to the PRV.
If you are not comfortable performing the adjustments, a plumber can help.
Will M.U.D. pay for the installation of a PRV?
No. You own and are responsible for maintaining your water service line and all plumbing inside your building.
What do I do if a leak occurs in my plumbing?
It's important to know where your shutoff valves are located on your plumbing system. Typically, shutoff valves are located under sinks, toilets, inlet and outlet of hot water heaters, and at the water meter.
If a leak occurs in your plumbing, isolate the leak by closing appropriate shutoff valve(s). To shut the water off to the entire system, close the shutoff valve at the water meter. Once the leak has been controlled by closing valves, repairs can be made. Your plumber can help you with plumbing repairs.
What do I do if I suspect a water main break?
If you suspect there may be a water main break, call M.U.D.'s 24-hour Emergency Service, 554.7777. M.U.D. will make necessary repairs.
What area WILL NOT be affected by the improvement?
The area west of Hwy. 31 (204 St.), south of Hwy. 64 (W. Maple Rd.) and north of the W. Papillion Creek will not see a change in water pressure. The exception is Elkhorn Village, a new subdivision at 208th & W. Maple Rd. (see map below).
