FAQs
What are the most common signs of a main water line problem that affects water pressure in McMinnville homes?
Typical red flags include a sudden or gradual drop in pressure at every fixture, unexplained wet spots in the yard, discolored or gritty water coming from taps, hissing sounds near the water meter, and a water bill that is noticeably higher than normal. Because McMinnville’s clay soils can shift with heavy winter rains, small main-line cracks can worsen quickly, so any of these symptoms should be checked by a licensed plumber right away.
What usually causes sudden low water pressure in my McMinnville property’s plumbing?
In our region, the leading causes are (1) leaks or breaks in the main service line between the city meter and the house, often triggered by ground movement or root intrusion; (2) mineral buildup or corrosion in older galvanized steel pipes, which are common in homes built before the 1970s; (3) partially closed or failed shut-off valves; and (4) issues on the municipal side, such as a nearby hydrant use or city maintenance work. A pressure test and visual inspection will pinpoint the exact source.
How can I tell if my low water pressure is coming from my main line or from the City of McMinnville’s supply?
First, locate the pressure-reducing valve (PRV) or main shut-off where your service line enters the house. Attach a pressure gauge to the nearby hose bib and take a reading—normal residential pressure in McMinnville is 50–70 psi. If the gauge is low, shut the house valve off; if pressure rises after the shut-off, the problem is inside the home’s plumbing. If it stays low, the issue is in the service line or the municipal supply. Our technicians can perform a more thorough isolation test and coordinate with McMinnville Water & Light when needed.
Should I repair or replace my main water line if it’s causing pressure issues, and what affects the cost?
Small, localized leaks or root intrusions can often be repaired with spot excavation or trenchless pipe-patch technology. If the pipe is brittle, heavily corroded, or undersized (common with ½-inch galvanized lines), a full replacement is usually more cost-effective and delivers better long-term pressure. Costs depend on pipe material (copper, PEX, HDPE), length of the run, depth, landscaping/driveway restoration, and permit fees. We provide upfront estimates and explain all options so you can make an informed choice.
How quickly should I address a main line leak or pressure drop to avoid property damage?
Immediately. Besides inconvenience, low pressure often means water is escaping underground, which can undermine foundations, create sinkholes, or lead to mold inside crawlspaces. In McMinnville’s wet climate, saturated soil can spread leaks faster than in drier regions. Turning off the house valve and calling a professional plumber the same day can prevent thousands of dollars in repairs.
Do I need a permit for main water line work in McMinnville, and will your plumbing company handle the paperwork?
Yes. McMinnville Building Division requires a plumbing permit for any repair or replacement of the service line from the meter to the structure. If sidewalk or street excavation is necessary, a right-of-way permit from Public Works is also required. Our team secures all permits, schedules inspections, and ensures the job meets Oregon Specialty Plumbing Code, so you don’t have to navigate the red tape.
