Houses built around 1986 have copper plumbing that is 40 years old this year. In College Hill and across town, that's the age when we consistently see pinhole leaks start to appear from decades of internal corrosion and water movement. The pipe walls thin out over time, and you'll often notice small, persistent damp spots on walls or ceilings before a full breach happens.

Yes, the Pullman Building Division requires a permit for water heater replacement, and the work must be done by a plumber licensed with the Washington State Department of Labor & Industries. I pull the permit, schedule the inspection, and handle that red tape so you don't have to navigate the codes and paperwork yourself.

Water from the Grand Ronde Aquifer is rich in minerals, leading to hard water scale. This chalky buildup coats the inside of pipes and, critically, accumulates on water heater elements and inside faucet cartridges. It reduces efficiency, causes premature heater failure, and leads to low flow at fixtures unless addressed with softening or regular descaling.

Municipal water pressure here is generally good, but pressure regulators on homes from the 80s often fail after 40 years. A failing regulator can let in surges of high pressure, which stresses old copper joints and appliance connections. You might hear water hammer or see leaks at toilet supply lines or the water heater connection.

Heading past Martin Stadium on US-195 gets us onto College Hill efficiently. From central Pullman, it's typically a 20 to 30 minute dispatch route. We plan routes to avoid game day traffic around the stadium to ensure reliable response times for leaks or no-heat calls.

For 40-year-old copper systems, joint failures are frequent. The soldered joints can corrode, and scale buildup from our hard water restricts flow, stressing the pipes. We often replace entire sections of horizontal runs where pinhole leaks cluster, rather than just patching single spots, to prevent recurring issues.

Yes, the slope on College Hill and near Martin Stadium stresses the main sewer line. Gravity pulls waste downhill, but the constant tension on pipe joints can cause them to separate or sag over time. This creates low spots where debris collects, leading to frequent drain backups that require more than just a simple clearing.

Before the spring thaw hits its peak, disconnect your garden hoses and shut off the exterior hose bibs from inside the house. A hose left connected traps water in the bib; when overnight temps still dip near 24 degrees, that water freezes, expands, and can split the pipe inside your wall, leading to a major leak when it thaws.
