Buying a home in Columbia County is a big step, and a plumbing check can make the move-in period much calmer. A general home inspection is helpful, but it may not answer every plumbing question. Before closing, or soon after receiving the keys, look for signs of leaks, ask about the age and service history of major equipment, and make a written list of anything that needs follow-up. Northwest Plumbing Services can help homeowners think through repairs, water and drain lines, repiping, fixtures, and water-heater choices. When a concern involves a sewer line, ask the office what inspection options are currently available for your property.
Start with the water heater
Check the tank or water-heater cabinet for rust, moisture, staining, or a relief-valve discharge pipe that appears damaged. Ask the seller or inspector for the unit’s age, fuel type, maintenance history, and any previous repair records. Older equipment is not automatically unsafe, but its condition and expected remaining life should be part of your budget conversation. For a broader service-planning overview, review our Plumbing Services guidance.
If you are considering a replacement, compare a conventional tank with a tankless model based on household size, hot-water habits, installation requirements, and available space. Northwest Plumbing Services installs both tank and tankless water heaters; call to discuss what fits your home.
Test pressure, fixtures, and drainage
Run cold and hot water at several sinks and showers. Flush each toilet, operate tub and shower controls, and run enough water through sinks to see whether drains clear steadily. A slow drain, weak flow, unusual discoloration, or water that does not stay hot deserves a closer look rather than a quick cosmetic fix.
Look below sinks and around toilets for dampness, swollen cabinetry, mineral buildup, or a musty smell. If the home has a crawl space, basement, or utility area, use a flashlight to inspect visible pipes and connections. Never enter an unsafe or confined area just to inspect plumbing.
- Note which fixture or room shows the symptom and whether it occurs only when several fixtures run.
- Keep photos and inspection notes so a plumber can understand the pattern before recommending work.
Find out what is behind the walls
Ask what materials and approximate ages apply to the supply piping, drain lines, shutoff valves, and visible fittings. Older or mixed materials can affect repair choices and future repiping plans. If you have concerns about lead or another water-quality issue, arrange appropriate water testing through a qualified lab or public-health resource before deciding what work is needed.
For a property with recurring backups, large trees, or an uncertain sewer history, ask whether a camera inspection would be useful. It can help identify roots, breaks, or buildup, but the right next step depends on the property and the inspection findings.
Make a practical plan after inspection
Separate urgent leaks and loss of water service from projects that can be scheduled, such as fixture updates, a remodel, or repiping. Do not open walls or attempt complex repairs based only on a checklist. Share the inspection report, photos, and any seller disclosures with a licensed plumbing professional so the recommendation matches the actual condition of the home.

Questions about this topic
Should I get a plumbing inspection before buying a home?
It can be a useful supplement to a general inspection, especially for an older home, a property with low pressure or recurring backups, or a house with limited plumbing records. Ask the inspector or plumber what areas require closer review.
What should I do if I find a slow drain or leak?
Document the location and when it happens, limit use if water is escaping, and contact a plumbing professional for an evaluation. A slow drain can have a simple fixture cause or point to a larger line concern.
Can Northwest Plumbing Services help with water-heater planning?
Yes. The company’s verified services include tank and tankless water heaters. Call the Oregon office to discuss your current unit, household needs, and available replacement options.
