"Adam was safe, courteous and fixed an undersink blockage for us. He worked quickly and cleaned up after himself, explaining everything he was doing and why. He also cleaned 2 outside gutter drains and diagnosed 2 others that had breakages or collapses. We would recommend him highly. We live in Beaverton, OR."

"Tyler and Armondo are true professionals in their workmanship and customer service. They took on the challenge to install our new shower overcoming all challenges to construction and plumbing. Kept us informed of the progress (even though the company overbooked work). The long wait for install was well worth the end results. Best of all I didn't have to do it myself, and the warrenty is parfect."

"5 stars ​A friend in Lake Oswego recommended Three Dogs Plumbing, and they did not disappoint. They swapped out two indoor faucets and installed a new water heater quickly and cleanly. The plumber worked fast, left no mess behind, and made sure everything ran perfectly before leaving. Highly recommend them for any home plumbing needs!"

"Agustin and his team have completed several projects for us, including framing a 1,000 sq ft deck, a light kitchen remodel, plumbing work throughout the house, and bathroom touch-ups. Every project has been completed on time, at a very reasonable price, and with great attention to detail. Agustin is professional, respectful, and genuinely great to work with. He takes the time to understand what we’re trying to accomplish and always communicates clearly throughout the process. One thing we especially appreciate is his willingness to collaborate—if our original idea doesn’t quite fit the budget, he’s proactive about suggesting creative solutions that still achieve the look and functionality we want. It’s been a great experience working with him, and the quality of his team’s work really shows. We will absolutely be hiring Agustin again and highly recommend him to anyone looking for reliable, high-quality work."

Plumbing FAQs, answered by experts

Upgrading your home's system offers immediate and lasting benefits. In the short term, completing plumbing improvements reduces water bills and prevents emergency repairs during the heavy Rainier wet season. Long-term benefits include avoiding extensive moisture damage and ensuring compliance with OR building codes. Documented improvements also add verifiable resale value, which is essential for older homes with aging galvanized steel pipes in the area.

Helpful?

Identifying your pipe material is a critical first step, as pre-1970 homes in Rainier have aging galvanized steel lines. Check your crawl space for moisture levels and inspect the condition of existing pipe insulation. You must also verify whether your home connects to the city sewer or a septic system. Finally, review past permit records to ensure all previous plumbing work meets OR state code requirements.

Helpful?

Start by locating and testing your main water shutoff valve, which sits in the crawl space of older Rainier homes. You can safely clear slow sink drains using a drain snake, but avoid chemical cleaners that damage older pipes. Wrap exposed pipes before a winter freeze to prevent bursts. Always hire a licensed professional for any plumbing tasks involving the city water meter or sewer connections.

Helpful?

Homes built before 1960 are prime candidates for updates due to aging galvanized steel pipes. Look for visible water stains, mineral deposits around fixtures, or unexplained moisture in your crawl space. Low water pressure and discolored water are strong indicators of interior pipe corrosion. If your home lacks a permit history for past plumbing work, schedule an inspection with a local professional to protect your property value in Rainier.

Helpful?

Create a reliable routine by inspecting your crawl space for moisture and flushing your water heater every fall. During winter, monitor the weather for hard freezes and verify your sump pump operates correctly. Spring is the ideal time to check exterior hose bibs for freeze damage. Schedule any major plumbing upgrades during the dry Rainier summer months, as OR crawl spaces are much easier to access then.
