Laundry Room Plumbing in Oregon City | New Lines, Drains, and Hookups Done Right

Laundry room plumbing in Oregon City covers the supply lines, drain connections, and venting needed to support a washing machine, dryer, and utility sink. This includes running hot and cold supply lines with shutoff valves, installing the drain standpipe and P-trap at the correct height, venting the drain properly, and connecting a utility sink if the layout includes one. We handle laundry room plumbing across Clackamas, Multnomah, and Washington counties as part of our remodel and installation services from our Oregon City plumbing team.

When it is time for laundry room plumbing

If you are finishing a basement or converting a spare room into a laundry space, the room needs supply lines, a drain, and venting that were not there before. If your washer backs up or drains slowly, the standpipe may be the wrong height or the drain line may be undersized or improperly vented. If your laundry hookups are old rubber hoses with no shutoff valves, replacing them with braided steel lines and proper valves reduces the risk of a burst hose flooding the room. If you are relocating the washer and dryer to a different floor or a different part of the house, new plumbing has to be run to the new location.

Many homes in McLoughlin Historic District and Park Place have laundry hookups in basements or garages that were added decades ago with minimal plumbing. Upgrading those connections or moving laundry to a main-floor room is a common project.

Our laundry room plumbing process

We start by evaluating the room layout, the location of existing supply and drain lines, and what needs to be added or moved. For new laundry rooms, we run copper or PEX supply lines from the nearest branch, install individual shutoff valves for hot and cold, and connect a washing machine outlet box. We install the drain standpipe at code-required height with a properly sized P-trap and tie it into the home’s drain-waste-vent system.

If the room includes a utility sink, we rough in its own supply and drain connections. For gas dryers, we run or extend the gas line to the dryer location and test for leaks. We pressure test all supply lines, run water through every drain, and check venting to confirm the system drains properly and does not gurgle or back up.

Laundry room plumbing cost in Oregon City

Adding hookups to an existing room with nearby supply and drain access is the most straightforward job. Finishing a basement laundry or relocating plumbing across the house costs more because new lines have to be run longer distances, sometimes through finished walls or floors. We look at the layout, tell you what is needed, and give you a price before starting work. Call (503) 919-7243 to schedule a walkthrough.
