Shoreline Plumber

Lighthouse Plumbing works across Shoreline — North City, Ridgecrest, Briarcrest, Echo Lake, Richmond Beach and Innis Arden. Most of what we're called for here sits behind mid-century kitchens and bathrooms: drains that were sized for a different era, and fixtures that have outlived the pipe feeding them. We come over from Fall City, so we schedule Shoreline properly rather than pretending it's around the corner.

Why Shoreline Homeowners Call Us

We'd rather diagnose than guess

We'd rather diagnose than guess

A camera in the line costs a few minutes and settles the argument. We use one before recommending anything that involves opening a wall.

We fix the cause, not the symptom

We fix the cause, not the symptom

A kitchen sink that backs up every few months usually isn't a cabling problem. It's a branch drain that's undersized, poorly graded, or both. We'd rather open the wall once and rebuild it correctly than come back three times with a machine.

We bring the work up to current code

We bring the work up to current code

Plenty of Shoreline kitchens were plumbed to what was acceptable at the time and never touched since. When we replace a section, it goes back in to today's Uniform Plumbing Code — correct diameter, correct grade, correct fittings, properly supported.

We know the housing stock

We know the housing stock

Shoreline reads as one city and plumbs as three. The 1940s and 50s cottages through Ridgecrest and Briarcrest, the larger postwar homes in Innis Arden and Richmond Beach, and the newer infill along the Aurora corridor were each built to different standards. What's behind the cabinet depends a lot on which one you own.

We work clean in tight spaces

Half of Shoreline's older housing sits over a crawlspace, and that's where the branch drains run. It's not glamorous work. It's also where the actual problem usually is.

Recent Work in Shoreline

In July we rebuilt the kitchen drainage in a Shoreline home where the sink had never drained properly. Caleb opened the back of the cabinet, dropped the existing drain stub-out to a workable height, then replaced the whole kitchen branch drain from the sink connection back to the main trunk line. The new run went in as 2-inch ABS at proper grade, which is what current code calls for on a kitchen waste line — the old one was undersized for what a modern sink and dishwasher put through it.

The homeowner had been living with a slow sink since they bought the place, assuming it just needed cabling more often. It didn't.

He also fitted a new dishwasher air gap and reconnected the dishwasher drain to the new line. The whole system got flow-tested and checked for leaks before we handed the kitchen back.

Shoreline Plumbing Questions

Why does my Shoreline kitchen sink keep backing up after it's been cabled?

Because cabling clears the blockage, not the reason it formed. If the branch drain is undersized or running flat, waste will keep hanging up in the same spot. A camera down the line tells you which one you're dealing with in about ten minutes.

What size does a kitchen drain actually need to be?

Two inches, under current Uniform Plumbing Code, for a kitchen waste line. A fair number of older Shoreline kitchens were built with less than that, which was acceptable then and isn't now. It matters more today because dishwashers and disposals push far more through the line.

Who is my water and sewer provider in Shoreline?

That depends which side of the city you're on. North City Water District covers the east side and part of Lake Forest Park; the west side is served by Seattle Public Utilities. Sewer for almost the whole city runs through the old Ronald Wastewater system, now under the City of Shoreline.

Do you have to cut into my cabinet or wall to do this?

Sometimes, and we'll tell you before we start. Reaching a branch drain usually means opening the back of the sink cabinet, and occasionally a small section of wall. We keep the opening as small as the work allows and leave the site clean.

How quickly can you get to Shoreline?

We're based in Fall City, so a Shoreline job is a planned trip rather than a same-hour response. We'll give you a genuine arrival window when you book, and we keep it. For the kind of work most people call us for here — a drain that's been failing for months — that's rarely the deciding factor.

Serving Shoreline from Fall City

Shoreline is a genuine cross-county drive from our shop, far enough that we plan around it rather than squeeze it in. We're a Snoqualmie Valley company working the north end deliberately, not accidentally. Shoreline sits at the far side of our range, and we're upfront that a local shop will always beat us on an emergency. Where we earn the drive is on the jobs that need doing once, properly — the drain that's been cabled four times, the remodel that has to pass inspection.
