Owner-operated drain & sewer service in Ballard, Seattle

Sewer Cleanout Service in Seattle

The cleanout is the front door to your sewer line. We find it, open it safely, clear the line from it and camera through it, and if your house does not have one, we use the next best access and tell you which before we price it.

The short answer

A sewer cleanout is a capped access fitting on the pipe that carries wastewater from your house to the city sewer. It lets a drain technician clear and camera the whole line from outside without pulling a toilet. We clear lines through the cleanout for $200–$600 flat, or $500–$700 jetted.

What sewer cleanout service covers, and what it costs

Most calls start with the same question: where is it, and is it safe to open? We answer both before any cable goes in.

We locate the cleanout, open it the safe way, clear the line toward the city main with a cable or the jetter, then run water and camera it so you see what caused the blockage and where.

No cleanout, buried cleanout or a cap that will not budge? We clear through a pulled toilet or another access and say which one before we price it. That is the same approach as our main sewer line cleaning.

Where to look for your cleanout

Four places cover most Seattle houses. Start with the first one and work down.

BasementOutside wallNear the lineMainSide sewer, owned to the main1234
Drain line Where it fails
  1. 1

    Outside, near the foundation

    Usually on the street side, as a capped pipe a few inches above grade or a cover in a bed or walkway. Seattle’s side sewer rule calls for one adjacent to the building foundation.

  2. 2

    In the basement

    A threaded cap low on the main drain, or a plug in the floor near where the pipe leaves the house.

  3. 3

    Out along the line

    On longer runs, a second cleanout or a test tee closer to the property line or sidewalk.

  4. 4

    No cleanout at all

    Common in older houses. A toilet comes off its flange and becomes the access point.

Seattle’s side sewer cards often show the pipe route and fittings. Look your address up in the side sewer card viewer.

How to find your sewer cleanout in five minutes

Most Seattle cleanouts are found with a walk around the house and one look at the City’s records.

  1. Find the street side of the house

    The side sewer runs from the house toward the sewer main under the street, so the cleanout is almost always on that side.

  2. Walk the foundation line

    Look for a capped pipe a few inches above the soil, or a small round or square cover in a bed, lawn or walkway within a few feet of the wall.

  3. Check below the lowest bathroom

    In a basement or crawlspace, follow the largest drain pipe toward the outside wall. A threaded cap or a plug in the floor near that wall is the indoor cleanout.

  4. Pull your side sewer card

    Look up the address in the City’s side sewer card viewer. Where a card exists, it often sketches the pipe route from the house to the main.

  5. Leave the cap on

    If the line is backed up, a loosened cap can let sewage out under pressure. Once you know where it is, call and we take it from there.

What a cleanout cover looks like

Cast covers stamped CLEANOUT, square boxes in a walkway, or a plain capped pipe. Grass and mulch hide most of them.

Leave it closedIf you are not sure a cover is your sewer cleanout, leave it closed and call. A cap on a full line can let go under pressure.

What Seattle’s rules say about cleanouts

The City sets where cleanouts go on new side sewers. It does not require you to add one to an old line.

Permit to replace one

$280 sanitary repair permit, per SPU

  1. One beside the foundation

    Seattle’s side sewer design rule calls for a cleanout adjacent to the building foundation on the upstream reach of the last wye in the side sewer.

    Seattle Director’s Rule 4-2011
  2. One every turn or 100 feet

    The same rule calls for a cleanout for each total change of 90 degrees in grade or alignment, or every 100 feet of pipe.

    Seattle Director’s Rule 4-2011
  3. Two-way cleanouts count

    The Seattle Plumbing Code allows an approved two-way cleanout near where the building drain meets the building sewer, or outside at the low end of the building drain and extended to grade.

    2021 Seattle Plumbing Code, 707
  4. Replacing one takes a permit

    SPU requires a side sewer repair permit any time a pipe or an external fixture such as a cleanout needs repair or replacement; a sanitary repair permit generally costs $280.

A cleanout is the one part of a sewer line a homeowner can actually see. Know where yours is before the night you need it, and the whole job gets simpler, cleaner and cheaper.

Through a cleanout or through a toilet?

Both work. The cleanout is faster, cleaner and reaches more of the line.

Through the cleanout, on camera

The cleanout is where the camera goes in. This is what it shows, and what we do when there is no cleanout to use.

Distance on every defect

The camera counts footage from the cleanout, so roots, offsets and bellies are located, not guessed.

Footage is yours

You get the recording to keep, or to send to a repair contractor or an inspector.

No cleanout, still a camera

From a pulled toilet or a fixture, we can still run the camera and show you the line.

Still have a question?

Shane answers the phone himself, 8 AM to 8 PM, seven days a week.

What is a sewer cleanout?

A capped access fitting on the pipe that carries everything out of the house. Seattle’s side sewer rule describes it as a wye fitting in the side sewer, brought up to an access point so the line can be cleaned and inspected without pulling a toilet.

Where is the sewer cleanout on a Seattle house?

Most often outside, close to the foundation on the side facing the street, as a capped pipe or a small round or square cover in the lawn, a planting bed or a walkway. In houses with basements it is often a capped fitting low on the main drain or in the floor. Older houses sometimes have none.

What if my house has no cleanout?

We can usually still clear and camera the line through a pulled toilet or another fixture. We tell you which access we would use before we price the job, and whether a cleanout would make future cleanings easier.

Do you install sewer cleanouts?

No. Seattle Public Utilities requires a side sewer permit to repair or replace an external fixture such as a cleanout, and that work goes to a side sewer contractor. We can show on camera where one would help.

How much does it cost to clear a sewer line through the cleanout?

Ours is $200–$600 flat to clear the line, or $500–$700 when it needs hydro jetting. A camera inspection on its own is $300–$400. There is no trip fee.

Should I open the cleanout myself during a backup?

Be careful. If the line is full, sewage can come out under pressure when the cap loosens. Seattle Public Utilities also advises calling Puget Sound Energy at 1-888-225-5773 before clearing a side sewer blockage, to avoid damaging a gas line.

How can I find my cleanout on City records?

Seattle keeps side sewer cards, the City’s records of how many properties’ side sewers were installed. Look up your address in the City’s side sewer card viewer; where a card exists, it often sketches the pipe route.
