Sewer Cleanout Installation in Denver

Sewer Experts installs new sewer cleanouts, replaces broken caps and risers, raises buried cleanouts to grade and adds two-way cleanouts on lines that need access in both directions. Most jobs are done in a day, across the Denver metro.

What a sewer cleanout isA capped pipe that rises from your sewer line to the surface, usually near the foundation or in the yard. It gives a plumber a direct way into the line for a camera, a cable or a jetter, and it is the first place a backup shows itself, outside, instead of in your basement.

Why it matters: without a cleanout, every camera inspection, cleaning and jetting has to go through a roof vent or a pulled toilet.
Why homes need one

Life without a sewer cleanout

Many older Denver homes were built without an exterior cleanout, or the one they had was buried under a patio, a garden bed or thirty years of topsoil. Here is what that costs you.

Without a cleanout

Every service call is harder and dearer

  • A camera inspection means pulling a toilet or climbing on the roof to go in through a vent. Extra time, extra cost, and a toilet to reset.
  • Cabling and jetting run from inside the house, so the mess is inside the house.
  • When the main line blocks, sewage backs up at the lowest fixture, usually a basement floor drain or shower.
  • Locating and repairing the line takes longer because there is no fixed access point to measure from.
  • Some plumbers will not run a full-size cutter or jetter without one, so you get a smaller, less effective clean.
With a cleanout

Ten minutes to open, and the mess stays outside

  • Camera, cable and jetter go straight into the line from the yard. Inspections and cleanings cost less every time.
  • A blocked main backs up at the cleanout first. Pop the cap and the sewage comes out in the yard, not the basement.
  • A two-way cleanout lets the line be cleaned toward the house and toward the street from one spot.
  • Home inspectors and buyers look for one. It is a small selling point on an older house.
  • It is required by code when a sewer line is replaced, and the inspector will look for it.

New PVC wye and cleanout riser cut into a sewer line in a small excavation

New cleanout installation

We locate the line, dig a small pit, cut in a wye fitting, and bring a riser up to grade with a threaded cap. Backfilled, compacted and restored the same day.

Two cleanout risers side by side in a trench for a two-way cleanout

Two-way cleanouts

Two risers on a double wye, one facing the house and one facing the street, so a cable or jetter can work the whole line from one access point. Standard on our sewer line replacements.

Two green sewer cleanout caps set flush at grade after backfill

Raising buried cleanouts

A cleanout under sod, mulch or a paver patio is no use in an emergency. We find it, extend the riser and set a new cap flush with the finished surface.

Cap and riser replacement

Cracked caps, rusted cast iron plugs, and risers crushed by a mower or a vehicle. Replaced with the right fitting for the pipe, threaded so it can be opened again.

Cleanouts on repairs and replacements

Every sewer line repair or replacement we do gets a code-compliant cleanout as part of the job, placed where it is easiest to reach and inspected with the line.

Commercial and multi-unit

Access points on shared laterals, restaurant grease lines and long commercial runs, sized for the pipe and spaced so maintenance crews can reach every section.

How it goes

A cleanout install is a small dig, not a big one

1 dayTypical cleanout installOne pit about the size of a card table, a few feet deep. Yard, driveway or sidewalk put back the same day.
1

Locate the line

We locate the sewer line and pick the spot: close to the house, clear of the foundation, easy to reach.

2

Dig a small pit

Colorado 811 locate first, then a mini excavator or hand tools open a pit down to the pipe. Sod is cut and saved.

3

Cut in the wye and riser

A section of pipe comes out, a wye or double wye goes in with proper couplings, and the riser is brought up to grade with a cap.

4

Backfill and restore

Backfilled in compacted lifts, cap set flush, sod or surface replaced. If a permit was required, the inspection happens before we close it.

Denver code and inspections

When a cleanout is required

Plumbing code requires cleanouts at set points along a sewer line, including where the building drain meets the sewer lateral, so that every section can be reached for cleaning. When a sewer line is repaired or replaced in Denver, a compliant exterior cleanout is part of the permitted work and the inspector checks for it before the trench is closed.

If your house never had one, nobody will force you to add it. But the first time the line backs up, you will wish you had. We pull the permit when one is needed and build the cleanout to the inspector’s spec. Questions about who owns what along the line are answered in our guide to sewer line responsibility in Denver.

Cleanout terms, plainly

Riser
The vertical pipe from the sewer line up to the surface.
Wye
The Y-shaped fitting cut into the line that the riser connects to, angled so tools can enter in the direction of flow.
Two-way cleanout
Two risers on a double wye, giving access toward the house and toward the street.
Cap or plug
The threaded cover at grade. Plastic on modern lines, brass or cast iron on older ones.
Test tee
A straight-through fitting used near the house where the line changes direction, easier to reach than a wye.
Sewer cleanout installation cost

What sets the price

A cleanout on its own is one of the smaller jobs we do. It is priced by the site, not by the hour, and quoted after we know where the line runs.

Included in a standard install

  • Locating the line and marking the spot
  • Colorado 811 locate request
  • Excavation, wye or double wye, riser and threaded cap
  • Backfill in compacted lifts and surface restoration
  • Permit and inspection when required
  • A camera look at the line while it is open

What adds to it

  • Depth: a line six feet down is a bigger pit than one at three feet
  • Concrete or asphalt on top instead of lawn
  • A two-way cleanout instead of a single
  • Cast iron or clay pipe that needs special couplings
  • Tight access between houses that rules out a machine
  • Combining the cleanout with a spot repair or line replacement, which is usually the better value
Questions

Sewer cleanout questions from Denver homeowners

How do I find my sewer cleanout?

Look for a capped pipe, three to four inches across, sticking a few inches out of the ground near the foundation on the street side of the house, or in the basement floor near where the main line leaves. Older homes may have one buried under sod or a patio. If you cannot find one, we can locate the line and tell you whether one exists.

How much does it cost to install a sewer cleanout in Denver?

It depends on the depth of the line, what is on the surface, and whether you want a single or two-way cleanout. It is a one-day job in most yards. Call with your address and we will quote it, and if you are already having the line repaired, adding the cleanout at the same time costs much less.

Do I need a sewer cleanout?

Nobody will require you to add one to an existing line. But you need one the day the line backs up, when a plumber has to get a camera or a cable into it. It is the difference between a quick service call and pulling a toilet or going in through the roof.

What is a two-way cleanout and do I need one?

A two-way cleanout has two risers on a double wye, so a cable or jetter can be sent toward the house or toward the street from one spot. It is worth it on longer lines and on any line that gets cleaned regularly for roots. It is standard on our sewer line replacements.

Why is my sewer cleanout overflowing?

The main line is blocked downstream of the cleanout and the cleanout is doing its job: letting the backup out in the yard instead of in the basement. Stop running water in the house and call us. The cleanout is also where we will clear the line from.

My cleanout is buried. Can it be raised?

Yes. We locate it, dig down to the riser, extend it with the right pipe and set a new cap flush with the surface. If the old riser is broken or the fitting is the wrong type, we replace it while it is open.

Is a cleanout required by code when replacing a sewer line?

Yes. A sewer line replacement in Denver is permitted and inspected work, and a compliant cleanout is part of it. Every replacement we do includes one, usually a two-way, placed where it is easiest to reach.

Can a cleanout go inside the house?

Many homes have one in the basement where the main line leaves the building. It works for access but not as a relief point, because a backup comes out on the basement floor. An exterior cleanout does both jobs, which is why we recommend it.
