What a cleanout is
A cleanout is a capped pipe fitting that opens directly into the drain line, put there so the line can be cleared or inspected without removing a toilet or cutting into a wall. The main one sits on the building drain or lateral, usually just outside the house. Some homes also have smaller cleanouts on branch lines inside, often under sinks or in walls.
On older Stanton homes the main cleanout is frequently near the front of the house, along the side yard close to where the line exits the slab, or in a small ground-level box. Landscaping, pavers and decades of mulch can hide it.
Where to look
- Along the foundation on the side facing the street
- Near the bathroom side of the house, where the main line often leaves
- In planter beds and under shrubs close to the wall
- In a small round or square box set in the ground near the front walk
- In the garage or a service area on some homes
- Near the property line on homes where a two-way cleanout was added
Recognizing it
| What you find | What it likely is |
|---|---|
| Round cap, 3 or 4 inches, with a square nub or recessed socket | Drain cleanout |
| Tall pipe with an open top above the roof line | Vent, not a cleanout |
| Box with a meter or valve inside | Water meter or shutoff, not a cleanout |
| Pipe ending in a flat cap at ground level near the street | Possibly a property-line cleanout |
If you cannot find one
- IfYou find no cleanout anywhere outsideAsk a plumber to check indoor cleanouts or locate the line; some older homes simply lack one.
- IfThe cleanout is buried under concrete or deckingAsk whether it can be raised or relocated for access.
- IfThe cap is seized or brokenA plumber can remove and replace it with the right tool.
- IfThere is no usable cleanout at allAsk about adding one, and check with the city on any permit needed.
Worth knowing
- Why it matters
- Clearing from a cleanout avoids pulling a toilet and reaches the lateral directly.
- Keep it clear
- Leave room around the cap so a machine can be set up next to it.
- Mark it
- Note its location somewhere the household can find it.
Common questions
Is the cleanout the same as the water shutoff?
No. The cleanout opens into the drain line. The water shutoff controls the incoming water supply. Both are worth locating in advance.
Can I open the cleanout to check the line?
Only if you are sure the line is not backed up, and with care. If in doubt, leave it closed.
Should I add a cleanout?
If your home has none and you have had main-line problems, adding one is a common improvement. Ask a licensed plumber and check permit requirements with the city.
