Outdoor Kitchen Plumbing Diagram
An outdoor kitchen with a working sink means the cook can rinse produce and wash up without running in and out of the house all night. ArcSite's outdoor kitchen plumbing diagram follows the drain from the sink's P-trap underground to a sewer cleanout at the house.
Key Features
This outdoor kitchen plumbing diagram includes:
- Outdoor sink and faucet set in the cabinet
- P-trap under the sink
- Drain riser down through the cabinet base
- Sloped underground drain line
- Wye fitting at the house sewer line
- Sewer cleanout at grade
- House wall and foundation in section
The drain line slopes back toward the house the whole way, so set your grade before you trench and don't leave a low spot that holds water and freezes.

Why an Outdoor Kitchen Plumbing Diagram Matters
Frequently asked questions
Does this diagram include the water supply?
No. It shows the drain side only: sink, P-trap, drain line, and the sewer tie-in. Add the hot and cold supply lines and a vent in ArcSite to finish the plan.
Can I move the sink farther from the house?
Absolutely. Stretch the drain line in ArcSite and keep the slope running back to the cleanout.
Do my guys need CAD training for this?
No. If you can sketch a drain run on a napkin, you can draw it in ArcSite, with no CAD learning curve to get through first.
