TIPS FOR OUTDOOR PLUMBING
Outdoor Kitchen Plumbing: The Basics
Building an outdoor kitchen is a big undertaking. DIY plumbing is not recommended. Beware that special skills and knowledge are needed to prevent plumbing disasters like leaks, freezing, and burst pipes. Whether you decide to hire a professional or do the work yourself, here are the basic steps:
- Add a water supply line from inside the house, with shutoff valves and drain plugs at the lowest point.
- Run the supply line through the wall of the house and out to the outdoor kitchen.
- Route the pipe through the bottom of the outdoor sink base cabinet.
- Install male-threaded adapters for the sink tubes.
- Install a PVC drainpipe and a sink trap adapter.
- Connect the sink and the trap.
- Dig a hole for a dry well at least 10 feet away.
- Dig a trench out to the dry well, sloping down and away from the house.
- Run a PVC drain line through the trench.
- Install the dry well, connecting the drain line through a hole in the side.
Remember: Your outdoor plumbing is not as well-protected as your indoor plumbing.
