How to Install a Foot-Pump Sink in an RV?

Choosing the Right Sink and Components

When selecting a foot-pump sink for your RV, consider the size and capacity of the sink, as well as the compatibility with your RV’s plumbing system. You’ll need to choose a sink that suits the number of occupants and the available space in your RV. A typical foot-pump sink consists of a sink basin, a foot pump, and a check valve. It’s essential to choose a sink with a high-quality foot pump that can deliver sufficient water pressure. For most RVs, a 6-gallon per minute (gpm) foot pump is sufficient.

Installing the Water Supply Lines

To connect the sink to the RV’s water supply, you’ll need to run new water supply lines from the fresh water tank to the sink. This typically involves using 1/2-inch or 5/8-inch PEX tubing, depending on the manufacturer’s recommendations. Use a tubing cutter to cut the PEX tubing to the required length, and then use a tubing crimper to connect the tubing to the sink’s water supply inlet. Make sure to secure the tubing to the RV’s floor or wall using clips or straps to prevent damage and leaks.

Integrating the Drainage System

For proper drainage, you’ll need to connect the sink’s outlet to the gray water tank. Typically, this involves running a drain line from the sink to the gray water tank, using a 1/2-inch or 3/4-inch drain hose. Use a drain trap to prevent sewer gases from entering the RV. Secure the drain line to the RV’s floor or wall using clips or straps, and make sure to slope the drain line slightly to ensure proper drainage.
