A simple, purpose-built safeguard for your tankless water heater installation. This wall-mount plastic drain pan catches drips and leaks before they damage finished walls, flooring, or cabinetry -- and the included dual-size PVC fitting lets you route any captured water to a safe drain location.
Tankless water heaters are compact and efficient, but every water connection is a potential leak point. Whether it is a loose fitting, a corroded connection, or a pressure-relief discharge, even a small amount of water running down a finished wall or soaking into a floor can mean expensive repairs.
The Camco 11470 drain pan mounts directly behind or below your tankless water heater and provides a collection basin sized to fit units up to 20-1/2 inches wide by 13 inches deep. The low-profile plastic construction is lightweight and easy to cut or trim if needed for tight installations. Once in place, the included PVC drain fitting channels any accumulated water through a hose or tubing to a floor drain, exterior outlet, or catch container.
Sized for units up to 20-1/2" wide x 13" deep -- covers most residential-grade and RV-adjacent tankless models.
Included fitting works with two common drain hose sizes, so you can connect standard tubing without hunting for adapters.
Pre-cut gasket seals the drain fitting to the pan body, preventing seepage around the fitting base.
Mounts behind the heater unit on the wall -- keeps the pan out of sight while protecting the surface behind and below the unit.
Not included: Drain hose or tubing, mounting hardware (screws/anchors for wall surface), or shut-off valve.
Mount the pan flat against the wall surface at the correct height behind your tankless heater. Install the PVC fitting through the pan's drain knockout using the included gasket. Connect flexible drain tubing (not included) to route water to a floor drain, exterior port, or collection vessel. Secure the pan with appropriate fasteners for your wall material.
This pan is designed for tankless (on-demand) water heaters, not standard tank-style RV water heaters. Verify your heater's overall width and depth against the 20-1/2" x 13" pan interior before purchasing. Heaters that are wider or deeper than these dimensions will overhang the pan and reduce leak protection coverage.
