Water Heater Pans

Water heater pans protect floors, subfloors, and nearby finishes by catching leaks, seepage, and T&P valve discharge from storage tank units. A water heater drain pan adds a low-cost layer of insurance against water damage and often helps satisfy plumbing code in attics, closets, and interior spaces. Most pans include a threaded outlet to route water safely to a floor drain or condensate pump, reducing the risk of hidden moisture and mold.

You’ll find round and square profiles, low‑profile and deep designs, and a range of materials to match your installation. Aluminum and stainless steel pans offer rugged, corrosion‑resistant performance; galvanized steel balances strength and value; high‑quality polymer/plastic pans are lightweight and won’t rust. Common sizes include 20, 24, 26, 30, and 32 inches, with 3/4 in. or 1 in. NPT drain fittings and side knockouts for flexible routing. Look for reinforced rims, rolled edges, and preinstalled fittings to speed setup.

Choosing the right water heater pan is straightforward:
- Measure the tank’s overall diameter (or footprint) and add 1–2 inches of clearance.
- Match the pan depth to the risk area; deeper or high‑capacity pans offer more buffer.
- Select materials for the environment—stainless for coastal or corrosive spaces, polymer for nonreactive installs, aluminum for a light, durable option.
- Verify local code for drain size, termination, and secondary containment needs.

Installation tips:
- Set the pan level, center the water heater, and connect the outlet to a dedicated drain with a consistent slope.
- Use compatible PVC/CPVC/PEX and avoid kinks or uphill runs.
- Add a leak alarm or auto shutoff valve for early detection.
- Keep the drain unobstructed and test the outlet with a small water pour.
