Frequently Asked Questions

Do I need a water heater pan?

Water heater pan requirements vary by location, but most building codes require pans for water heaters installed in attics, upper floors, or above finished living spaces. Even when not required by code, water heater pans are highly recommended to protect against water damage from leaks, condensation, or tank failures.

What size water heater pan do I need?

Most building codes require the water heater pan measure at least 2 inches larger than the diameter of the water heater. Be sure the T&P (temperature & pressure) relief valve is within the diameter of the pan.

How do I connect to a drain?

Water heater pans can be plumbed to a drain using the provided connector. Your local building code may specify the type of fitting. Oatey water heater pans include either a PVC (Polyvinyl chloride) or CPVC (chlorinated polyvinyl chloride) adapter. PVC drain adapters fit over 1-inch and inside of 1-1/2-inch PVC pipe. CPVC adapters fit 1-inch CPVC pipe.

Why do some aluminum pans come without a pre-punched hole?

Aluminum water heater pans without pre-punched holes give the installer maximum flexibility to determine the exact hole size and best location on the side or the bottom to fit the available drain pipe. In some cases, a pan is intended only to contain a small amount of water or to have an alarm installed, rather than to be hooked up to a continuous drain line.

Which water heater pan should be used when installing a water heater?

The aluminum pan must be used for gas water heater installations. The plastic pan is not approved for gas water heater installations due to fire safety and temperature requirements. Both plastic and aluminum pans are approved for electric water heater installations.

What is the maximum temperature that plastic water heater pans can be exposed to before the integrity of the pan is affected?

The Vicat softening temperature is 180°F

What are the measurements for the Washing Machine Pans?

Outside diameter   29¾” x 31¾” Inside diameter   27-11/32” x 29-11/32” Depth   2-19/32”   

Does Oatey offer a washing machine pan without the ribs on the inside bottom?

Yes. The #34169 – 28”x30” pan does not have ribs.

Can the existing holes in the pans be plugged by the end user?

No. It is very unlikely that you would be able to create a watertight patch, and this would void any manufactures warranties. If you need a pan without holes for your application, we offer several pans for you to choose from: 22” Plastic Pans #34066 do not have holes stamped into them. Aluminum Pans are available without holes in all sizes.

What is the thickness of the aluminum water heater pans?

28 gauge or .032”
