OATEY 34174 26 in. Aluminum Water Heater Pans with 1 in.CPVC Adapter

The Oatey 34174 pan has a 26 inch inside working diameter, so it takes water heaters with a base diameter up to roughly 26 inches. Most 40 and 50 gallon residential tanks fall in the 18 to 24 inch range and sit in it with room to spare. Measure the jacket diameter of your tank, not the gallon rating, since insulation thickness varies between models.

Both. The 26 inch aluminum pan is rated for installation under gas or electric water heaters to catch leaks and condensate before they reach the floor. Aluminum construction is what makes the gas application acceptable, as opposed to a plastic pan.

It ships with a 1 inch CPVC adapter already fitted, so you tie into 1 inch CPVC drain piping and run it to an approved termination. If your rough-in is PVC rather than CPVC, use a transition fitting or solvent-weld adapter at the pan outlet.

Pan depth is a minimum 2.5 inches. That matters for two reasons: it gives real holding volume if the drain backs up, and it sets the height the tank sits above the finished floor, which you need to account for when you check flex connector and vent alignment on a replacement install.

It is formed from .032 prime aluminum, which is the standard gauge for water heater drain pans and supports a filled tank sitting on a solid floor. It is not a structural platform, so it should sit on a flat, fully supported surface rather than spanning joists or a gap.

The 34174 meets the requirements of the Southern Building Code. Many jurisdictions that require a pan also require a drain line to an approved point of discharge, which this pan supports through its 1 inch CPVC adapter. Verify the specific pan and drain requirement with your local inspector, since adopted codes vary.

Aluminum, like this 26 inch Oatey pan, is the choice under gas water heaters and anywhere the pan may see heat or need to resist deformation. Plastic pans are generally limited to electric tanks. Since the 34174 is listed for both gas and electric, it covers either replacement without a second decision.

The adapter is included. You order one part number, 34174, and it arrives as a 26 inch aluminum pan with the 1 inch CPVC adapter. What you still need on the job is the CPVC pipe, solvent cement, and any hangers or strapping for the run to the discharge point.

Listed product weight is 1.9 pounds, with a shipping volume of 0.647. One person handles it easily, which matters when you are stocking multiple units for a multi-family or MRO water heater replacement program.
