How to Measure and Install a Water Heater Pan

Now that we've discussed the fundamentals of water heater drain pans, you might be curious about how to install one to safeguard your home. First and foremost, ensure that you have the appropriate tools on hand.

You will need:

  • A measuring tape
  • A drill (if your water drain pan lacks a pre-cut hole)
  • A pipe cutter
  • The water heater pan

Step-by-Step Installation Guide

  1. Measure the diameter of your water heater.
  2. Select a pan slightly larger than your water heater's diameter to allow room for a drain fitting to be installed.

Note: Be mindful of the pan depth. It should be deep enough to contain approximately three or four gallons of water. It’s also essential to have a slight clearance around the sides of the pan so that drain fittings and adapters are accessible.

  1. Place the pan beneath the water heater, making sure your drain fitting is accessible.
  2. If your water heater pan does not come with a pre-cut hole, drill a 1-inch to 1-½-inch hole for the drain adapter. The size of your hole will depend on the drain adapter.

Oatey® Water Heater Pan Adapters are available with 1-inch and 1-½-inch PVC or 1-inch CPVC drain fittings to allow for connection to an indirect drain.

  1. Run the pipe from the drain pan to the drain.
  2. Ensure all connections are tight and there are no leaks.

Remember, a drain pan is a layer of protection, not a solution to water leaks. Addressing the underlying reasons for water in the pan is essential to safeguard your home and maintain the effectiveness of your water heating system.

Installing a water heater pan is a proactive step in safeguarding your home. Neglecting this crucial component can result in expensive repairs and potential health hazards. Protecting your home starts with this straightforward yet highly effective measure.
