CWH companion water heater — Product Manual
Troubleshooting (continued)
Water on the floor near the tank
1 Check for leaks from sources other than the water heater.
• Check for possible water seepage through foundation cracks. Did the water appear after a heavy rain?
2 Is the source of water from the T&P relief valve?
• Place a bucket under the discharge piping of the T&P relief valve and monitor it for a day or two. This is
a procedure that can be done by the homeowner.
• If the T&P relief valve is the source, refer to page 35 of this guide.
3 Loose piping connections or drain valve leaking?
• Check all connections – boiler connections, domestic connections, etc.
• Check all the boiler connections to the water heater. Check drain valve for leakage.
• A build-up of corrosion is a sure sign of a leak.
• Excessive force or water hammer can damage the welds where the piping connections enter the water
heater tank. Remove the front of the CWH enclosure to check tank and connections.
• If water is leaking from around one of the tank connections, a weld may have been broken. Contact
your Weil-McLain supplier to determine how to handle the problem.
