Are you saying that you have lukewarm water throughout the entire house or just the shower? Does your shower valve have thermostatic control? N Back to you, Tom

That from the main and only geyser that feeds the whole house. Mark

Hi Eldon

No, the vacuum breaker has nothing to do with temperature or the overflow pipe leaking... ;)

You need an electrical tester and you first need to test the elements for continuity (disconnect wires from the elements AFTER shutting power). An element without continuity will need to be replaced.

If both elements test correctly then you'll want to replace the upper and lower thermostats as they are super cheap and quick to replace!

Good luck!
