First we live in Florida and it’s been hotter than normal lately.
My wife complained that the cold water was no longer cold but warm. Yep I ran the cold water in the kitchen sink and it felt warm.
I suspected that perhaps the hot water circulation pump that uses cold water return had turned on without be commanded. So I pulled the plug on the pump and turned off the ball valves on the pump. Ran water for 5 minutes and it still was cold. WTH?
Got to think if there perhaps could be some crossover in a shower balancing valve, or feedback from water heater, so I’m went to my water heater that has a tempering valve connected to it and shut the water off to the HW tank gate valve.
Ran cold water in kitchen for 5 minutes and it still felt warm? Now I’m confused.
Ok now I go outside and turn on the outdoor hose spigot connected to the house entrance and it too felt warm. Ah Ha.
Ok now I get my digital meat thermometer and measure cold water temp at sink. It’s 81.3 degrees. I let it run and it remains at 81 degrees.
So I go outside and check water from street. It’s 81 degrees.
This morning I run the water and it’s 80 degrees and it no longer feels warm, but normal Florida cold.
ONE DEGREE difference made it no longer feel warm.
