water heater leak

[Wyo_hunter]

Just after I mistakenly turned on the water pump while the city water was hooked up I had a leak coming from the water heater. It was a jet of water coming from the insulation cover around the heater. GHas anyone ever experienced this?

You have a simple leak at the water heater, either a fitting connection or at the tank

One of my previous TTs had a water leak - behind its hot water tank. Turned out to be a loose fitting - that probably became loose from normal road vibrations and/or trailer's natural twisting. I simply hand tightened the pipe connection again (maybe 1/2 turn) and the leak immediately stopped. Have you performed visual inspection of the back of your HW tank area via little mirror on end of a telescope rod? Just wondering...

As noted......pump on at same time hooked up to city water is a NON-ISSUE

Leak from insulation cover means it is on backside of water heater so I would also suspect a water line fitting/nipple

But more info/details would be helpful

Have not had a water heater leak. Must take insulation off to locate the leak.
Your water pump had nothing to do with it.

Why I'm curious about the age and make of HWH. Sounds like a failed fitting but could be a failed tank as well.

Turning on the water pump while connected to city water will not hurt anything. It sounds like you have a leak at one of the fittings where the water lines connect to the water heater. You need to get a good look at where that stream of water originates.

Do you have a pressure regulator on your city water connection? I have seen water pressure as high as 110 PSI at campgrounds. You should have a pressure regulator to keep the water pressure around 50 PSI, or whatever pressure your water pump shuts off at.

Little more information would be helpful like age of unit and make of heater...
