Question

New WH Leaking Water Into Electrical Box


Bought a 40 gallon Rheem water heater and installed it myself. No biggie, done several in my life.

Two days later the breaker popped. I opened the cover to the compartment on top of the WH that houses the electrical connections. It was full of water!!

Where did it come from? No water on top of the WH at all. Nothing leaking from the input or output water connections.

(Tried posting a photo but I'm new and it said I needed 1 post first.)

I cleaned it all up, redid the wire nuts and put some silicon in the opening where the wires go down through the bottom of the box. Closed up the top of the box and have not had any problems for several months until today when the breaker popped again.

I heard the "POW" this time and sure enough, when I opened the cover the box was full of water again. WTF???

Where is this water coming from? Why now after two months?

I've opened up the element panels but don't see any water there. I verified that no water is coming through the electrical conduit.

Look at that rust in the water! This was two days after purchasing the unit. ????

Has the heater recently been shut down and allowed to completely cool to room temperature or below normal room temperature?

looks like corrosion on the armored cable. Your just going to have to keep examining it closely to find where the leak is.

Keep an eye on it. Try to figure out where it's coming from. If it turns out to be the wh itself that's leaking, rheem is a very reputable company, I'm sure they would replace it at no charge.

Check it out after different intervals of use.

Check really good around the inlet/outlet area and fittings with a flashlight. You may have a small drip that is somehow finding it's way to that electrical box on top of the wh.

If you're talking about the "whiteness" on the conduit, it's paint.

Done that. No leaks. After it first happened a couple of months ago I checked quite often. Never saw a leak.

Wow. That's a head scratcher. Call or go online to the manufacturer and explain to them the situation, maybe they can help.

Maybe there is a hair line crack in the tank itself somewhere and it doesn't show up until it reaches a certain temperature/pressure then it leaks. Very rare and not likely, just a suggestion/guess.

Hope you find the cause soon. I would very much like to know the cause when you find out. Please post the final outcome. Thanks.

Call rheem and send them the pics. Most problems don't happen only once. If Rheem has a low incident of leaks that occurs sporadically in this area of the tank they will know about it.

You probably have isolated instances where the tank get's pressurized just a tad more than normal. Just enough to allow the slow leakage and then go away for a while.
