…

11

Thank you!

12

You answered your own question. It’s not a water heater problem, it’s a water chemestry problem.

13

I guess you could look at it that way. But the “problem” originates at the water heater. Without a water heater there would be no “problem”.

14

Congrats Tim!

Although my sour grapes comment is that gray is a recognised and acceptable color for the grounded conductor…

15

Your not going to fix it by fixing the water heater - you can only fix it by fixing the water chemistry.

16

Yes sir Steve!
Just like any test/exam, you must be able to efficiently READ the question.
The question started out incorrect.
Congrats Tim! :smiley:

17

Tim’s in Michigan. There’s no fixing that water!!

18

Correct. But water heater was never entered into the question. Congratulations winner.
The questions about water chemistry.

19

Help me understand ~ “water heater” was entered into the question.

20

Even though the water heater was the culprit in this Sherlock Holmes mystery…
The essence is about …reaction of sulfates and microorganisms that create Hydrogen Sulfide .
That could happen anywhere in the system, be it the WH or anywhere else in the system.
It could happen in the well tank and beyond. It doesn’t have to be just be the WH.
