I have a under sink waster heater. the model is the atlantic 10LU Model. This is new. And started to leak after installation.
There is a discharge coming out of a hole all the time. I had the installer in to look at it. He did a fix but the problem persists. I read here about how to empty the contents of the heater till i can get him in to have a look again and hopefully replace this time as maybe the unit is faulty:
What i need to know is how would i recognize the discharge valve. Also in work we have a similar heater. I noticed the hole in the heater in work is plugged with some sort of putty. Is the hole supposed to be plugged?
