We have an ISOTEMP slim square 4.2 heater which is leaking. I am talking a slow drip from the front at the bottom. Over a 24 hour period we have about a 3 or 4 oz. accumulation, which is being collected in a small drip pan in order to monitor
the amount. It is so slight that the fresh water
pump might come on once a day for a very short cycle to compensate. The leak seems to increase when the 110 power is turned on. The leak is fresh water
, not engine coolant
, and is very clean, no sediment, no corrosion
, evident. We have removed the small gray plastic cover on the front, to check for obvious leaking fittings but found nothing. One or two of the six bolts housing the element was slightly loose and was tightened. In order to go further we will need to remove the large white plastic front cover, which will nessitate the removal
of the heater and all associated attachments. Would like to know in advance if we would likely find any repairable item behind the cover. Thought about just cutting away the cover as it only seems to serve as dress up item.
I have searched the net for information on possible trouble shooting ideas, or break down views, with negative results. Has anyone run into this issue? The heater is about 7 years old, and works like new and produces clean hot water. A new one is many coins, and only this type will fit.
