I notice that in late Fall, when temps drop, there's an uptick in leaking refrigerator water feed lines, and then in the Spring, when units are de-winterized, there's another uptick in leaking water feed lines.
An easy to overlook part of the winterization process is to evacuate water from the refrigerator's ice maker water supply line. Specific steps must be taken that are in addition to routine use of RV antifreeze or compressed air. If by chance this was overlooked when your unit was winterized, the poly line will certainly freeze and crack. The next time you use your water system, you'll have a leak.
If you have a residential refrigerator, consult our owner-written
Residential Refrigerator Guide. If you have a traditional gas absorption RV refrigerator, the owner's manual should cover winterization procedures for the refrigerator, but may not provide guidance on the water line. Reading the
Residential Refrigerator Guide may help you take the appropriate steps to protect the water line.
