Problem:
5. Heat exchanger visibly leaking.
a. Cause: Plumbing connection loose.
Solution: Check and tighten plumbing connection.
b. Cause: Double-wall heat exchanger tube leak.
Solution: If one of the tube walls is breached, a double-wall heat exchanger will leak at the joint between
the tubesheets. Isolate the heater and replace the heat exchanger.
Since PVI cannot control the use of the water heater, water conditions, or maintenance, the warranty on
the heat exchanger does not cover poor performance, structural failure, or leaking due to an excessive
accumulation of scale
