I have a 2003 Monaco Exec 40 ft. The Aqua hot was not warming the living area or the bathroom, the bedroom was toasty warm. Took it in and they found one leaking pump out of 3 pumps. They replaced it ...
A paper clip comes in handy to keep papers together. AND, to reset your Aqua Hot system if it's needed. There might be people who didn't know about the reset button but they do now :p
