For all the issues we can have with boats this is low on the to do list but looking for some thoughts on the cause. I noticed that when I turn any of the sinks on in the boat I get cold water for a few second then it gets warm to hot for a few seconds. if i let it run it will cycle like this entire time with only the cold water side on. Only thing I can think of is that the mixing valve on the hot water heater is back flowing into my cold water supply?
Thanks
