The hot water check valve is the bane of my existence. Well, one of the banes anyways. The legacy story follows.
First year, when winterizing, put the valves in the configuration to bypass the hot water tank. Pink antifreeze flowed in anyways. Diagnosis: Check Valve malfunction. Corrective action, sanitized the day lights out of the hot water heater. Then used compressed air to dry the lines before winter (inside) storage.
Last spring, had check valve installed by my selected service shop. It took a long time to run hot water to sinks (see my gallery tank post for probable consequence). Not only that, running hot water made squealing air noises all season long. Hindsight, - check odd stuff out.
Backstory: The former owners enjoyed extended dry camping. To the point of removing the water filter and pumping water from a nearby stream. Consequence - gravel in the freshwater tank? Determined by the fact that last year, the faucets in the kitchen and bathroom sinks would not work. Finally, took the faucet aerator off and dumped out the sand.
This season, all valves in the right position, hot water heater on, and no hot water after a long time of running the freshwater into the gray tank.
Options as I see them.
1. Put an inline water filter back on, just on principle and practice alone.
2. Remove the check valve completely, I'm good with drying the water lines out with air every fall.
3. Remove the check valve completely and spend winters down south. (A few more years of full time employment are required before exercising this option.)
