Marathon Hot water heater drain and access

I have done several forum searches and cannot find- how to access the water heaters, and how to drain. need to figure outgood way to winterize as I do not have heated storage here in Colorado (yet).

Thanks

Can you access the hot water heaters? Marathon and Country Coach installed two 12 gallon hot water heaters. If this is what you have, they have drain spigots on them.

I do not know where they are - or how to get to them. The Marathon has the large panel with all the water circuits with individual shutoffs on that panel. That panel looks very involved to remove.

Water heaters should be directly across from the water bay cabinet that you referred to, in the curb side bay.

Just open the pressure relief valve.

got it- Thanks to all. In the past on other motor home I put air into city water supply and blew out lines, after draining water heater. then poured rv anti freeze into traps.

For Aqua-Hot owners that must winterize, don't rely on blowing the water lines out with air. Water tends to settle in the Aqua-Hot coil. If this copper line burst your repair could be around $10K. Aqua-Hot dies not sell that as a replacement part.
