Winterizing water filtration system
Need advice. We live in a climate where we use our rv from time to time over the winter months. This is the first rv we have had with the filtered system. I need to know if there is a way to BLOCK this filtration system out when not desired? I will be emptying the system November 1st and tossing the present filter. I do not want to put another filter in the system until Spring. I use bottled water for drinking over the colder months.
The primary issue I see is that if the canister fills with water ( with or without a filter) the water in it is exposed to the freezing temps and therefore subject to freeze, expansion and case breakage.
With a bypass, the water is routed internally and gets the benefit of some furnace heat. I assume if I NEEDED to, I could place a corded lamp bulb next to the canister casing to avoid freezing? OR??
I am going to be using the rv again prior to the first freeze, AND, at that completion, I plan to do a dry run of winterization techniques so I am not fumbling for what is what knob, etc, while the wind is blowing and it's plain uncomfortable outside.
Thanks for all insight.
