De-winterizing 2013 3170ds Sunseeker

I Just bought a 2013 as 3170ds. The dealer did not offer much info on de-winterizing the unit. We are headed south in a couple of weeks. Looking for info on de-winterizing once we are in SC for a night before heading to Florida. I do not plan on using the fresh tank . any info will help

It really depends on what they did to winterize it. Assuming they added antifreeze, it's mostly just a matter of hooking up to water and running all the taps (sink(s), shower(inside and out), toilet) until it's clear. Then turning the bypass on the water heater back to normal usage and possibly putting the anode/plug back in the water heater.

De winterizing.

This is relatively easy to do compared to the reverse. There are good videos on YouTube that explain the process. Important to make sure that you do not let antifreeze into the hot water tank. Hook up to shore water and run all taps and shower until it runs clear. Only then do you return the hot water to normal settings. In my RV... There are three valves, two to shut off the hot water tank and a third to bypass it. Assuming it was done correctly. All you do it shut off the bypass and open the inlet and outlet to/from the tank.

Winterizing is the opposite procedure but includes draining all tanks. A little more touchy since this is where a mistake could cost you.

Good luck and safe travels!

Don't forget to run any outside showers or water ports, rinse the washer/dryer lines, and water dispenser/ ice maker (if so equipped). After rinsing all lines, open the low point drains to make sure all antifreeze is out.

After you flush the water lines until you have clean water running out of the faucets, be absolutely sure the water heater is full before you turn it on. If it's not full, the electric heating element will burn out in seconds.

Also, do you know when the fresh water tank was last sanitized? You may want to flush and sanitize it yourself. There are discussions about that in this forum.
