Winterizing question

[Cavi123]

So this is my first time winterizing our x17z I had it done at the dealership and they showed me how to. My only real question is leave antifreeze in the water lines or blow air through. I have heard from multiple sources that leaving it in the lines will leave a taste in your fresh water that you can never get out. Anyone have any thoughts or feed back? Thanks in advance

Blow the lines out first.


Fill the system with NON TOXIC (RV) antifreeze and leave it in for the winter


Sanitizing the water system in the spring will flush out all of the antifreeze.

I just finished winterizing my 24RKS. I have always left RV antifreeze in the lines over the winter and never noticed any bad taste in the water the next year. You just have to make sure that you flush the lines good in the spring. Make sure you close the valves for the water heater and open the bypass. You don't put antifreeze in the water heater. Just pull the drain plug on the heater and open the pressure relief valve and the water will drain out.

you can leave it in, I recommend flushing the lines for a bit longer, and I always sanitize the lines in the spring, which takes a bit of water to get the bleach out too.

I do blow the lines out after installing the antifreeze, not for taste, but for added protection incase we have a terribly cold winter.

I leave the pink stuff in the lines, but not the hot water heater, that gets bypassed and drained. In the Spring, I fill the fresh water tank and run it thru the lines and let sit for 3- 4 hours. I then drain the fresh water tank and refill it couple of times and run the water thru the lines each time.

Agh...yes, my bad, yes, i was not wearing my glasses when I typed my response and just re-read it now. Thanks for correcting me, i meant to say the first tank in the spring is a full tank of a bleach solution that is run thru the lines to sit for 3-4 hours and then drained. Refill with fresh water, flush the lines, drain tank. Repeat this process 2-3 more times.

Keep in mind that all pink stuff is not the same. Stay away from the alcohol based products; I hear that they are the ones that leave the bad taste. They will also dry out rubber seals, blade valves, faucet valves, etc.

Use a propylene glycol product. It will cost a buck or two more but is worth it; good lubrication on all your valves. I use Prestone; I'm sure there are others that make it. I'd also stay away from propylene glycol/ethyl alcohol mixes.
