Winterization Question

I know its early for this question, but here it goes anyway. Just finished the job using the winterization port everything went well. I am curious, when you use the port for the antifreeze, I maybe wrong on this but you can't get the antifreeze in the water line that fills the fresh water tank. If I am right how do you do this, or is it not necessary? Thanks in advance!

We primarily blow out lines and put a little antifreeze in the shower trap. Can't see the need in the fresh tank.

The antifreeze would not go into the line from the winterize switch to the fresh water tank. I don’t know if that line would self drain back to the fresh water tank when you drain that tank or not. But that is not a line you can blow out either.

Our winters are not as cold as many of you. But temps in the mid to low teens are not uncommon and we have never had a problem with that line.

You can get antifreeze into the freshwater supply hose by using this same method (you only need to do it for a few seconds though...

Filling freshwater tank using winterizing port.
Take 5 gal bucket of freshwater. Connect a pickup hose to the winterizing port (sometimes you have to use 2 washers to make a good seal). Put the open end into the bucket of water. Turn winterize valve to "ON". Connect the shower hose to city water connection. Turn "Normal flow/Fill" valve to "Fill". Turn water pump on and open cold water side of shower. Water will draw from 5 gal jug go thru shower hose into city water connection right into tank.

This is exactly how I do it too. Except this is next to the last step. Last step is the ice maker on the refrigerator. Why last? Because if you do this one last, the lines will be filled with antifreeze up to the shower (or that blue hose thing). When you connect to the fill port, the pink stuff is immediately pushing the clear water out. I also open the fresh water tank and have let it drain completely. I then watch the water coming out of the tank. As soon as I see the slightest hint of pink, I turn the faucet off so no more pink stuff goes into the fresh water tank. I then let what remaining (little bit) of pink stuff is in the tank drip out. The amount of pink stuff in the fresh water tank is minimal this way and drains all out. When unwinterizing, I simply hook up the garden hose and flush the line with the fresh tank draining. Once the fresh tank drain runs clear, it's pretty much done.

I also do this with the water heater. I'll drain the water heater in by-pass and pump the pink through everything. Then, with the drain open in the water heater, I'll undo the bypass and wait for the pink to flush out the water heater, then put it back in by-pass. Later, I'll go back to the water heater and rinse out the pink stuff sitting on the bottom of the tank with a small wand attached to the garden hose. Wait for it to completely flush out the pink, let it finish draining again, and then put the anode rode back in. What little water is still in the bottom of the water heater, if frozen, will never hurt anything as it has 10 gallons of space to expand.

Come Spring, I'll unwinterize everything, and then open the bypass with the water heater anode out again and flush the line and water heater until all pink is gone.

I have very reliable power and live close to where our RV is stored. I have about 14 drop lights, I put two every where something could freeze...toilet, refer, heater, water bay, etc and put pink stuff in the P traps. I use two each in case one burns out, plus if really cold, I check on them. Been doing this for many years without a problem.

I blow that line out with air. IMO RV antifreeze does not taste good; I don't want any of it in my fresh water tank; too hard to get out.

I find it better to hook up in Oct. and head South to where freezing is not heard of.

How far south? I live in Florida and we usually have freezes every year. It's been pretty mild the last few years, but I have seen single digit temps. Lived there for over 55 years.

The rule of thumb is that you have to be below I4 to avoid most freezing temps. We Winter approx 50 miles South of I4 and in the last 10 years I think it's only gotten below freezing a couple of times.

I have wintered in Florida several years and have never seen daytime temps below freezing. It may drop below 32 for a few hours at night but all that would freeze is the outside spigot.

I'll usually drain, blow it out then add the pink stuff. While PEX is a lot more forgiving then the copper tubing that was in our Kountry Aire years back, the fittings aren't, I normally use the shop compressor but have used my Porter Cable pancake unit as well.
