Freeze Check After a Long Hard Winter

Ok, now that this severely cold winter is wrapping up, and we start to get our RV's ready for the coming season, can we report in this thread; How your RV's plumping system fared?

Reply, how you winterized, 1. Air blowout method, 2. antifreeze method, or 3. Other. And what the damage, if any, you incurred.

I am curious how we all held up this winter, seeing it was one for the record books, and surely will lend some useful data for all of us to use in the future.

Our winters here in central Texas are mild as compared to what some parts of the country have experienced tho ours was colder than "normal"this year. When I needed to winterize I blow out the lines, drain the water heater and tanks and add the antifreeze to the traps. This year we were lucky and spent January in So. Florida. Normally I winterize 3 or 4 times a season as we camp year round as the urge hits us. Had to winterize when we returned to Texas in February. If I lived in the North the entire plumbing system would get the pink stuff not using the RV till the snow melted or just head south, we are Retired.

Welcome to the forum!

3. Other=Both. Blew the system out, drained HWH, bypassed HWH, flushed with antifreeze. My system was still under pressure when I traded it in.

Antifreeze protects the low points and inside the faucets, I blow it out with air to make the antifreeze process easier.

What kind of RV do you have? I have a Solera 24S I do a drain followed by a blow out then fill with anti-freeze. Of course I close the WH by pass the remove the water filter. I just de winterized my rig, flushed the system with water then because of the continued cold weather I blew the lines out with air and dumped the traps on the sinks.

Our winter was the typical long and cold.
There were some -30's celcius.
Not sure that would make much of a difference once it hits -10/-20c.

In a few more weeks I'm about to find out how my winterizeing faired.

First I by-pass and drain the HW tank first.

I usually run 4 gallons RV anitfreeze through the system. I know thats more than needed but for the additional $5/$10 I'm running it through.

Once all the antifreeze has gone through I open the low point drains, open all the taps, just to make sure there is no presssure in the line and then I open all the tank valves. I have a pail to catch all the draining.

Then I spend the rest of the winter thinking..........did I do the.....


Oh yes, Welcome Still Kickin.

I think we understand the process of winterization, the point of this thread is to get some feed back on what, if any, damage was incurred, from the method used in winterization. The purpose is to try and determine which method, due to the severe cold winter, worked the best.

I belive that the extreme cold temperatures expierenced, lends itself to getting data we can all use in the future.

This is not meant to reply back which method, or how you went about winterization but rather, which method and what was the outcome after getting it ready for the upcoming season.

Well, correct that, Yes the method is important too. But I think knowing if one seems to be better than the other, taking into account methods (proper procedure) is important to reply back as well.

Chicago/Chiberia.... Used the blow out method. Started blowing farthest from the air inlet up to the outside flush station. Pulled the zinc plug from the water heater, just left it open there. Oh by the way most refer to a hot water heater? Do they make a cold water heater? Removed the factory water filter and bowl assembly, just left it open there too. Put antifreeze in the drain tanks/S-Traps. Even pulled it to the repair shop three times this winter -15F. Filled her up and turned on this week. Absolutely no problems. Thank you Lord...
