New TT owners - When to Winterize

The weather is weird and getting weirder all the time. For the roughly $10 some pink stuff is going to cost - unless you drop a gallon on the ground and have to get another - and probably less than an hour of work, I'd do the whole job and know it was safe. Come March or whenever, you may wish you'd made that little investment. And, IMHO, now would be good.

I use one of these....

Harbor Freight Inline Air Regulator with Gauge.

Actually I have found that around 10PSI is nearly ideal pressure. Any more and it seemsmto me that water can stay in the lines

I use one of these 12VDC tankless air compresors which takes time to come up to pressure... This seems to be just right for me...


I hook this up to the city water connection point using one of these air adapters (AMAZON)



Of course my trailer is a small trailer with minimum water lines etc... The BLOW OUT method works great for us as we like to camp late in the cold season. We can drain our fresh water tank, blow out the water lines, and fill the P-TRAPS with some pink stuff pretty quick. Then the next day we can use our water system again by just adding water to the fresh water tank...

Our winters here in Northern Neck Virginia are not all that long term. Usually warms up great during the day time hours...

In my working years I spent alot of time in the North Texas Wichita Falls area and boy when it got cold it was really cold there haha... Road freezing was a hugh problem for us but like you say it usually warmed up pretty quick the next day... Of course when the Blue Norther comes thru its Katie Bar the Door for sure...

Your compressor should have a knob somewhere near the psi gauge where you can turn up or down the pressure. If there's no gauge, just make sure all your faucets/showers/toilets are open and I'd think you should be fine.

In Dallas? Heck I would only blow the lines out with compressed air and plan on camping year round unless there was snow on the ground. A cup of RV antifreeze in each "P" trap and the toilet should be more than sufficient after blowing the lines out.

I found a post similisr to mine below so sorry for the "repeat."
