Blowing Lines

Just did mine yesterday. I do both. Blow the lines & add the pink.
My thought is blowing the lines may leave some water, even just a few drops around the spigot's or toilet flush valve and it would freeze & bust. Most all RV spigots and flush valves are all plastic. Its just as easy to pump the pink as blow the lines. Put the hose in the gallon jug & turn on the pump & open each spigot. Spring just turn on the water & flush.

Air & Hydronics don't go hand & hand. I just flush out my lines with the pink stuff.

Just did mine this morning. I usually fill a 5 gallon bucket with 3 gallons of pink, drop my fresh water pick up hose in it and let the pump suck it out and fill the lines. This time I drained the lines first with the low point drains. The only difference I noticed was I saved about a 1/2 gallon because I didn't have to make sure all the water was out. Either way I'm good for the winter. Oh, ya, I did put some down the drains also. Enough to flush out the water from the traps.

I do it in the opposite order. Run a couple c=gallons of pink stuff through the lines then blow it out.Much less of the pink stuff to flush out in the spring. Blowing out the lines fills all the traps. Just add some to the toilet and done.

One trick I learned for better line draining was to use the leveling jacks to "rock" the coach from side to side, front to back, etc., with the faucets and low point drains open. A few minutes doing that and I see very little water when blowing out the lines.

Well then you would be wrong. Northern Alberta -40 not uncommon. Been blowing out for 15 years without issue. What dii does it make if its -10, 20, or 40? Frozen water is still froze!!

Adding the pink stuff is good marketing and just makes you feel better.

Nope! Adding the pink stuff is doing the job right. And it makes me feel good the job is done correctly!
