To Blow or not to Blow.... winterize waterlines?
Well... its that time of year to winterize my waterlines.
Only the 2nd Winter for me with any type of RV.
Last year I use the Walmart Antifreeze.
This year I am just thinking of using my Air Compressor and Blowing the lines out.
Can you all please refresh my memory of the Pros and Cons.
Thanks...

We also use the pink stuff. However, make sure you get unflavored/unfragranced pink stuff. One year, with our previous motorhome, we bought some pink stuff at our local hardware store, and it advertised a pleasant taste. Not! The next spring, after 4 fresh water flushings, we could still taste it. We then did vinegar, followed by another flush - almost there. We then did baking soda followed by another flush. Finally that awful taste was gone. Luckily we were staying at a campground where the owner realized we were only dumping fresh water!

Can that potential problem not be solved by hooking up to the antifreeze jug as normal and then running the pump for a short boost? Seems like it would put enough antifreeze into the pump to displace any possible water.mockturtle wrote:I just use the pink stuff. Seems to me that the only 'con' to the air-compressor method is that the water pump may not get cleared.
Just a thought

If blowing out the air lines is your desired way, I recommend reading Mike & Jean Bandfield's reply to a similar post:

It gives very precise instructions on how to perform this process properly. I have never done this, but the post is quite detailed.

I was briefly thinking about blowing out my water lines this year instead of using the antifreeze. Honestly, it is so easy to put the antifreeze in that the thought of blowing out the lines blew right out of my head.
When I thought about it I would have to buy the adapter, get my compressor out, I think I would need a different air chuck.....The antifreeze is only $3 per gallon at Wal Mart (I just bought mine). I didn't notice a taste, but then again I did a thorough rinse at home with bleach before I went camping in the spring.
I can winterize in less than 10 minutes. Hook up the hose to the water pump, put it in and run it till it's pink.

winterize
You should only use a compressor that uses no oil.Oil lubricated compressors can contaminate your water system.

Blowing out water lines
I've blown out the lines on our BFT for 6 yrs. now with no problems, and we live in Wi where temps get down there. Just have to make sure you hear air coming out of all faucets, and put a little antifreeze into water traps. Regards the water pump, after blowing out the water, I run the pump a little, then take off the small sieve and dump any remaining water. FWIT, I find this easier, less costly, and quicker to fill in the spring.

I have used the compressed air route for years. Yes, I worry about the water pump, but have found that waiting until tomorrow to re-blow the system will allow any drip to get to a low point that will be blown out. We live in the foot hills of Northern South Carolina where it seldom gets very cold at night. When the prediction is for way sub-freezing weather I just put a shielded 60 watt bulb near the water pump over night, which is probably unnecessary.
The concern about rupturing a water line with air pressure is unfounded because an open faucet will not let the pressure rise to dangerous levels no mater what the input air pressure is.

Small amount of water in the piping system is harmless. It freezes but does not do any damage (for example the water heater tank contains always some water left). As far as the pump is concern, blowing air and running the pump evacuates enough water, so no damage could occur.
Very recently I built a trap (1.5" PVC pipe), filled it with water and put it in the freezer. The ice expanded alongside the pipe and did not rupture anything.
So it is more than enough to drain the system driving with all spigots open (it safes time). And to be on the safe side, blow with with 45 psi air and put some of the Wal Mart stuff in the traps. With spigots and drain valves open the BF can go safely for storage.

I personally like to use RV antifreeze to winterize my Born Free and have done it that way for the 8 years since I have owned it. My coach came equipped with a winterization hose made up of a 3' length of 1/2" surgical tubing with a right angle connector on one end to hook up to the input port on the water pump.
See the two attached photos below.
a) Drain the hot water heater and then place the associated 3 valves in the bypass position.
b) Then turn on the water pump and open each hot and cold faucet and each floor drain one at a time until the pink antifreeze flows out. Make sure that the water traps in all sinks get antifreeze in them. Run both hot & cold faucets in the shower and also the outside shower hose if you coach is so equipped.
c) Don't forget the toilet rinse hose valve also.
d) I can winterize my Born Free with 1-1/2 gallons of RV antifreeze

Thanks everybody.
I will probably just go with the PINK stuff again, although the AIR is intriguing. I could still taste the PINK in the spring.
The thing I don't understand, why winterizing can't be more simple?
Why aren't the MH water system designed to Drain just by GRAVITY?
And could work like this:
Close WH valves, and Bypass WH. Unscrew drain plug and drain WH.
Open up all the facets to allow air in system.
Open up all floor drain valves.
Run the Pump briefly, to run dry. Maybe undo 1 line to Pump?
Pour Pink in all the traps.
Why can't it be this simple? What am I missing? Thanks Again...

Steve,
If you look at all the water lines in your Born Free, they lie flat on the level floor under the cabinets, etc. In order for gravity to do what you want, both the cold and hot water lines would have to be elevated in a curved fashion with the low points being two master drains - one hot water and one cold water. Well, I doubt that it would be reasonable to have a curved rather than a flat floor or to elevate the lines and water pump in a curved manner.
Actually, in addition to the simple steps you list in your post, only the extra step of connecting the 3' adapter hose to the water pump's inlet port and to a gallon of pink antifreeze would be necessary to complete the process. Simple enough in my opinion.
