A Few Tips for Upcoming Cold Nights

In the spirit of this weekends roundtable in Alabama, I realize that what we do all the time we sometimes take for granted, and assume that everyone knows what we do. The following may be common knowledge to many, but a few guys may really benefit from it.

During this time of year daytime temps in many areas are becoming great for our line of work, however nighttime lows drop below the freezing mark. So if your like me and you keep your equipment outdoors in an un-heated area you may have frozen lines to contend with. Frozen water in lines you need clear the following morning for a job may be an issue, I hope to help with this one.

Since everyone's machines are different, I'll focus mainly on lines. When clearing a water supply hose (garden hose) I blow the hose clear using my air compressor with a regular 1/4" male air fitting, a male pipe to FIP hex bushing 1/2"x1/4", and a male hose to MIP adapter tapped 1/2" FIP 3/4"x3/4"x1/2". All seen in the pic. This screwed onto your hose will push all water out of the hose, reel, and jumper into the tank.

For the high pressure lines I use again use a 1/4'" male air fitting, 1/4" x 3/8" adapter, with a 3/8" MPT plug attatced to the coupler. Unconnecting the jumper from the washer unit itself you can totally clear the high pressure lines.

For the water supply line from a buffer tank, I cut off my supply line next to the machine and empty the in-line filter. On my set up I open another valve at this time that supplies the washer itself with antifreeze from a self contained resevoir. Now back to the water supply line. I put a 3/4" T-fitting coming directly out of the tank, one line supplies the machine, while the other I use for a dump valve to empty the tank. I drain the tank and elevate the supply line so that all water is cleared out of the lines.

Doing all this makes it easy for an early morning job the next day. Just one time of stretching out hose and using a blow dryer will have you wishing you did this.

If anyone else has any other ideas for a nightly cold snap, or improvements on mine, let us all know.

Yeah one time was all I needed to learn to blow out my supply hose. I also had Pressure Tek install a blowout valve on my skid unit. First all the air pressure goes to blowing out the bypass hose back to my buffer tank. Then I have a ball valve in the bypass hose I cut it off. Then all the air pressure blows out my pump, heater coil and hose, blow it for a while. Then as added insurance, I undo my short hose at the reel and I have a 5'er with Windshield washer fluid. Run this thru till it comes out the jumper hose then I blow all that back into my 5'er of fluid and save almost all of it to re-use. I need to get some pics of this setup posted. This lets me sleep easy on cold nights. I probably ought to use regular antifreeze or RV antifreeze but the WW fluid is good to 0 degrees I think. I feel the anti corrosive in regular AF might be better though. I usually see a lot of rust in the first gallon or so of water when I start up now? :confused:

I'd thought about doing that Pat, but the only thing I'd be concerned about is initially firing up the unit with nothing in the pump whatsoever which may lead to trouble later...maybe???
