antifreeze

Chesapeake · Approved Exterior Cleaner

We blow out all lines with air, and run washer fluid through the pump, cut at 50/50. Cutting at 50/50 is good down to 10-15 degrees.

Art I use the RV anti freeze, After the pump is cleaned, I run it through and recapture it so I can use it the next day

I think I'm going to try that West Marine pump antifreeze this year. It has a lubricator in it for the pump.

I found that 50/50 is cheaper then straight antifreeze.

I guess West Marine is bigger than I realized. I replaced the VP's roof a couple weeks ago.

Good tip. How'd you figure that out?

Thanks Ed. I should point out that my 50/50 solution is made using -20 washer fluid. This is the one most commonly sold in my area.

This list shows the approximate amount of methanol in the different types of washer fluid. The -20 cut to 50/50 will have 17-18% methanol which will get you safely in the 10-15 degree range. I believe this mix will withstand freezing down to 0 degrees, but it could start to slush.

+20 F Washer Fluid - Contains approximately 7% methanol.
0 F Washer Fluid - Contains approximately 23% methanol.
-10 F Washer Fluid - Contains approximately 28% methanol.
-20 F Washer Fluid - Contains approximately 35% methanol.
-25 F Washer Fluid - Contains approximately 38% methanol.
-50 F Washer Fluid - Contains approximately 62% methanol.

Hello all,

If you are winterizing your pumps be careful what you use because it can cause premature ware to your packing's and or dry out your o rings on your brass and valve seats. I use to run rv antifreeze and blow out the excess if it pools it is like not flushing the chemicals out after washing.
