Winterizing my Clipper 107 Sport

[Gregpietsch]

I got a 2006 Clipper 107 sport this summer and it is time for me to winterize it. It only has cold water. The manual says drain the water tank and then add 2 gallons of RV antifreeze and run the pump until the antifreeze comes through.

I stopped by the local RV shop this morning to pickup some antifreeze and they went on a rant about how I shouldn't add this to my fresh water system because I would never get the taste flushed out (The product was listed as no taste, non toxic). Is there indeed a problem with adding it to my tank and pumping it through? I have seen youtube videos where people have connected a line to their pump to pump directly into their lines. I don't see how this is too different from adding it right to the tank?

Thanks for your help

No problem..........just turn on the bypass valves near your water heater to bypass the heater itself.....you don't want RV antifreeze in your water heater. In the Spring just run a small amount of bleach through you water lines to sanitize your system, after you flush your lines with fresh water.

Thanks. Can I drain the excess out of my freshwater tank or should I leave it in there over the winter?

Drain fresh water tank, leave valve open. A small amount, around a few ounces may settle in a low area, but when it freezes it will not cause a problem.
And do NOT add RV coolant to the fresh water tank. Take forever to flush; or so I was told.

In the spring you may also want to sanitize the fresh water tank. I use a cup of household bleach for my 20 gallon water tank every spring. I let it sit for about six hours, then run for a few minutes through the water lines and heater, then drain both tank and heater.

Then I flush both the water tank and heater a few times and never had a bad taste or a bleach taste in the water.
