Battery Transfer pump for antifreeze

I use a manual pump to winterize my class c, works ok, but thought I would see if a battery powered transfer pump that would connect my RV was available.
So far I haven't found one - anyone tried such?
  • Just use your own water pump. Remove the suction from the storage tank to the pump and then connect a plastic tube to the suction side of the pump. That's all you need. Simple, quick and easy. Your only expense is for a short length of plastic tubing and a barbed fitting to match your pumps suction side. When finished, put the line from the storage tank back on the pump and store the adapter you made for next winter.

    Have one as well. Cannot beat the 10 buck price though I'd like to see them make it in a Li-Ion battery pack version.
  • All you need is a $15.00 RV bypass kit. It's a ball valve and a 2' hose installed in the suction side of your RV pump. Google is your friend.
  • Why?? what is wrong with just using the regular water pump?? Does your RV have one??

  • Just an RV water pump...but you should use the one already there.
  • Get a little drill pump for $5.19 from Amazon or your local haardware store. Buy a couple of fittings to put 3/8" or 1/2" plastic tubing on both sides and you're all set to go.

  • I use the 12v water supply pump built into my water system. but you could rig one one real easy.
