Works as intended with no issues. We were able to winterize our RV in a matter of minutes and this way is far less expensive and messy than using antifreeze.
Nice quality. Helped me to gently glow out the water lines on the camper before winter.
Took WAY longer to read the instructions than to actually blow out the lines. Next year should be even better now that I know how to do it, and I won't have to waste a lot of water rinsing out the RV antifreeze in the fresh water tank!
Saved a lot of time and expense
