Let me start by saying this adapter kit *does* work—just not flawlessly. The first time I used it to winterize my camper, I was thrilled at how quickly it got the job done. No more messy funnels or frantic pumping! The gravity-fed system is genius when it works right.
But here’s the catch: getting a leak-proof seal on the antifreeze bottle is like playing musical chairs with a greased pig. I lost half a gallon of pink juice down my sleeves before realizing it needed a hose clamp (not included, seriously?). Once I MacGyver’d that fix with zip ties, though? Smooth sailing.
The PVC hose feels sturdy—no kinks even in freezing temps—but that chunky bottle adapter is awkward. Pro tip: Run hot water over it first to soften the material for a tighter fit. And yes, you *will* need to vent the bottle unless you enjoy watching your antifreeze defy gravity like a confused lava lamp.
For $20, I expected less DIY troubleshooting. Still beats paying a mechanic $100 to winterize my RV—just keep towels handy for the learning curve.
