Just installed this winterizing kit on my 2018 Winnebago and wow - that 59" siphon hose is a GAME CHANGER! No more awkwardly stretching a short hose while antifreeze spills everywhere.

The brass components feel solid AF compared to my old plastic valve that cracked last winter. Though fair warning - the teflon tape included is basically dental floss thickness. I used my own heavy-duty tape for peace of mind.

Water flow is indeed unrestricted (tested by accidentally leaving it on full blast - whoops). The valve switches between modes smoother than my grandpa's old whiskey pour.

Only gripe? That "brass barb adapter" looks suspiciously like something from my kid's erector set. Still held tight though!

Final verdict: At this price point, it's way better than fighting with those cheapo plastic kits. My plumbing hasn't frozen yet and we've hit -15°F. Would winterize again!
