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 in the water lines. Because this is so quick and easy, we can still take the RV out for winter camping, use everything as usual, and just winterize again on our way out of the campground. We live in central Indiana, so we see plenty of freezing temps over winter and have never had any issues using this method.
