Very disappointed with this product. The pump worked fine but not all parts were included in the kit as pictured in the ad. The faucet fitting was not included. 1 star

Easy to use once I figured it out. I tried for the longest time to try to winterize my camper with this thing. The antifreeze would not go in. Instead it would squirt out all over the place and make a big mess. I opened valves, closed other valves and still could not figure out why it would not work. Finally, someone suggested removing the water filter. It worked perfectly after that. It would have been nice if the instructions mentioned that if you have a water filter in your system, to remove it. 4 stars
