[Big Bear]

We have a new 3155rl and where trying it out this last weekend. We had two RVs parked next to us and they showed us their fancy two way connector (from a large box store from the garden department) that they had made themselves and hooked up to the black water washout and the city water. My question is, is this an good idea and will it hurt anything? I really like the idea. It will save time and the convenience is great. Thanks and safe travels.
