Many smaller motor-homes have a water-tank filler inlet that is separate from the city water connection. Filling the tank often requires patience while holding the hose in place and adjusting the water flow to prevent the water from backing up. I bought a length of ½-inch clear plastic tubing and a female brass garden hose fitting plus a small hose clamp. Now I can attach the hose and filter to this adapter and slide the tube into the filler opening far enough to hold it in place. The tube is also small enough to allow air to escape while the tank fills.
