Hi Bill,
I do not know if it is better, but the least expensive replacement I found was the flexible water fill hose used in many trailers and fifth wheels. They have a gravity feed water fill the same diameter as our drain line under the kitchen sink. It looked identical to the original. Most trailer supply stores carry it on a roll, and sell it by the foot. I replaced mine in Las Vegas about 3 years ago, and have had no problems since.
