I was wondering if anyone had experience or heard of the easiest way to use sprinkler system to refill a small pond up to a needed level every once in a while. Please suggest something if you can. The only easiest thing I can come up with is to have a separate zone that would be programmed for a certain amount of time every day. The downside of this that it'll always have to be maintained and program adjusted in order not to overfill or underfill. I wonder if anyone have better solution. Thank you in advance.
