I have a Drip Irrigation Multi-Port Emitter on a grouping of patio pots. I had an empty slot and figured I could use it to fill up a bird bath. Works like a charm except a couple hours later the water has all been siphoned out and its almost empty. I used a standard 2gph dripper. Is there a way or head that I can install that will not siphon? There's no way really to have the dripper fill the bath and not be down in the water.

Thanks in advance
