Valves and lake water.

I have been irrigating my lawn with lake water for a couple of years. I just ran a main line and used effluent sprinklers to see how it works. Works well so I'm putting in valves, controller and wire. Is there one valve better than others for lake water? Pretty clean lake but at times get a little algae or sand. Thanks

You might consider going "all out" and skipping standard irrigation diaphragm valves in favor of motorized ball valves, if your sprinklers can run on effluent water.

The best irrigation valve for water with algae will be the Rainbird PESB "scrubber" valves which are quite expensive, as might be any top-of-the-line product.

Another approach to pond water supplies is to strain and filter the water before it can enter the system, which has the advantage of letting you use standard valves and heads, but algae buildup on filter screens would have to be dealt with.
