Not sure this belongs, but my most proud automation is an automatic water bowl for my dogs. It automatically drains, rinses, and fills 16 times per day so they always have fresh water. They deserve a better life than my lazy ass can give them.

    :O it's hooked to the tap and a drain I assume? How big is that?

    Correct! It connects to a sink drain the same way a dishwasher does. It is actually a bathroom sink, the kind that sits on top of the counter. We have had three Great Danes at one time so trying to keep up with a clean water dish was really impossible. We no longer have large dogs but the desire to keep them in clean water persists.

    What a clever idea! Is the dirty water drained from the bottom of the bowl or is it pumped out?

    Pumped from the bottom. The basin sits on a raised box that holds the internals, including a pump for draining and a water valve for filling. Basically it uses a timer that commands the pump and a sump circuit for the fill valve detecting high, low, and overflow conditions.

    The pump runs for three minutes every hour for sixteen hours between 0600 and 2200. The three minutes is enough to drain the entire thing with enough time for the clean fill water to rinse the basin and be drained away before stopping the pump and letting the fill top it off with clean water.
