Had the neighbors looking after our place for the month of July, they informed us that they left the sprinklers on for "at least a full 24 hours". Got the water bill, it wasn't pretty. Almost triple the water consumption of the previous month and we were only home for a few days. Damn.
That's what you get for not having an automated system!
I figured someone would reply with that My system is pretty simple though, turn on when needed, shut off when done. Can't find good help these days.
My dad's system had some moisture sensor and would only water when it "needed" it.
Funny enough, the neighbour who left the sprinklers on has the same system. It's obviously too complicated as he can't operate a simple system such as mine.
In all seriousness, I've seen his sprinklers running several times in the rain. Something's isn't "sensing" properly.
An automated system would be nice, I just can't justify the cost of the upgrade as we don't water much. I guess a couple more times with the sprinklers left on would be my justification. Now I gotta go look at sprinkler upgrades.
