Wen, …. You make a good point about the sensor knowing the difference between branch and person, and it would be somewhat difficult explaining it to the pump. But, I do feel there’s a significant trade off here. There may be an “
inconvenience” of the pump stopping because of a branch, and having to remove it from the pool, …. But on the other side of the coin, I don’t think it would be an inconvenience having to pull someone out of the pool after being so exhausted from trying to escape a Suction Monster (suction pump).
You also make a excellent point about the equipment being turned off when not in use, …. But I believe in Murphy’s Law. If someone will forget to do so, … they will (
unless some sort of timer could be installed).
It’s in a kid’s nature to sit in a pool and play with the suction drain (I know, cuzz I did it – duh me
). If their lucky enough to get stuck with someone around, then they have a 50/50 chance of getting rescued (will they or will they not be seen in time?). If their unfortunate, and get stuck with no one around, then their screwed (unless they can work their way loose).
So, to me, it’s well worth the pump stopping and not knowing the difference between branch and person. It’s a lot more expensive having to bury someone than to replace a pump after being burnt out. Any hoot, that’s my 2 cent opinion on the matter.
BTW – How are things in Sac / Elk Grove ? I use to live in Elk Grove near Laguna Blvd. Was back there about six months ago, …. It’s really growing.
