OT reminiscences of my dad--was: Multiple pumps for failure
i keep thinking that my dad would have loved computers. when i was a kid we
had fancy radios, transistor radios, a shortwave radio, a movie camera, an early hand-held calculator, the first TV on our block with a 100 ft tall antenna, and a CDR rotor to turn it. our car had every gadget known to detroit on it. yes, he would have loved home computers. mad -- You don't stop laughing because you grow old, you grow old because you stop laughing. From: "Anne Lurie" Organization: Road Runner - NC Newsgroups: rec.ponds Date: Tue, 26 Aug 2003 23:25:22 GMT Subject: Multiple pumps for failure protection? Not much of a comment, except to say: Oh, man, how my father would have loved newsgroups with questions like this, sigh...... He was an engineer, we had a house on Lake Erie, and a cottage on Georgian Bay........ he used to get the monthly(?) reports from the Army Corps of Engineers about water levels on the Great Lakes. And, I swear, only my dad could get excited when he talked about "acre feet" (the amount of water necessary to cover one acre with one foot of water). Through in a question about pumps in parallel, and he would have been in his element, sliderule & all! [I realize this post was of no help whatsoever to Scott, who asked the question, but the memories that the question evoked are priceless.] And then's the question that occurred to me when I read an earlier thread (very embarrassing not to know the answer, as I'm sure I should know it): "Does a pump have to work harder to move water that's 6 feet under the surface than water that's 2 feet under the surface"? Anne Lurie Raleigh, NC "Scott Evans" wrote in message ... In a recent posting here, someone had lost their pump, and was wondering what needed to be done to keep their fish safe until a replacement could be found/installed. That got me thinking (never a good thing, but I digress) a bit about how to minimize the short-term impact of a pump failure. Going under the assumption that it takes a certain amount of power to pump a given quantity of water, would it make more sense to have multiple smaller pumps hooked up in parallel (with appropriate back-flow check valves) rather than a single large pump? It shouldn't take any more power to pump the water; the only additional cost would be the initial plumbing and pump costs. It might be a worthwhile tradeoff for peace-of-mind to put out a little more money upfront to make sure that a pump failure won't take down a whole pond ecosystem. Comments?

Kept him very young.
