Well, I'm not real proud of it, but we've used pools as suction twice. Only other option was donating a tank to a for-profit hotel.
Cautions include installing oversize suction lines, like two 8" for a 500 GPM pump, with inlets at least 6' apart. Tell your pump guy yso he can nickel plate the impeller and something with lantern rings (Tom FGOL knows more about pumps than I ever will). On the last one we tried to rig up something that would function as an intermediate chamber and put a vortex plate on it, but it got WAY too cumbersome. Instead, the aforementioned twin 8" feeds and lots of water in the pool worked- the insurance co's field engineer witnessed the test, and was fine with no sign of vortex, accepted albeit not something you want to do. And this was before (or why) I was on #22 :) Glc Certainly nothing I'd suggest being done, and it's after 5 on Fri so I'm not touching the effects on pipe. Time for top-down drive home and stress management intake. A great weekend to all. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jim Kettler Sent: Friday, July 06, 2007 2:15 PM To: [email protected] Subject: RE: pool as water source We've only used pools as static water supplies. Regarding the issue on drawing suction while someone is in the pool - would it be possible to devise a preaction evacuation type alarm (something similar to a carbon dioxide fire system) to sound prior to the pump firing up? I see a potential issue with the delay in activating the fire pump though. Had one a few years ago where the building owner pondered using their wine storage tanks in lieu of water.
