Finally added a "how does a concrete pump work?" page

Sorry it took so long, but I finally added a page for people who want to know "how does a concrete pump work?" - see it at www.reedpumps.com/howdoesaconcretepumpwork.htm . I've also got a lot of other good technical information, troubleshooting guides, - just about everything you need to know about concrete pumps here: www.reedpumps.com/concretepumps.htm

Thanks!
