Folks, Been watching the thread and wanted to chime in a little as Mr. Huggins, PE has done.
Any 220V pump and any tank that will hold water are an acceptable supplies in areas served by well water. And when sizing the tank, you may use the water supply's refill rate to eliminate some of the gallons required to be stored. So on a home with a well pump (that probably already has it's own pump and pressure tank), you can branch off of that supply and fill a tank. That tank can be sized like so: Demand gpm X 10 minutes = Total Water (in gallons) Home water Supply gpm X 10 minutes = Total Refill (in gallons) Total Water MINUS Total Refill = Tank Size Two sprinklers (YES! ONLY CALC 2 IN THE BASEMENT) x 10 minutes usually equals less than 300 gallons total. Subtract 100 gallons or so for refill and you only need a 200 gallon tank. A 6ft tall, 30" diameter tank (fits through a 32" door), will suffice (+/- 220gallons). A 2HP pump can handle this (up to 45 psi). See SPD Pumps for some really good charts and products.http://www.spdinc.com/products/residential.html (Or call and talk to Dave and tell him I said, "YO!") This is a very inexpensive solution for a rural home. It should be recognized that the above is my opinion as a member of the NFPA, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the the NFPA, nor any of their technical committees.
