I have an old hand pounded 2" well in the basement (its no longer used for the main water supply of the house), Is their any idea's or ways anyone can think of to try to increase its ability for the purposes of a lawn sprinkler system? I assume its original to the house (year built is 1961), it produces water fine now and i have an updated electric pump and holding tank hooked up to it (home depot stuff, but the best home depot had!). Id does not seem to push more then 2 or 3 of the PGP sprinkler heads at a time now.... but i want it to look like Fenway Park

is their any methods to get more water flow without sinking a new well?
P.S. I do notice some orangeish discoloration of the water after its not used for a long period of time? also... is their any methods to quite this friggin' pump when it clicks on (I put a thick rubber mat under it which helped slightly)
I will post some pics as soon as i can.
