If you use a wire (small cable), you can cut through pvc pipe without cutting you interior wires. Cable ends with each end in each hand, pulling alternating like your cutting through a tree limb. Works really good. Just another way to do it.
Good sytem , why wooden box coz it will rot two years down the line you will have to build it over and over again , I think brick linning was a more suitable option
Easy to pull up pump, cheaper than hiring a drilling company..... Before starting a project you already know the spring yield...... I can rate it 99% over borehall, the 1%is the safety of the pump , it is prone to theft compared to deep well pump....
