Hello guys I inherited my home from my grandfather who built in back in the 40's. The well is run on a 1/2 horsepower pump its only a 1 or 1 1/2 inch pipe going into ground. all pipes in well were replaced 20 years ago.It also has the original tank also lol and over the last 5 years i have had to replace pump twice and pressure switch 4 or 5 times. The switch was plauged by fire ants for the first 3 but here lately it has been burning out the contacts. If any water is turned on pump starts pumping automatically no matter what pressure switch is adjusted too.The pump is still good going to go get another switch this morning should i be buying a nes tank as well?
