IIRC, your new on the place. You will need to check your static water level. You'll need string, a sinker and a bobber. ( small on both )You'll have to drop it until it hits water and then determine where your actual water level is. Its quite possible that it's far less than the stated well depth. The pump I linked is designed to go along side of what's in place. I have it just as security blanket in case there is more then a temporary outage.And my two wells are approx 191'. Well, now what?
