Another miserable day at the cottage. I spent another 5hrs playing with the pump. Where my two lines come up from the well i have two 90's. From there i had two black pipes going to the pump. I changed those two lines today to clear pipe so i couls see what was going on. When the water pressure almost reaches it's cut off point i see air in both lines. Could it be the jet and foot valve??? The one that i put on at the end of the summer wasn't new ( so i was informed by the guy today who gave it to me). I cant see me losing the water that quick when it's just from flushing a toilet ????
