Oh cool. Ok. My wife just used a program to size the pics. I'll find out what size. Btw, thank you so much for responding as quick as you have. I really appreciate it.
As for the problem solving, here is what I've learned. We decided not to install the tank, but primed the pump, which was a total a** freezing experience. What I have to do is connect a hose from my son in law's house next door, to a faucet right at the bunker that goes down to a Tee at the valve that feeds the house. I then open the source to force water into the house pipes. Then close the valve and force water into the pipe between the pump and the tank, which I do by opening a little bleed in a fitting at the pump. As soon as water comes out I shut off the source next door and open the valve to the house. Total PITA. Especially in this weather.
Ok, heres the deal. Our water has so much crap in it, I'm beginning to believe it might be buildup in the tank and maybe some valves instead of waterlogging. Today we opened the drain valve for few minutes, but it was draining so slow, this is why we decided to wait to change it out. Tomorrow, I'll drill a hole in the tank to allow air to enter. However, once we got the system primed, my wife tried to fill some drinking water jugs with filters. Holy moly. The first one filled with dirty brown water. The second one was less but still brown. Never had this happen until we tried to drain the tank. Another thing, there is a shutoff valve under the house, that is wrapped with insulation. Two years ago, in the middle of winter, that valve, which is plastic, fractured because of freezing. It got down to -10 during the Arctic Vortex that year . Had to change it out laying in the snow. No fun. But because of finances, I used a plastic valve again. It might be leaking again. Tomorrow, I'll drag myself under the house and check for leaks. Until then, wife is happy. Got water. Toilets cleaned, and dishes done. That's all that matters tonight. Thanks again. I'll post any new things I find tomorrow.
