I have a jensen wood boiler that I installed in a shed out side my house, I run 1" pex tubing under ground to the house, it runs up to the ceiling across the room to a water tank, down into the water tank through a bus heater core and back threw return line the same way to a tank about 12" above the stove, problem is it will not push the water threw the pipe, I hooked up a rv pump to it and that will pump the water around, but when I on hook it the bell& gossett L30 pump will not move the water around, the total pipe run there and back is around 100', what can I do thanks.
Jesus, call a tech. I hate these very wildly off topic posts by new people
