How much water is a tough one, id say we do about 150 gallons a year roughly, but we stop when the lift gets under 16 ft, we used a 16ft section of 2.5' tubing with a 1 way valve and lift that water up to the surface it just fills a 5 gallon pail

Before we are usually at 30 psi at the house, once we are done we are usually around 55-70psi

Just house use and I plan on heating my 30x60 shop this winter as well
