Bought a 20 acre farm. Built the garage first, 90% complete. Plan to build a barn and 2300 sq ft home, all separate buildings. The plan is to make the garage the center point of the utilities, gas, electric, cable and water. At the point to install the well water into the garage. My question is what would be the recommended pressure tank size to put in the garage which would feed the garage then send water to the house. The house is to be 50 feet corner to corner from the garage. Also, what would be the estimated water line size from the garage to the house?
Would it be helpful to install a second pressure tank in the house with a check valve between the two?
Any recommendation or advice would be greatly appreciated!
Big pressure tanks are no longer the preferred method of controlling pumps. Constant pressure systems have become the most popular way to control pumps. Variable Speed Pumps or VFD's have been redesigned 6 or 7 times in the last 20 years, because they still can't get all the problems solved. However, the Cycle Stop Valve is very dependable and therefore has remained unchanged, and has been replacing VFD and large pressure tanks for more than 15 years. Big pressure tanks only slow down the cycling, while a CSV eliminates cycling. The CSV delivers "constant pressure" as compared to constantly varying pressure as when controlled with a big pressure tank. Since the CSV eliminates cycling, you can use a very small pressure tank. The system pictured below works on pumps up to 25 GPM. You can install this in the garage, and tee water lines to the house, barn, irrigation, or wherever else you need water. The CSV system not only delivers constant pressure but, cost less than big tanks or VFD's, makes the pump system last longer, and saves considerable space in construction and for heating purposes. Big tanks are a thing of the past.
The size of the pipe line depends on how many GPM your pump puts out and how far the line is going. 1.25" or 1.5" lines are fairly common for house well size pumps.
