heres how your pump works,basically its a cetrifical pump,it builds pressure by having a larger inlet than outlet. This builds pressure just like putting your finger over the end of a water hose. Since this restriction is built into the pump you can go to a larger size pipe. But if you go smaller you are simply decreasing the flow rate but increasing pressure. Going larger does just the opposite it increases flow,(up to pumps capacity of course) but it DECREASES pressure as long as pipe was flowing wide open.Just like putting the end of a water hose in the end of a two or three inch pipe,same amount of water goes out as in but less pressure until you restrict it back down and increase pressure again.What you have to watch out for though is building up so much head that pump simply cannot lift it to start.By going to a larger pipe you are creating back pressure simply from the weight of water making pressure on the outlet of pump. If I were going larger that far i would seriously consider putting a check valve in a few feet above pump.that would hold the head pressure until running pump built up enough to overcome it,and make your pump start easier.Head pressure is the weight of water above the water level in well.Since water seeks its own level so to speak head up to that point is simply neutral or equal.Water would stand that deep in your pipe regardless if pump is running or not.Above that point you have to lift it and thats the amount of head.Avoid getting so much head that your pump wont overcome it.if you do pump may run ,but since no water is going out,none comes in and it wont pump,and it wont build pressure.By putting check valves( or series of check valves) you can hold so much head pressure off pump.Then your head would be simply from water level to first check valve above the pump.Since freshwater is a pretty much standard weight,this figure is lots of times given in your pump specs as a gallon figure.By knowing this ,and the water capacity of your pipe,you can calculate where to set checks.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
