[QUOTE="Exfarmer, post: 7933111, member: 1951"] Flow is a combination of pressure, pipesize, and demand. As the When there is no demand the pressure across the pipe is constant. To get flow, you need pressure. As the flow increases the drag from the pipe increases dropping the pressure at the delivery end. So your pipe is either too small or the pressure at the source is too small. But first you must investigate the pressure at the source. If it comes from a large main even if the pressure is low you will still get a good flow. Then you need to decide how much water you need to your meadow. You then have three options, if pressure is low then you need a booster pump. You can change the pipe or possibly put a larger tank in the field so the water can run longer to fill it and supply your stock. There are on line calculators but if you post your estimated needs then some one here can probably work out your best options. One thing I would not do is buy a cheap booster pump as they can have a short life A good booster will be fully automatic but must be protected from frost of course. [/QUOTE]
