[QUOTE="Alchad, post: 7605207, member: 143348"] OK, before retiring I earnt my living as a chemical engineer for 25 years, so am pretty familiar with design of pipework systems. We have a system which pumps up to a tank/reservoir for a couple of hours a day. When it is pumping the pump has to overcome the head difference between the pump (static pressure difference) and dynamic pressure drop created by the flow. So yes when the pump is operating there will be the pressure drop you quote, and in actual fact it will be a lot more because I think the pipe is only 25mm. BUT when the tank is just sitting there with a few metres of water in it and feeding say the house when we flush the loo or a trough when the sheep have a drink, the flowback down the pipe will be very small and dynamic pressure drop will be very low. Perhaps we are misunderstanding each other? Alchad [/QUOTE]
