How should the pump suction pipe be?

As we just mentioned, the pump suction pipe should be as short and straight as possible. If there are situations that require the suction pipe to be long, then pipe diameters can be increased to reduce friction losses. If the pump is going to transfer water to a place below, then the suction pipe must be in a position that rises continuously towards the pump. Thus, you ensure the evacuation of air that may occur in the pipeline. The suction pipe must be absolutely leakproof, therefore it must be carefully checked. If the pump is fed from a pump that is much higher than itself, then an isolation valve should be used in the suction pipe with its axis in the horizontal position. This valve should always be in the fully open position when the pump is running. Air must be prevented from entering the suction pipe, and besides, there must be a distance between the tank supply pipe and the suction pipe. The tank supply pipe should be further away from the suction pipe and be located below the water level. While increasing the pipe diameter in the suction line, eccentric reduction should be used (with the flat side of the reducer facing up). A straight pipe line ten times the pipe diameter should be used at the suction pipe pump inlet. (Pipe diameter*10= straight distance) Pump suction installation should be supported from the floor or ceiling in a way that does not put a load on the pump.
