First post on this site. Looks like a great forum!
High current on water pumps is usually due to how much water you are trying to pump (move). Blockages or valves restricting the suction end of the pump will decrease current, not increase current.
Go to the suction end or valve in that pipe. Temporarilly block the suction with a current clamp on motor lead. The current should drop to about 1/3 of FLA. If there is a valve on the suction side of the pump close it slowly until the desired current is obtained.
Many people have the idea if you block the suction side of a pump or fan the current will rise. The truth is the exact opposite. The pump or fan motor is doing no work unless it is moving water or air.
If the current does not fall way down after blocking the suction end, then I would consider all the suggestions mentioned above.
If this pump has been serviced in the recent past, check the impellar. It may be the wrong one (pitch).
