The pump impeller can be accessed by using an adjustable slip-nut wrench to turn the disk mount assembly counterclockwise. Once the disk mount assembly is removed, the impeller can be removed.
Very often the disk mount is hard to unscrew because of minerals build up in the tread. In such situation it has to be broken in pieces. You can use a chisel or a flat blade screwdriver. Be careful not to damage the pump body.
