Damage to problems like this before suppose from normal, most often on Foot valve at the bottom of the suction pipe is leaking. Rubber foot could leak due to worn valve or it could be due to hampered sand.
Try opening and closing of provocation on the blog to see if the water pump is empty of water. If the foot is definitely empty klepnya leaking, fill with water to the brim and turn on the water pump, wait a while, the water will flow again. If after the water could go up but then if it was shut down a few times like that again means that should do the replacement foot klep.Akan but if it's fluid means Footklep hampered only sand and sand when in turn come up to the top.
