The PC has the ability to repair a water pump at two points: the pump itself in Burham Springs and a section of broken hose inside the first level of the mines. This lowers the liquid level in the toxic caves. Repairing the pump lowers it significantly. Fixing the hose lowers it even more. After the pump is fixed, almost all of the water is gone except for the water covering the Agricola lab. Once the hose is fixed, the water covering the Agricola lab is also removed.
Frank LaFrancis told me that the water pump in Burham Springs used to pump water out of the lower caves. Since the impeller broke and the lower hose were damaged, it hasn't worked very well. If the pump were fixed, it would make exploration of the lower caves much safer.
Frank LaFrancis was pleased that I fixed the water pump and the lower hose. He gave me some items for my trouble and wished me well.
I fixed the impeller on the water pump, and it started running much better.
I fixed the hose for the water pump inside the mine. It should be able to actually carry water now.
