So a few days back, the water pump burned up so we had no water for two days. During that time, I turned off the thermal tank because I had no clue how much water it had and pouring cold water into a hot and dry thermal tank is dangerous. We changed the pump, cold water started flowing again, the tank filled up and heated up. I opened the hot water faucet but no water came out. Not even cold. I left every hot water faucet open during the night in case there was an air bubble. Today, not a drop came out. I opened the drainage valve on the tank and it indeed has water. Any ideas?
Note: I live in the middle of nowhere which is why I have a water pump 60m underground and a thermal tank.
