Runnin on Empty
New Member
This is going to be a little long but I need help. I am also a new member. I have a 2000 SB 400. I have an issue with my fresh water. When I commissioned the boat this spring I filled the fresh water tank. Soon after turning on the pumps the tank drained. I closed all open bibs etc and all the water is draining not pumping out via the last small drain hole on the starboard side. The pump seems to start at random and then empty the tank. It is not going into the bilge and I cannot find where the leak is. The pumps will pressurize as normal and then sometime later maybe an hour turn on and pump the tank dry. Any ideas?
