I wonder if the purpose of the "overflow" pipes is to let air out of the tank as it fills with water?
When I'm topping up the tank with a watering can if I'm on site and don't want to move, I have to pour water in fairly slowly or I get an airlock and it gurgles and spits water out of the filling hole.
