Thanks all for great advices, I contacted the manufacturer and the problem is that factory connecting kit for tanks is rated for flow of only 20 l/h, our contractor had installed heating oil tanks and never checked the ratings. Obviously this configuration can not withstand flow of 200 plus l/h...

Have you seen the Schütz drawings? It is factory kit for connecting multiple tanks, but there is no return line from generator to tanks as we have. What do you thik about my idea to put separate piping and connecting the tanks so they will level naturaly also than I can remove three inlet and...

After long power outage of 24h we noticed that tank levels are...
