Mar 12, 2014 · If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking. When the water temperature in the boiler becomes too high, it increases the water pressure throughout the system. This will cause breaks to begin occurring at valves and connectors.Get Price
