How can you check if the internal rubber diaphragm of an expansion vessel is broken?
Aquasky Pumplus pressure tank with membrane are pre-charged with nitrogen through an air valve. The butyl rubber diaphragm inside the vessel keeps the water separated from the air. Therefore, in case of malfunction, to check if the diaphragm of the vessel is broken, you must act on the internal mechanism of the air valve, pressing it with a tool such as a screwdriver, and checking what comes out. If water leaks, it means the diaphragm is broken and the water has completely filled the vessel. With the water pressure inside the water system, the water comes out from the air valve. Thus, we can see the diaphragm is broken. Please contact Aquasky service team to assist you.
