What does diaphragm hydrophore mean in practice?
A flexible membrane separates water from gas, so the air bag does not dissolve directly in the stored water.
When does it matter?
A rupture of the diaphragm causes flooding of the gas side and frequent activation of the pump, which will not be corrected by adding air.
Which solutions are related to it?
The air valve and pre-pressure are checked after draining the water, and the damaged membrane or tank is replaced.
