Boiler has no pressure - What do I do? - Mr Central

These would include as mentioned water loss or a leak meaning that the pressure would drop and in most cases the boiler would not fire up. If you have been away for a long period or the property has been vacant for some time then be really careful as it is often the case that the water would be very cold so indicating a low pressure but

Consequently, there must be a greater pressure drop between boiler number 4 and point A than boiler number 3 and point B, whilst the difference in these two pressure drops takes place between A and B. Flow depends on pressure drop, it follows then, that boiler number 4 will discharge more steam into the common header than boiler number 3.

Controlling TDS in the Boiler Water | Spirax Sarco

The water being drained from the boiler is at saturation temperature, and there is a drop in pressure over the orifice almost equal to the whole boiler pressure. This means that a substantial proportion of the water will flash to steam, increasing its volume by a factor of over 1 000.
