How a Bad Water Pressure Tank Can Cause Water Pressure Loss or Complete Water Supply Loss
If the building water supply stops and takes minutes to hours to recover,
you may have problem with the well flow rate. But the problem of lost water supply and pressure could be
more mechanical: a bad well pump.
The well pump, in turn, could have been damaged or hastened to the end of its
life by a bad water pressure tank which has caused well pump short-cycling. Short cycling of the pump motor can burn up
the pump relay control.
Water tank short cycling: A bad or defective water pressure tank which has lost its air charge or which cannot keep its air charge
will cause well pump short cycling - rapid turning on and off of the water pump. This frequent pump switching on and off
is hard on the pump (damages the pump) and also on the pump switches and controls (switch contacts can become burned).
Short cycling is especially risky with an older water pump, and might push it over the edge of failure.
When the water pump fails the building will simply lose water pressure (and water supply) completely (unless it by luck the building is served by an artesian well).
Old water pumps may stop when hot: A water pump might be at end of its life and about to burn up but still work after a cool-down cycle.
In other words when the pump has been working hard and the motor is hot the pump may stop running. Since the water pump may have been
overheated due to short cycling, the actual root cause of its stopping may be the water tank (loss of air or a bad pump control) not
the pump itself. After the pump has been off for a while it may magically start working again: some water
pumps have an internal thermal overload switch that shuts them off combined with an automatic thermal switch reset.
This is most likely to be found on water pumps that are inaccessible such as a submersible water pump.
In this case water pressure and supply will stop completely but will return after the pump cools down. But this failure is likely to be recurrent.

Water tank air bladder problems such as a burst bladder or one which has become collapsed and stuck to itself can also cause
water pump short cycling and the loss of water pressure or flow shown above. Less common in our experience but possible is water tank inlet
clogging due to a high level of sediment in the water supply, leading to similar symptoms.
More often water sediment clogs the sensor of
a water pressure regulator or it may clog a water filter, both of which lead to reduced water pressure and ultimately complete loss of water supply.
Our complete list of causes of loss of water pressure is discussed and water problems are diagnosed in detail at WATER PRESSURE LOSS DIAGNOSIS & REPAIR where we review
the all of the things that can cause loss of water pressure or loss of water entirely in a building.
