How to install a pressure tank?

[oj88]

Alternatively you may use a Cistern tank instead of an overhead tank, it could work like a grease trap-this time the sediments remains on the bottom.

A regular Jetmatic with pressure tank has built-in pressure switch that maintains the output pressure in the storage, motor will run based on the pressure range that is set on the sensor. Another intake sensor can be installed to control/ protect the pump motor from running if there is no/or low water supply coming from the mains/tank.

Something is wrong with the diagram.
The water supply going to the pressure tank should come from the side of the storage tank. The side elevation nozzle must be higher (around 4-8 inches) against the bottom of the storage tank to prevent sediment from being drawn in, if any is present. Water agitation from supply main shall be put into consideration during filling time. The bottom connection or lowest point nozzle can now be used as the drain and cleaning port.

The drawing is just for visualization. In reality, the bottom pipe (outlet) actually punches through about 2-3 inches higher than the bottom of the tank. There's also a separate drain pipe.

We were planning to use a traditional pressure tank (stainless, non-bladder) but I sort of stumbled upon the inverter pumps. On paper, I am liking the features: Quiet operation, low power consumption, WiFi control, etc. Not sure if all that is worth it in the long run, especially on reliability.
