Experimenting the Cycle Stop Valve

I took the plunge and experiment with the CSV125-1 product from the USA to be used here in Malaysia.
My house water main is not able to satisfactorily supply my additional second water tank on the roof which is about 13-meter elevation (another 1 meter higher than the existing water tank ). So my second water tank is hardly full all the time since the incoming pressure was not that great. Thus when I decided to add a bulky sand filter, a booster pump is necessary.

Once set up, I found out that the pump pressure switch cycle on/off intermittently fast. A simple solution offered was to install another Electronic Pressure Switch Regulator. However, searching further I found this non-electronic Cycle Stop Valve product that claims to provide the solution to pressure switch problems and longer pump life.
I made the order via Amazon.

It was a simple ingenuity.
I delved further into plumbing works and made modifications to the current pump setup.

And from the online research, I was convinced that I need an external pressure tank.

The crude plumbing works after several modifications.

The entire setup once completed.
Now the pump pressure switch is working as expected, no fast intermittent on/off cycle. Household internal pipe is properly pressurized.
