I have 2 water tanks installed in my 3 story building. 1st one is on top of the 3rd floor, the other one is on top of 2nd. The pump is installed at Ground Floor. Now I made one outlet at 800 lts of 3rd Floor tank of 1000 lts capacity as inlet for 2nd floor tank. However the pressure was very low and before 2nd floor tank filling, 3rd floor tank was getting overflowed. How to address this problem

If the cold water pressure is good, then you are right about the shower head not being the problem.
Check the hot water shut off valve feeding the tub to assure it is opened fully.
Also if you have good hot water pressure at the vanity and are sure shut off valve is fully open, the problem may be in the mixing valve that feeds the shower head. It's not uncommon for deposits to form over a number of years in this valve and restrict flow, especially on the hot side. Could also be a broken or stuck washer in the mixer. You can shut off the water to the valve, hot and cold, remove and inspect the cartridge from the front. Remove the handle(s), the bezel trim and the valve cartridge should come out with a wrench. If any of the internal parts look suspect, take it to your hardware store and they can help you select new soft parts to rebuild it. Replace it in opposite order that you disassembled it, and don't forget to put some plumbers putty under the top and sides (not very bottom) of the bezel, so water won't leak in behind it and down your wall.
Good luck.
To set this up with a submersible pump, you need to have:
- Submersible pump: at bottom of cistern. You'll want to clean any sediment from the tank before installing, as if the intake is directly on the bottom then it will suck it up and could possibly clog the pump or your plumbing fixtures.
- Control box: needed only if you have a 3-wire pump; 2-wire pumps don't need this.
- Normally open float switch: located at bottom of tank, set so that when it's down, it shuts off, and wired in series with the power to the control box so it prevents the pump from turning on when the tank is empty.
- Pressure tank system: Pressure tank, pressure switch, gauge, and sed valve (not shown). This is just the typical setup to use with a pump
- Shut-off valve to the house: again, just typical part to make servicing easier
Optionally, you can install a second normally closed float switch (set to turn on when facing down) at a slightly higher level than the other one, and wired to an indicator light in the bathroom or wherever. This will alert you when the tank is almost empty.

The solution is to mount the tanks so the filled surface of each tank is or will be at the same level.
That means some tanks will be mounted on supports at different heights to others.
if These tanks are to stay on separate floors, then the second floor tank will need a one way connection to the outlet to stop the top tank filling it.
Both tanks need a fill control valve.
