Water tanks.., choose what kind of material ? Plastic,Stainless or Concrete?

Make sure that if you do built a watertower that you put it high enough so you get enough pressure. Every 10meter equals 1bar of pressure. If your showerhead is at 2 meter high, and your tower 10 meter high, that only leaves an 8 meter differnece or 0.8bar water pressure.

How much water pressure does a gas water heater system need to switch on?

I re-read it and re-read it again...
I understand what you're saying, I just don't agree...sorry.

and I personally, see more negatives then positives.
but I wish all the best to people that do decide on a watertower.
