Hi,

I'm planning to put up a water tank and I need sound advice from tank experts. So basically my questions are:

1. What height should the tower for the tank be? (or is it really necessary?).
2. Related to 1. Is it possible that i don't need to put up a tower at all if I buy and on-demand booster pump?
3. What is the ideal tank size for a household of 4 people, 2 bathrooms.
4. Where can i buy these things (tanks, pumps).
5. If I need a water tower, whats the most cost-effective way to build it? (steel bars or concrete)

Thanks in advance!
