I am planning to buy an apartment, while enquiring about it, the marketing manager said the below points about the water facility.

  1. High Pressure water Motor will be used to suck the water from bore-well.
  2. The High Pressure water Motor will be running for 24/7
  3. There will be an over tank in all towers and it will be used for emergency purpose only. i.e if I open the tap, I will be getting water thru the motor which is running 24/7. If the motor is not running I will be getting from over tank.

My Questions:

  1. Does it make any sense in terms of current (power) utilization? As we have already power problems, current cut very often, this high pressure water motor would be a current overhead right?
  2. What is the need of running the water motor continuously?
  3. This facility will hit the maintenance cost.

Though I asked these questions to that marketing manager, I am not satisfied with his replies. So can anyone please give your inputs on my queries?

Are you sure he meant 'spinning 24/7' and not just 'powered on 24/7, but controlled via pressure switch so it intermittently turns on and off as needed to keep the system pressurized'? –  gregmac Jun 23 at 13:48
    
I'm not sure if you're considering buying the entire building or just an apartment; but if you're buying the building it would also be worthwhile to look into how this system operates. Ideally the apartments draw from the tank, which is in turn kept full (using float switches) by the well pump. This keeps the water in the tank 'fresh', allows emergency use with no human intervention, and gives you a buffer if demand temporarily overpasses supply. You'd also ideally have a continuous level monitor or at least a low-level alarm to alert you before the tank runs out. –  gregmac Jun 23 at 13:51
    
Hire a competent plumber (and not the one the facility uses) to evaluate the system for you. –  longneck Jun 23 at 14:01
