Dude.. I'm not saying use the tinaco as your primary water source. Use it as a secondary source.
Where I live we have 11 apartments with a huge cistern (20K+).
We have 4 large interconnected tinacos on the roof.
When the electricity goes off, the tinacos supply water to all 11 apartments. When the electricity comes back, the pump fills them again.
That's why we always have water.
I don't have room on my roof for such tinacos because of how my house is built and the roof slopes.
So I won't be going that route after looking into it already. Yes , I could build platforms on the roof, plumb network of tinacos into my existing water lines in some way, etc if I really wanted to.
The rules in our housing project included a cistern and pump as a requirement for all houses. Mine currently is full. But of course that depends upon CORAAPLATA and their current 5 lbs of water pressure remaining on enough time. Soon, I will have a well as an alternate to fill the cistern.
So, my secondary source of water is my cistern. If I need to, I will reinstall a separate inverter system for the cistern pump which was
how my house was originally set up (30 plus years ago) and still had the inverter when I purchased it. But then we had 40 pounds of water pressure many years regardless of Edenada being off or on back then and I never needed to use the inverter so I removed it.. Now Edenorte is off mainly for maintenance which doesn't seem to ever make any difference, or accidents when cars snap poles off. Those accidents seem to be increasing exponentially in recent days, not sure I can do anything about that.. Let me think... nope...
Today the big problem is CORRAAPLATA and their extreme incompetence and corruption. I mentioned the comments on FB about requesting people to throw bags of fecal matter into their offices. In a month or two, I should have a new way to fill my cistern.
