Questions
Frequently asked
What size tank do I need?
It depends on how many people live with you and how carefully you use water during an outage. At 100 L per person a day, a family of four gets about 5½ days from 2 500 L and about 11 days from 5 000 L. Our water calculator works it out for your home.
Can I drink rainwater from the tank?
Not untreated. Roofs collect dust, bird droppings and leaves. With filtration and UV the risk drops a lot, but we only call water drinkable after a lab test against SANS 241. For drinking, we recommend reverse osmosis at the kitchen tap.
Will it work during load-shedding?
A pump needs power. On the Smart and Premium packages we connect the pump to your inverter or a dedicated battery. On Essential Backup this is an add-on.
Do I need approval from my estate or HOA?
Usually yes. Most estates control where tanks go, their colour and whether they can be seen from the street. We prepare a drawing and photos for your HOA and wait for written approval before installing.
Does the water in the tank go stale?
Our mains-fed systems draw through the tank, so the water is used and replaced all the time. We use tanks with a black food-grade lining and place them out of direct sun where possible to prevent algae.
How long does an installation take?
Essential Backup is normally one day. Smart and Premium systems take one to three days, depending on tanks, electrical work and treatment.
Why not just buy a tank-and-pump combo from a hardware store?
You can, but it still has to be sized, put on a base that can carry over five tonnes, connected with automatic changeover and backflow protection, and signed off by a registered plumber. A badly installed system can damage property, and insurers can reject claims for uncertified work.
Not sure which package fits?
Answer a few questions and we'll recommend a tank size and package.
