JoJo tank installation

We supply and install JoJo and equivalent water tanks in the sizes that suit your property, from a single slimline tank against a boundary wall to multiple tanks linked together for larger households.

Every installation includes a level, properly prepared base, correct inlet and overflow arrangement, and neat pipework that is easy to isolate and maintain.

  • Site assessment and tank sizing advice
  • Base preparation and tank positioning
  • Municipal top-up and rainwater inlet options
  • Overflow, isolation valves and non-return protection

Water backup systems that switch over automatically

A backup system is more than a tank. We connect the tank into your household plumbing with a pump and control so that when municipal pressure drops the house draws from stored water without you touching a valve.

When supply returns, the tank refills automatically and the system goes back to municipal water.

Pumps, pressure and water supply during interruptions

The right pump matters. We match pump size and pressure to the number of bathrooms and the layout of the property so showers stay comfortable and geysers get the flow they need.

We also install pressure vessels where a system cycles too often, and fit filtration on the tank outlet where sediment is a concern.

  • Booster and pressure pump installation
  • Pressure tanks and automatic controllers
  • Pump housings and electrical connection coordination
  • Sediment filtration on tank outlets

Residential and commercial water storage

We install single-tank setups for townhouses and complexes, and multi-tank arrays for larger homes, guesthouses, offices and small commercial premises where a loss of water stops trading.

Existing tank not performing? We also repair and re-plumb older installations, replace failed pumps and correct badly connected systems.

JoJo Tanks & Water Backup Systems: common questions

What size JoJo tank do I need?
It depends on how many people live on the property and how long you want to run without municipal water. We look at your household use and layout during the free quotation and recommend a size rather than guessing.
Will the water pressure be the same as municipal water?
With a correctly sized pump and pressure setup, most homes do not notice a difference. Gravity-fed tanks without a pump give noticeably lower pressure, which is why we usually recommend a pump for anything more than emergency use.
Can the tank fill from my roof as well?
Yes. We can connect gutters and downpipes to the tank with a first-flush arrangement, either as the main supply for irrigation or as a top-up alongside municipal water.
Do you handle the plumbing connection into the house?
Yes. We do the full installation, including the changeover into your existing plumbing, isolation valves and non-return protection so stored water cannot flow back into the municipal line.
