Who we are

Built for the dry days.

We plan, plumb and maintain the water systems that keep your home and garden running through every outage and restriction. Tanks, pumps and irrigation — specified properly and fitted cleanly, so they work the day we leave and long after.

You get a system designed for your property, installed by a team that cleans up after itself.

Good to know

Questions we hear.

How do I know what size backup tank I need?

We size the tank to your household water use and how long outages typically last in your area. Tell us how many people live in the home and your usual daily demand, and we will specify the right litre capacity.

Do you fit the tank and pump on the same visit?

Yes. The water backup system installation covers the tank, pump and all connecting pipework — fitted, tested and commissioned on site in a single session.

Can you design irrigation for an existing garden?

Absolutely. We walk the site with you, draw up a zoning plan based on your beds and lawn, and leave you with a full materials list — ready for us to install or for you to lay out yourself.

How often should a backup pump be serviced?

We recommend a service and flush once a year. We descale the pump, test the pressure switch and check the float switches so the system is ready the moment municipal water drops.

Do you work across all of Johannesburg?

Yes, we install and service across Johannesburg and surrounding areas. Send us your suburb and we will confirm we cover it.

Real reviews from real customers

The team from Ernest water backup systems was super friendly and made the whole installation process completely hassle-free. Our water pressure has never been better!

Naledi R.

We got fantastic value for money on our full setup, especially considering the high quality of the work. It’s such a relief to finally have a reliable setup in Johannesburg.

Zainab K.

They recently serviced our 5000L JoJo water backup tank with inlet filter, and the pump is running like brand new again. Excellent service all round.

Liam L.

Great service from start to finish. They designed a brilliant garden irrigation drip kit that has made keeping our lawn green so much easier during water cuts.
