Geyser repairs

Most hot water problems come down to a handful of components. We test before we replace, so you are not paying for parts that were never the issue.

  • Elements and thermostats
  • Pressure control valves and vacuum breakers
  • Leaking connections, unions and flexible hoses
  • Drip trays, overflows and tray drainage
  • Thermal insulation and pipe lagging

Burst and leaking geysers

A burst geyser is an emergency. Close the geyser isolation valve if you can reach it safely, switch the geyser off at the distribution board, and call us.

We drain and remove the failed unit, check the tray and overflow that should have carried the water away, and quote on a replacement before installing.

Geyser replacement and new installation

We replace geysers in roof spaces, on roofs, in cupboards and outside on walls, and we install new geysers where a bathroom or extension is being added.

Installations are done to SANS requirements with the correct safety valves, drip tray and overflow so the installation passes inspection and protects the ceiling below.

  • All common brands and sizes
  • Roof, ceiling-space and wall-mounted installations
  • Correct valve set, tray and overflow every time
  • Certificate of compliance arranged where required

Pressure problems and geyser plumbing

Fluctuating hot water, banging pipes or water spitting from the overflow is usually a pressure control issue rather than the geyser itself. We check incoming pressure, the pressure control valve and the balance between hot and cold supply.

We also handle the pipework side: re-routing hot and cold lines, replacing corroded connections and tidying installations that were rushed.

Residential and commercial hot water

From single-geyser homes to complexes, guesthouses and small commercial buildings running multiple units, we service the whole installation and can advise on staged replacement of ageing geysers before they fail.

Geyser Repairs & Installation: common questions

How long does a geyser replacement take?
A straightforward replacement is usually completed in a few hours. Difficult roof access, corroded pipework or a change of geyser position adds time, and we tell you before we start.
My geyser is leaking through the ceiling. What should I do first?
Switch the geyser off at the distribution board and close the geyser isolation valve if it is safe to reach. That stops water feeding the leak. Then call us so we can get there and remove the unit.
Why does my geyser overflow drip constantly?
A steady drip is normal during heating, but constant running usually means a faulty pressure control valve or too much incoming pressure. Both are inexpensive to correct compared with the water they waste.
Do you supply the geyser or must I buy it?
We can supply and install, or install a unit you have already bought. Either way you get a quotation up front with no call out fee.
