• Shorten your shower. Each minute you add to your shower time uses about 12 litres of water. For a household of three that extra minute costs you about $90 a year in electricity.
  • To help keep track of time, try using a shower timer. Contact us and we'll send you one for free!*
  • Consider installing a low flow shower head. Their clever design gives you the feel of a normal shower but can significantly reduce the amount of water used.
  • Don't just watch the shower warming up! Use a bucket in the shower to catch water as it warms up. It's easy to carry out of the house so you can keep water hungry herbs happy in summer.

  • When running the bath put the plug in first and adjust the temperature as the tub fills.
  • Reduce the depth of your bath. The average amount of water used for a half full bath is 80 litres, compared to 140 litres for a full bath.
  • Baths typically use more water than a shower.  However, a 10 minute shower is equivalent to a bath so if you feel like a long soak, a bath is actually a better option. 
  • Use eco-friendly products and then you can reuse your bath water on your house plants or garden.


  • Turn off the tap when you are brushing your teeth.
  • Rinse your razor in a plugged sink, not running water.
  • Consider installing water aerators on all your bathroom taps.
  • Turn the taps off tightly and check all your taps for leaks.


  • Check your toilet cistern doesn't leak.  Toilet leaks are often silent.  A continuously running toilet can waste more than 700 litres of water a day and is not something you can ignore. 
  • Don't use your toilet as a rubbish bin. Only pees, poos and paper should be flushed, the rest should go in the bin.
  • Use the correct dual flush option (half-flush for liquid waste and a full-flush for solid waste).
  • Consider installing a toilet weight flush limiter if your toilet is pre-2005. This simple gadget gives you control of how much water is used each flush.
  • Stand a full 2 litre plastic soft drink bottle in your cistern to save water every time you flush. This can achieve savings of up to 5,000 litres per year.
  • When shopping for a new toilet, use the water efficiency labelling scheme (WELS) to help you choose. Just remember, the more stars on the WELS label, the more water efficient the toilet is.



Don’t delay, check your toilet today.

  1. Remove the toilet cistern lid
  2. Put a few drops of blue or green food colouring into the cistern
  3. Wait 15 minutes.  if the water in the bowl has changed colour, you have a leak
  4. Flush the coloured water away so it doesn't stain the toilet bowl
  5. A deteriorating washer in the inlet or flush valve is a common cause of water leaking into the toilet bowl.  Either call a registered plumber or if you feel confident, fix the leak yourself 



Article from Stuff

If your toilet's always a-going, it means the flush valve washer is worn out, or the ballcock washer (the thing that floats in the cistern) isn't shutting off properly.

Whether a homeowner can fix it, "depends on how handy they are."

"Flush valve washers are easy to fix, depending on the toilet," said Crump. "Normally you can remove the whole centre part of the system, that's where you find that washer. Over time they just perish and wear out, so you can replace that."

"The ballcock often a bit more complex, often you have to take the whole thing out. A lot of the more modern toilets, it's the same sort of system but they look a lot more complex. So to service them is probably a lot harder for a homeowner."



Plumbing advice 

'There are generally only two reasons why this is happening; either the flush valve is not doing it’s job properly and is letting water through, or if it is a more modern toilet cistern, the flush valve has a centre overflow and your inlet valve is not shutting off and is overflowing back into the bowl instead.

Again more often than not this can be repaired with a new washer kit with prices for flush valve washers ranging from $3.00 – $20.00 plus minimum charge for installation. Unless told otherwise by our client, when we are servicing a leaking toilet cistern we will always replace the washers in both the inlet valve and flush valves at the same time as we feel the small extra cost of doing this at one time will save you money in the long run.'
