Plumbing Tips

Mr. H2O, your local experts for all your plumbing needs, offer these tips and hints for around the home:

How to Prevent Drain Blockage in the First Place?

altThe best strategy of all?  Preventing clogged or crack drains before they ever happen, and here a just of few of the ways to do that:

  1. Avoid planting trees and shrubs near your sewer line;
  2. Every now and then, pour an environmentally friendly root killer down your drain to kill existing roots, prevent new growth…and all without damaging your trees or shrubs;
  3. Pour bacon and other kinds of grease into a coffee can or similar container to dispose of later;
  4. If you do pour grease down your drain, pour lots of cold water on top of it… cold water helps to dissolve the grease, while hot water ultimately will help the grease build up.

For help with clogged drains or any related problems, contact Mr. H2O Plumbing & Electrical today, and consider the job done!

change a washer

altThere are several steps to fixing a dripping tap.

  1. Shut off the water supply and carefully remove the tap using a cloth-covered wrench/spanner to avoid scratching the chrome.
  2. Using a reseating tool, grind the tap seat till it is clean and smooth.
  3. Turn the water back on, briefly, to flush out any filings from the grinding. For this step, reinsert the spindle of the tap without a washer
  4. Next you need to service the spindle. It comes in two parts. Using your hands twist the central section out to separate the spindle into its two parts. Remove the black rubber O-ring. Using paper, clean the spindle and then put in a new O-ring. (Some spindles have two O-rings.) Grease the spindle with a generous dollop of tap grease
  5. Put the spindle back in (make sure the hot and cold buttons are on the correct taps), replace the washer on the tap body and turn the water supply back on. Test the tap. If you’re satisfied with your job, it’s now time to clean up. Use paper to clean up the grease.


altTo follow these instructions you need to know the parts of the toilet. The cistern is the part of the toilet that holds the water before you flush. It has an inlet valve and an outlet valve. The inlet valve allows water to flow into the cistern and the outlet valve is connected to the button that you push to flush the toilet to allow the water to flow into the bowl.

Water keeps running

If water keeps running into your cistern, chances are you have a faulty inlet valve. You’ll need to shut off the water at the isolating point below the toilet. Disconnect the water supply from the base of the inlet valve. Replace the valve. Reconnect the water supply.


Water dripping on the floor

If you have this problem, you might have a worn out flush cone or seals that need replacing. Mr. H2O can diagnose and fix the problem call 1300 095 212 or call your local number.

Flush button not working

If the flush button isn’t working you have a faulty outlet valve. There are many types of outlet valve. The best to use is one that has a central overflow into the bowl. Be careful trying to get the button off, you don’t want to break the cistern.

Some simple rules when repairing toilets

  1. Check the cistern for cracks. If the cistern is cracked it needs to be replaced. Cracked porcelain or plastic is very sharp and can be very dangerous.
  2. All new toilets must be dual flush.
  3. Always choose parts that are suitable for the brand of toilet you are servicing. Parts are not interchangeable. 



Saving water is good for the environment and for the household budget. Here are some simple suggestions for how you can save water around the home.

  1. Check for, and repair, any leaking taps, pipes and hoses. A single leaking tap can waste more than 2000 litres a month.
  2. Turn taps off lightly and replace the washers as soon as they begin to leak.
  3. Install water-efficient taps and showerheads, or tap aerators.
  4. Turn off the tap when you brush your teeth.
  5. Choose appliances such as dishwashers and washing machines that use less water, and only wash when you have a full load.
  6. Put the plug in the sink when you wash your hands, rather than leaving the tap running.
  7. Keep a jug of cold water in the fridge, rather than running the tap till the water is cool.
  8. Fill the sink to wash fruit and vegies, rather than leaving the tap running.
  9. Put the plug in the sink when you rinse your dishes.
  10. Instead of boiling vegetables, cook them in a microwave or steamer.



If you’re seeing rust in your hot water your tank’s sacrificial anode may have corroded away and your tank is starting to rust away.

A sacrificial anode is a metal rod that is placed in your hot water tank to prevent the tank from rusting. The anode creates a galvanic cell where the metal of the anode (usually magnesium or zinc) corrodes more quickly than the steel of the tank. When the anode has been eaten away the tank will rust quickly. You should check the anode periodically – do it on the same date each year to make it easy to remember! Replacing a worn anode will extend the life of your tank.

Regularly checking and replacing your hot water tank’s sacrificial anode will double or even triple the life of your tank, AND prevent costly damage from a ruptured tank.

The anode is typically screwed into the top of the tank or it may be built into a special fitting. Mr. H2O can check your sacrificial anode and put in a new one if needed.

Why Replace the Anode?


 Please note: A resident can change his or her own tap washers and undertake other plumbing maintenance lawfully. But be sure that you know what you're doing for the following reason. If water leakage results in an insurance claim, the claim may be rejected if the work has not been carried out by a licensed plumber. Under no circumstances should you do this type of work for a friend; if a flood or resultant water damage occurs, you are not insured.

All plumbing work should be carried out by a licensed person. The tips in this section are user maintenance tips only. Mr. H2O accepts no responsibility for any resultant damage or injury sustained by an individual attempting to perform any tasks mentioned in this section. If in doubt, please contract a professional; check that they are both licensed and insured.

The Anode is “sacrificial”, meaning that it is a softer alloy than the cylinder and all corrosion will occur at the Anode and not your cylinder.

Seven Very Good Reasons Why You Should Replace Your Anode And Tpr Valve Every 3-5 Years.

  1. Your hot water tank will last years longer.
  2. You will save money $$$ by making the tank last up to 3* times longer *(this will depend on water quality and regular servicing of your unit).
  3. You will save on the inconvenience and the hassle of frequent hot water replacements.
  4. You will save $$$ on electricity or gas when your tank is operating correctly.
  5. You will be helping the environment, (less tank replacements, less disposal at our ever diminishing rubbish dumps).
  6. You will not be wasting valuable resources (electricity, gas & water).
  7. Your hot water will be much cleaner for showers, dish washing and the laundry.

Test for Water leaks (Meter Test)

Water Meter Litres

  1. This test should be conducted for a 30 minute period, during which time no water is being used on the property.
  2. Find your water meter, which is usually located in front of the house in a covered box near the street.
  3. Write down the numbers indicated on the meter at the start of this test.
  4. Return to check the meter reading after 30 minutes have passed.
  5. If the numbers have not changed, you do not have a leak in your pressurised water system.
  6. Shut off the valves under all toilets in the house, and repeat steps 1-4.
  7. If the numbers have not changed, you may have a running toilet that should be serviced.
  8. If the numbers have changed, this indicates water consumption even though water was not being used during the test, and you may need a leak detection.
