  • My drains are gurgling and not draining. What would cause this?

    If you hear a gurgling noise, there are likely obstructions in the venting system. This gurgling is usually caused by air being forced through water in your drain. This blockage can come from a mixture of dirt and grease build up. We can fix this issue for you with our cutting-edge CCTV and diagnostic equipment. We're also available 24/7 for any emergencies.

  • Why is my water pressure low?

    Low water pressure can be caused by a number of factors from simple problems such as the shut off valve being partially closed, or the faucet being blocked. It can also be caused by blocked pipes and water leaks, or there could be issues with your irrigation system. If you notice your water bill has increased significantly you may be dealing with a leak. Call our team to identify the problem.

  • I would like to put a bathroom extension on the house, do you offer this service?

    Absolutely! Once we have the household plumbing drawings, we can design the new extension to comply with current building codes and provide you with certification once the job has been completed.

  • How do I know if I have a leak?

    There are several ways to know if you have a leak in your home. Firstly, your water bill may be higher than normal, despite your water consumption remaining the same. Secondly, you may notice low water pressure when filling the bath or shower. 


    If you think you have a leak, turn off all the water appliances in your home, including the dishwasher and washing machine. Then check the readings on your water metre. Wait 1hr then check the metre again, they should be the same. If not, you have a leak. 

  • How much does it cost for a plumber?

    The cost can vary depending on whether it’s an emergency out-of-hours call-out or a scheduled visit. The average cost of a plumber in the Northern Territories is between $100 to $150 per hour. 


    For an emergency out-of-hours call-out, most plumbers will also charge an emergency call-out fee. This can range from $60 to $100. It’s always a good idea to check how much the call-out fee is before asking the plumber to come out. 

  • My toilet won't flush. What can I do?

    There are a couple of reasons why your toilet won’t flush. First, check the water levels in the cistern. The water level should reach around 2.5 cm below the overflow tube. If not, manually adjust the ball valve. Turn the screw anti-clockwise to increase the water level. 


    A damaged or stuck flapper is another reason why your toilet won’t flush. The flapper is located at the bottom of the cistern and releases water into the bowl. Make sure the flapper is working properly. If the flapper needs replacing give us a call on 0407 692 980

  • How to know when I need a plumber?

    Most common plumbing problems like a leaking tap or toilet are not that serious and some homeowners prefer to fix them themselves. But some are more serious and always require the services of a plumber to make sure everything is working safely. 


    Here are five signs you need to call a plumber: 


    • You have no water flowing at all
    • You have no hot water
    • Your water heater is leaking
    • You have low water pressure at the taps
    • Your toilet keeps overflowing
  • Why do my pipes make knocking sounds?

    Knocking pipes is a common problem that is caused by one of three issues. Firstly, your supply pipes may be loose. This causes the pipes to knock together when the pressure increases due to a tap being turned on or off. 


    Secondly, your water pressure may be too high. In this case, the pipes will knock when the water is running. Or you may be suffering from Water Hammer. This is caused by a faulty shut-off valve which is closing suddenly when you turn the tap off. 


    All the above problems can be easily fixed by an experienced plumber.

  • Why do my drains smell?

    Foul-smelling drains are usually caused by bacteria feeding off food waste lodged in your pipes. This releases hydrogen sulphide gas which smells like rotten eggs. You can try to clear the smell yourself by using a combination of baking soda and vinegar. 


    Start by pouring boiling water down the drain. Then mix a cup of equal parts baking soda and vinegar. Pour the mixture down the drain and wait 5-10 minutes. Then flush again with boiling water. This should clear the smell. If not, give us a call on 0407 692 980.

  • Why does my drain clog and how do I unblock it?

    Most drains become clogged due to a build-up of food waste such as fat and cooking oil. You can try to clear this yourself by using the baking soda and vinegar trick mentioned above. 


    If this fails to remove the blockage, try using a sink plunger. Place the plunger over the plug hole and half-fill the bowl with water to create a seal. Now pump the plunger up and down for about five minutes. If the blockage remains give us a call on 0407 692 980.
