Expert Tips

Q: There are strange noises coming from my hot water storage system. What could it be?

A: You’re probably hearing sediment or hard-water scale that’s accumulated at the bottom of the tank and broken off. In this case you’ll have to drain the tank and clean out the sediment. According to all major water heater manufacturers, the storage tank in your water heater needs to be drained and flushed free of sediment every 12 months. To make sure that this is done correctly, you should call a licensed plumber.



Q: Why is my tap still dripping even though I've changed the washers?

A: Many home owners will go about replacing their own tap washers, only to find the tap still drips after the new washers have been installed. It’s best to call your local plumber to take a look at the problem. He will have a special tool that can be attached to their drill which will clean the tap seat to make sure the washers sit flat when the spindles are pushed against them. If it is something else causing the problem – he’ll be able to diagnose and fix that too.



Q: Why is the water pressure low in my shower?

A: It might be time to change your showerhead. If you haven’t changed your showerhead in decades or if you’ve installed a low-flow showerhead, this could be the reason why you’re experiencing lower water pressure. Another reason could be corrosion inside your pipes. Over a period of time corrosion and build-up can happen inside the old pipes, especially if they’re galvanized. Replacing old and corroded pipes can drastically improve your water pressure. Call your local plumber to take a look and they can advise the best course of action.

A: Flexible braided hoses can definitely be a ticking time bomb underneath your sink and cause a lot of damage if they burst.

Ensure that everyone in your home knows where the main water valve is located so you can turn off your water in the event of a burst pipe.



Q: My gas storage water tank is running out of hot water a lot sooner than it used to. What could be causing this?
A: If you are getting some hot water, but not enough, your tank might need to be drained of sediment (caused by mineral deposits in water). Other causes could be the thermostat, a faulty thermocouple or a faulty pilot light. Gas water heaters can be dangerous, so finding the problem is a job best left to a registered gas plumber.



Q: My water bill just keeps going up. How can I reduce water usage in my home.

You could install water saving shower heads, a dual- flush or a AAA rated toilet, limit showers to 5 minutes and don't leave taps running. But one of the effective things is to have leaking taps (especially garden taps) and toilet cisterns repaired quickly.



Q: How long should a storage gas hot water system last?
A: A traditional storage tank water heater should last for 10-12 years, but there are things you can do to extend its life.

If you have this anode replaced every 5 years, along with an annual service, your storage heater could last for an extra 5-10 years.

Drain blockages can be caused by a number of things from hair to tree roots, so it's best to call in the professionals. They have the expertise and equipment to discover the problem, and fix it.
