Frequently Asked Questions
Why does my combination boiler constantly lose pressure?
There is leak on the combination boiler or the central heating system.
Why is my boiler on and no heat in radiators?
If your boiler is working but the radiators are still cool then the likely cause is a faulty boiler pump, your central heating controls are faulty, air in the system or the system has sludge content.
What causes mildrew in my bathroom?
No matter how well and how often you clean your bathroom, mould or mildew can spring up if you have a hidden water leak. Mould thrives on moist, dark areas, and a pipe, which is typically hidden in a wall or under flooring, provides the perfect starting point for mould or mildew if the pipe springs a leak.
Why do upstairs radiators not heat up?
Check that there is water in the feed-and-expansion cistern. If it is empty, the ball valve has probably failed or expansion vessel needs recharged.
Why does my boiler make loud noises?
Kettling is when your boiler makes banging or popping noises when turned on. It is commonly caused by a build-up of limescale or corrosion debris on the surfaces of the heat exchanger. This build-up can restrict the flow of water and cause localised boiling, which can cause hot water to turn into steam.
Why is my water bill so high?
The most common leaks are toilets.
Leaking water produces a high water bill without your knowledge. Some leaks are sporadic and require some detective work. Other leaks are very obvious. It doesn’t matter what type of leak you have, they both have solutions.
I have a waste water notice from Northern Ireland Water, what do I do?
If the leak is on a section of pipe that is your responsibility then you will have to pay for the repair. Once you become aware that you have a leak, you must take steps to repair it. If you don’t you could be wasting water, and receive a legal notice requiring you to make the repair. A cracked or damaged pipe can lose thousands of litres of water per day.
