Leaking Hot Water Cylinder? Need to Fix it?

If you notice that your hot water cylinder is leaking, a professional repair and replacement should be in order. Leaky hot water cylinders can occur due to numerous reasons, and if not fixed quickly, they can cost you money by spiking your water and electricity bills.

How to stop your hot water cylinder from leaking and minimise the damage it can cause?

Follow these below-mentioned steps if you see drips or pooling around your water heater.

  • First things first, turn off the water supply. Push the supply pipe’s valve in the clockwise direction to shut the water from entering into the cylinder. If you are unsure about which tap to turn off, turn your main stopcock off. This will shut down the water supply to the entire house.
  • Next, switch off the power supply to the hot water cylinder. Turn off your heater and boiler so that the elements of the cylinder are not at the risk of burning when the leftover water drains out.
  • Attach one end of a hose to your cylinder drain valve, while laying the other end outside your sink. This will drain the hot water cylinder much faster, and the leak will stop as soon as the cylinder empties.
  • Contact reliable plumbers for professional repair or replacement of the hot water cylinder.

If it is a T&P valve, pipe or plumbing leak, a simple repair by a qualified plumber will do the job. However, if the hot water cylinder is not heating/ functioning properly and the leak is located on the cylinder, you may have to replace the whole unit.

These appliances have a lifespan of about 15-20 years. If your appliance is old and worn out, it is best if you replace it with a new one rather than spending your money on costly repairs.
