How to Change a Hot Water Cylinder

At Plumbing Angels, we understand the importance of having a reliable and efficient hot water system in your home. However, when it comes to replacing a hot water cylinder, many homeowners may feel daunted by the process. But fear not, we’re here to guide you through it!

Step 1: Turn off the power and water supply

Before you start any work, make sure to turn off the power supply to the cylinder and isolate the water supply. This can usually be done at the fuse box and stopcock respectively. It’s crucial to ensure the electricity and water are both switched off to avoid any potential accidents.

Step 2: Drain the old cylinder

Next, drain the old cylinder by connecting a hose to the drain valve and directing it into a suitable drainage point. This will prevent any remaining water from spilling out onto your floor. If you’re unsure about where to drain the water, our team of experts can advise you.

Step 3: Disconnect the old cylinder

Once the old cylinder is drained, it’s time to disconnect it from the pipework. Carefully unscrew the connections and remove any insulation or jackets that may be covering the cylinder.

Step 4: Install the new cylinder

Now it’s time to install the new cylinder. Make sure the new cylinder is compatible with your current system and carefully fit it in place. Connect the pipework to the new cylinder and ensure all connections are tight.

Step 5: Fill and test

Once the new cylinder is in place and connected, it’s time to fill it up and test it. Turn on the water supply and fill the cylinder, then turn on the power supply and switch on the heating. Check for any leaks and ensure the cylinder is working efficiently.

Step 6: Tidy up

Finally, tidy up any mess and dispose of any old parts or insulation. We’ll always make sure to leave your property as we found it, if not cleaner!
