The task of replacing a toilet cistern might seem daunting, but if you approach it the right way, it can save you from constant drip drips caused by leaking toilets. Imagine the satisfaction of hearing nothing but blissful silence when you enter your bathroom, free from the annoying sounds of running water. Besides restoring peace, replacing your cistern can also reduce water waste and save you money on utility bills. Follow this foolproof guide to replace your toilet cistern with confidence and get your bathroom back in perfect working order.

Step 1: Gather Your Tools and Materials

Before diving in, ensure you have all the necessary tools and materials. You’ll need:

  • A new toilet cistern (ensure it matches your existing toilet model)

  • Adjustable wrench or spanner

  • Screwdriver (Phillips and flathead)

  • Plumber’s tape (Teflon tape)

  • A sponge or cloth

  • A bucket or small container

Having these items on hand will make the replacement process more efficient and quicker.

Step 2: Turn Off the Water Supply

Locate the isolation valve on the pipe leading to the cistern. Turn it clockwise to shut off the water supply. If your toilet doesn’t have a local isolation valve, you may need to turn off the main water supply to your home. Flush the toilet to empty the cistern, and use a sponge to soak up any remaining water. Place a bucket underneath to catch any drips during the process.

Step 3: Disconnect the Water Inlet Pipe

Using an adjustable wrench, carefully disconnect the water inlet pipe from the bottom of the cistern. Have a towel or bucket ready to catch any excess water that may still be in the pipe. Once disconnected, set the pipe aside and inspect the fitting for any damage or corrosion.

Step 4: Remove the Old Cistern

Locate the screws or bolts that secure the cistern to the wall and the toilet bowl. Use a screwdriver to carefully unscrew them, keeping track of all nuts, bolts, and washers. Once removed, lift the cistern off the toilet, taking care to avoid spillage. This is where the old towel or bucket comes in handy—place the cistern on it to catch any water trapped inside.

Step 5: Install the New Cistern

Position the new cistern onto the toilet, aligning it with the mounting holes. Secure it with the bolts or screws provided in the installation kit. Ensure the cistern sits flush against the wall and toilet bowl to prevent leaks. Reconnect the water inlet pipe, using the plumber’s tape around the threads to ensure a watertight seal.

Step 6: Reconnect the Water Supply and Test

Turn the water supply back on slowly, allowing the cistern to fill up. Check for any leaks around the fittings and connections. If you notice any water seeping, tighten the fittings gently until the leak stops. Flush the toilet a few times to ensure everything works correctly and the water flows smoothly into the bowl.

Step 7: Finishing Touches

Once you’ve confirmed there are no leaks, recheck all bolts and screws to ensure they are securely fastened. Clean up any tools and materials, and give the cistern and surrounding area a quick wipe-down. Your toilet should now be functioning perfectly with a brand-new cistern that’s both efficient and reliable.

When to Consider Professional Help
