If any of the above sound familiar, it’s time to look into toilet cistern replacement.
Before starting the replacement process, you must gather all the tools and equipment that are required, like an adjustable wrench or spanner, Flathead and Phillips screwdrivers, a Towel or sponge, a Bucket, a Spirit level, Silicone sealant or plumber’s tape, and a new toilet cistern.
Locate the isolation valve near the base of the toilet and turn it clockwise to shut off the water. If there’s no valve, turn off the main water supply. Flush the toilet to empty the tank and soak up any leftover water using a towel or sponge.
Carefully unscrew the inlet pipe connected to the bottom or side of the cistern by using a wrench. Keep a bucket nearby to catch any remaining water.
Most cisterns are bolted to the toilet bowl and wall. Use a screwdriver and wrench to loosen these bolts and screws. Carefully lift the old toilet cistern off the bowl and set it aside.
With the old cistern removed, this is a good time to clean the top of the toilet bowl and the surrounding area. Remove old sealant or residue to ensure a secure fit for your new toilet cistern.
Place the new toilet cistern on top of the bowl, aligning it with the bolt holes. Follow the manufacturer’s instructions for positioning and securing it.
Reconnect the water inlet pipe to the new cistern using plumber’s tape or a sealant to ensure a tight fit. Double-check that all connections are secure but not over-tightened.
Turn the isolation valve or main water supply back on and let the cistern fill. Test the flushing mechanism a few times to ensure everything is functioning correctly. Look for leaks at all connection points. Tighten gently if needed.
If there are no leaks and the flush works smoothly, your toilet cistern replacement is complete! Clean up the area and dispose of the old parts responsibly.
