Toilet installation can sound daunting, but with the right approach and expert advice from Citywide Plumbers, it can be straightforward and stress-free. Whether you're replacing an old unit or upgrading your bathroom fittings, this guide will walk you through the essential steps to properly fit a new toilet. While DIY installations are possible, professional support ensures safety, accuracy, and compliance with UK regulations. Here’s a breakdown of how to install a toilet in just three clear steps.
Step 1: Prepare the Area and Remove the Old Toilet
Before installing a new toilet, it’s vital to ensure the existing space is clean, dry, and free from any plumbing faults.
1. Shut off the water supply
Turn off the isolation valve to stop the water from entering the cistern. Flush the toilet and soak up any remaining water with a sponge.
2. Disconnect and remove the old toilet
Unscrew the fixings that secure the toilet to the floor and detach the water feed. Carefully remove the old toilet and place a rag over the waste pipe to block any odours.
3. Check pipework and surface
Ensure that the floor is level, the waste pipe is in good condition, and there’s no water damage. Any issues here can cause leaks or future instability. Our team at Citywide Plumbers always inspects and, if needed, repairs the surrounding area before fitting the new toilet.
Step 2: Install the New Toilet Pan and Connect the Waste Pipe
Once your working area is ready, it’s time to fit the toilet bowl, also known as the pan.
1. Position the pan
Place the toilet pan over the waste outlet to ensure a perfect fit. Use a pencil to mark the fixing points on the floor.
2. Secure the waste connection
Apply a flexible connector or pan collar to link the pan to the soil pipe. Make sure the connection is tight and watertight, avoiding awkward angles that could cause future blockages.
3. Fix the pan to the floor
Drill pilot holes in the marked spots and secure the toilet pan using strong screws and caps. A layer of silicone sealant around the base provides added grip and hygiene. At Citywide Plumbers, we only use high-grade materials that last for years.
Step 3: Fit the Cistern and Restore Water Supply
The final step is installing the toilet cistern, ensuring it fills properly and flushes without leaks.
1. Connect the cistern to the pan
Use the provided bolts and washers to fix the cistern to the pan, ensuring a snug and even connection. A rubber gasket is fitted between them to prevent leaks.
2. Reconnect the water supply
Attach the water inlet hose to the fill valve inside the cistern. Turn on the isolation valve slowly and check for drips or leaks.
3. Test the flush and inspect
Once the cistern is full, flush the toilet several times to ensure the water flows correctly. Examine all joints and seals for any leaks. If everything works as expected, the job is complete.
At Citywide Plumbers, we always test installations thoroughly and provide advice on how to maintain your toilet and avoid future issues.
