Fitting a new toilet is a job for a professional plumber if it’s wall-mounted, a back to wall loo, or any toilet in a new setting, but if you have a close-coupled toilet to replace an old one it’s possible to fit it yourself.
This is a standard guide so make sure to follow the manufacturer’s instructions too.
Firstly – make sure the water supply is turned off at the mains or you’ll flood your bathroom. Do this by turning the household stopcock clockwise.
Let’s get to it – water removal
Flush the toilet to get rid of the water.
If there’s any left, use cloths, mops, and sponges to get the remainder out.
Now disconnect the toilet from the water supply. You’ll need a wrench as the previous plumber would have tightened everything to avoid leaks.
Moving the toilet
Your loo will be fixed to the floor with screws. Undo them and check if the cistern is also fixed to the wall. If it is, undo those screw too.
Disconnect the pipework and try to remember what went where! Take a photo with your phone if you’re unsure.
Move the loo and clean the floor up
You may find your bathroom is now filled with gases that make you heave and feel sick.
It’s the sewage fumes wafting back up the ‘stink pipe’. Stuff an old rag in the pipe and open a window quick!
We’re going to connect the cistern first
Following manufacturer’s instructions fit the flushing parts in the cistern.
The close-coupled washer is the next step, put it in place on the pan.
Place the cistern on top, fitting the flush mechanism through the washer and lining up the bolts.
Secure the bolts so the cistern sits on the pan.
Now fitting the toilet to the floor
Push the pan connector into the waste pipe after removing that old rag. Hold your breath.
Line up the waste pipe making sure the pan fits securely through the connector.
Now, is the pan straight? Use a spirit level to check the pan and the cistern. If it’s not straight use small pieces of packing to level it out.
Push a pencil through the bolt holes to mark the positions
Drill pilot holes in the floor and wall
Fit the toilet over the pilot holes and tighten the screws.
Use silicone sealant around the base to keep things neat and tidy.
Putting the water back on
Reconnect the water supply to your new toilet – check your phone if you can’t remember which pipe went where.
Turn the mains water back on and flush the loo checking for leaks as the water moves through. If you find leaks turn off the water supply and seal them with PTFE tape or silicone.
The final touches
Fit the loo seat into position. Two bolts will secure the seat to the porcelain pan. Tighten them so the seat doesn’t shift when you sit down.
Fitting a new toilet can seem a monumental task, but if you’re careful connecting and disconnecting the water supply and the waste pipe there’s nothing to it.
You just need patience and the ability to work your way through it methodically.
