Before dismantling the old toilet, turn off the water at the mains by locating the stopcock and turning it clockwise. Use a cup, sponge or towel to remove as much water as possible from the toilet bowl and cistern. Have a bucket to hand to collect the water. Remove the screws from the base of the toilet and from inside the cistern if it is attached to the wall.
Gently detach the old toilet from the waste pipe. You can push a cloth into the pipe to help stop smelly gases from spreading. Assemble and fit the flush mechanism and inner parts of the cistern. Attach the close-couple washer to the top of the pan. Then, carefully lift the cistern into position, making sure that the flush mechanism thread fits into the washer and that the bolts sit comfortably through the holes in the pan.
Secure the cistern to the pan by hand tightening the supplied washers and wing nuts onto the bolts. Align the waste pipe to the pan connector and attach, making sure the pan goes right into the connector collar.
Use a spirit level to check that the cistern is level. A magic eraser is a common choice, but scrubbing with mineral spirits will also work. Yes, PEX can be used to plumb a toilet and is generally a more affordable choice of pipe which is well suited for DIYers.
Hopefully, this guide has given you everything you need to get started, and you're now able to successfully plumb your toilet.

The next step to installing a toilet takes some strength, another pair of hands, and make sure you lift with your legs, not your back. Straddling the toilet bowl lift and set it over the anchor bolts then rock on the toilet till the wax ring is sealed.
Using your hand tighten the nuts over each anchor bolt, shimming as needed to keep it level. Then take your adjustable wrench and tighten off each nut doing a half turn and moving between the bolts until they are tight but not too tight. Using the mini hacksaw you can cut the flange bolt down so you only have between a quarter and half an inch extending above.
When installing the toilet take care not to bend the bolt. Now you can install the bolt cap, in some cases you might need the putty to fill it and in other cases, the cap just snaps on. Place the anchor bolts for the tank in the holes so you have where to aim when you place the tank. Now lift the tank over the bowl of the toilet, this is another step where another person is handy. If you can't find what you need, show your photo to someone in the plumbing department and they should be able to help you.
In our case, we placed the flange repair ring the white ring shown in the photo below into the existing flange and secured it in place. Before you move on, be sure to position the new bolts that will hold your toilet in place. Below you can see our bolts positioned in our flange repair ring. Step 4 — Now it's time to install your new wax ring. Since our cement tile is quite thick, we used an extra thick wax ring. We rested the toilet bowl upside down on some soft foam mats and attached the wax ring to the bottom of the bowl.
We prefer this as opposed to positioning the wax ring on the floor before lowering the bowl onto it because you can be sure the ring is in the perfect position before putting the toilet into place.
Step 5- The moment has arrived! You can now place your toilet bowl onto the flange. Be sure to align the bolt holes with the bolts in the flange. Once it's in place, press down to set the seal. Just be careful not to move or tilt the toilet because you could break the wax seal, which would mean leaks. Not good. Step 6- Place a washer and nut on each toilet bowl bolt and tighten them. Don't over-tighten—you could crack the porcelain.
Then use a hacksaw to trim off the excess bolt. You want to cut them short enough that the plastic bolt caps can snap into place. Step 7- If your toilet isn't all one piece most aren't , you are ready to attach your tank to the toilet bowl.
Align your tank bolts with the holes in on the toilet bowl and lower your tank into position. Then secure it by tightening the bolts. Step 8- Last step!!!!
