If your toilet is old and in need of repairs, it is cheaper to replace it by installing a new one. This is quite easy to do and can be completed in an afternoon. However, if you plan to install a toilet in a new location, you will have to extend supply pipes and drainpipes to the desired spot, a job you may want to leave to a plumbing contractor.

Most toilets are sold with the necessary gaskets, washers, and hardware for fitting the tank to the bowl. However you might need to buy a few parts. Here is a list of what you need to complete this task:

Parts: Toilet bowl, Toilet tank, Toilet seat, Two 1/4" bolts for bowl to flange, Wax ring, 20" water supply with fitting at valve or floor connection and Tools: Pair of channel pliers, bucket, screw driver.

(Many of these can be ordered online at any DIY website such as DIY Tips UK: http://www.diy-tips-uk.com/plumbing/)

1. Shut off the water to the toilet, use a bucket and a cloth or a sponge to remove the water left in tank and bowl after you flush the toilet.

2. Using a pair of channel pliers, or a small pipe wrench (8"), remove the nut where the water line fastens to the ballcock valve under the left side of the bottom of the tank. Next use a small crescent wrench, remove the two 1/4" nuts holding the bowl to the floor flange. Remove old toilet. Remove the water line from the valve or fitting at floor or wall.

3. Now you are ready to install your new toilet. Put the two 1/4" bolts in the side holes of the flange with the bolt head in the flange. Put some of the old wax at this spot to hold the bolts straight up and across from each other. Put new wax ring on flange, flat side up if tapered.

4. Set new bowl only straight down so it centers on wax ring and both bolts come through holds on each side of bowl. Sit on bowl facing wall until your weight puts bowl flush with the floor. Put metal washers and nuts on bolts and tighten until snug. Do not over-tighten as you can crack the bowl. Tighten these again after toilet is completely installed and filled with water.

5. Next put 2" rubber gasket on tank where it sets on the bowl, put rubber washers on bolts provided under the bolt head so they will be on the inside of the tank. Pick up tank and set on bowl over holes in bowl where bolts go through. Sit on bowl facing wall. Put bolts on from the inside of the tank into holes in bowl, put on metal washers and nuts and tighten. Hold tank level and tighten so it brings tank down level. Use a large screw driver inside tank and a crescent wrench or end wrench to back up nut under bowl. Tighten with screw driver. Hook water supply to tank, turn on water, check for leaks, and snug up the bolts holding bowl to floor. If there is a space between the back of the tank and the wall, put a spacer of sort there to brace tank. A piece of wood or hard rubber works fine.

Maintenance:

At least twice a year clean out the inside of your toilet tank. When cleaning the toilet tank, turn off the water, flush toilet once, add small amount of cleaning detergent inside tank to water remaining and use a cloth or brush to clean. Also clean out holes under toilet seat and rim of the bowl as well as the 3/4" hole in the bottom of toilet bowl. Replace rubber tank ball at this time if needed. Maintaining your new toilet will keep the plumber away and reduce your plumbing bill.
