Many homeowners are intimidated by DIY plumbing projects. If the proper plumbing is in place, toilet plumbing installation is a fairly easy task. One does not require training and expertise to install a toilet. The following step-by-step guide outlines the process in small, manageable steps for installing a toilet.
Preparing for installation-

The first step is to unpack and check all the components of the new toilet system. Make sure the system is complete with pan-to-pan cistern sealing ring and connecting bolts, a flush valve and a fill valve, a cistern and cistern lid and flush buttons. Make sure the drain and supply lines in the bathroom are in right places. Mark the position of the mounting brackets. Turn off the main water supply valve before the toilet plumbing installation process.

Setting in the bowl-The next step is to set the wax ring over the waste drain flange. Make sure the bolts are set inside the channel and properly lined up to fit the bowl. Re-route the cold water supply before setting in the bowl. Now, lift the bowl and push it on to the wax ring. Seal the base of the toilet by using a bead of silicone caulk. Secure the position of the toilet bowl with the help of bolts. Install the washers and closet bolt nuts. Check all the bolts are fully aligned and tightened.

Level the toilet-If the bathroom floor is uneven, lift up the toilet slightly and slide a coin into the void to make sure it is leveled evenly. This will prevent the rocking of the toilet.

Install the toilet tank-The next step is to install the toilet tank and attach it with the hose of water. The tank comes with pre-installed bolts that need to be put into the appropriate holes on the toilet. The large hole in the center is connected with the gasket. Tighten the bolts that are holding the tank to the toilet base. Now, turn the valve on and check for any leaks and to ensure that the tank is filling with water.

Set the toilet lid-The final step is to set the toilet lid in place. The holes in the hing of the lid should line up with the holes in the toilet. Now, install the toilet seat at the back of the toilet bowl using a silicone sealant and a caulking gun.
