How to Replace a Toilet: complete Guide

**Comprehensive Guide to Professional Toilet Replacement**

Undertaking a toilet replacement requires a systematic approach to ensure a successful and leak-free installation. This guide outlines each step of the process, employing professional practices to guarantee the integrity of the new toilet fixture. Whether you’re replacing an old toilet for efficiency or aesthetic reasons, adhering to these instructions will help you navigate the procedure with confidence. It’s important to note that while this guide provides comprehensive instructions, if you’re uncertain about any step, it’s advisable to consult with a qualified plumber to ensure a seamless and trouble-free installation. With attention to detail and the right tools, you can accomplish a toilet replacement that meets the highest standards of functionality and reliability.

Certainly, here’s a revised version of the instructions with a more professional tone:

**Toilet Replacement Procedure**

**Step 1: Water Shut-Off and Drainage**
Initiate the process by turning off the water supply. Locate the shut-off valve, typically situated either on the wall or floor adjacent to or behind the toilet. This valve regulates the water flow into the toilet’s supply line and tank. The tank contains the flushing water, while the bowl is responsible for the flushing mechanism. Flush the toilet to drain the water from both the tank and bowl. Since the water supply has been closed, the tank won’t refill. Employ a plunger to clear any remaining water from the drain line. Remove residual water from the tank using a sponge and a bucket. Note that a small amount of water left in the bowl won’t spill if the bowl remains upright.

**Step 2: Disconnecting the Supply Line**
Use an adjustable wrench to disconnect the supply line. This line is linked to the water pipe that supplies water to the bathroom and the toilet’s fill valve situated at the toilet’s base. If the supply line connection has not been removed for a long time, applying a penetrating catalyst like PB Blaster can help dissolve any corrosion. Be cautious not to damage the water pipe or its connection while attempting to loosen the supply line. Expect a slight amount of water to spill when the supply line is removed. Be prepared with materials to clean up any spills.

**Step 3: Separating the Tank from the Bowl**
Carefully detach the tank from the bowl. If working solo, this step may be easier to manage. Note that some toilets have one-piece construction, eliminating the separation of the tank and bowl. To remove the tank, loosen and remove the bolts from the underside of the tank, using an adjustable wrench. These tank bolts extend from the interior of the tank to beneath the bowl. It might be necessary to stabilize the upper end of the bolt inside the tank while unfastening the nut beneath the bowl. Lift the tank straight upwards. If you encounter resistance, gently twist from side to side to release the flush valve gasket binding the tank to the bowl.

**Step 4: Removing the Toilet Bowl**
Detach the floor bolts anchoring the bowl to the floor. Pry off the toilet bolt caps if necessary, using a screwdriver. Employ pliers or an adjustable wrench to loosen and remove the nuts and washers from the bolts that secure the bowl to the floor. If rusted, PB Blaster can aid in loosening the nuts. In case the nuts can’t be fully removed, turning them a few times creates space at the base of the bolts for a hacksaw to cut them. If your new toilet comes with replacement bolts, ensure the toilet bowl is free of caulking around the base before proceeding.

**Step 5: Removing the Old Toilet Bowl and Wax Ring**
Gently rock the toilet bowl to detach it, exposing the old wax ring. The wax ring creates a waterproof seal between the toilet flange and the floor’s drainpipe. Inspect the flange; if damaged, consider a repair flange or replacement. After removing the old bowl, assess the condition of the bowl bolts within the flange. If necessary, install new bowl bolts. Dispose of the old wax ring and clean the area.

**Step 6: Installing the New Toilet Bowl**
Position the new wax ring onto the flange. Carefully lower the toilet bowl onto the flange, aligning the bolt holes with the flange bolts. Press down firmly to establish a secure seal. Avoid moving or tilting the bowl after setting the wax seal to prevent damage to the seal.

**Step 7: Attaching the Tank to the Bowl**
If not already connected, place the tank-to-bowl gasket on the flush valve’s base and insert the tank bolts from within the tank. Align the tank over the bowl and secure by evenly tightening each tank bolt until they pull the tank down onto the bowl.

**Step 8: Reconnecting and Testing**
Reconnect the supply line to the fill valve. Slowly turn on the water shut-off valve to allow the tank to fill. Test the toilet by flushing and closely observe the base and tank-to-bowl connection for any leaks. Consider using leak-detecting dye for easier detection. Finally, install a suitable toilet seat according to the manufacturer’s guidelines.

Remember, if you are not comfortable with any part of this process, it’s advisable to seek assistance from a professional plumber to ensure a proper and leak-free installation.
