Disconnect the water supply line coupling nut from the bottom of the toilet tank's fill valve. Then, locate and unscrew the nuts and washers holding the tank bolts from underneath the toilet bowl. You may need a screwdriver to hold the bolt heads steady from inside the tank. Once the bolts are removed, carefully lift the tank straight up and off the bowl.

FAQs

What additional tools or materials, beyond the adjustable wrench and sponge, are highly recommended for a successful toilet installation?

A five-gallon bucket is crucial for collecting residual water from the old toilet. Also, have a utility knife for trimming bolt caps, rags for cleanup, and consider purchasing a new braided stainless steel supply line for optimal reliability and leak prevention.

What are the most crucial safety precautions and potential hazards I should be aware of during this DIY toilet installation?

The old toilet can be very heavy; always lift with your legs or ask for help to prevent back injury. Be extremely careful not to overtighten the mounting bolts or the tank bolts, as this can easily crack the porcelain fixture. Ensure the water supply is completely off before disconnecting anything to avoid water damage.

The project is rated 'beginner' with an estimated 3 hours. Is this realistic, and what factors might unexpectedly increase the project time or difficulty?

While 3 hours is a good estimate for ideal conditions, beginners should allocate more time, perhaps 4-6 hours, to avoid rushing. Rusted bolts, a damaged flange requiring repair, or discovering an uneven floor can significantly extend the project. Always be prepared for unforeseen challenges.

After installation, if my new toilet rocks slightly or I detect a leak, what are the most common causes and how should I troubleshoot them?

Toilet rocking often indicates an uneven floor or bolts tightened unevenly; use shims to stabilize if the floor is uneven. Leaks typically stem from an improperly seated wax ring, loose supply line connections, or an issue with the tank-to-bowl gasket (if applicable). Retighten connections carefully or inspect the wax ring if a leak persists at the base.
