Carefully place the tank back onto the toilet bowl, guiding the new bolts through the holes. From underneath, attach the washers and nuts to the bolts. Tighten them evenly, alternating between each side to ensure the tank sits level and secure. Reconnect the water supply line to the fill valve and hand-tighten the connection. Turn the water supply back on, allow the tank to fill, and then flush the toilet to test the repair. Thoroughly check for any leaks around the bolts and the base of the tank.

Goal: Reattach tank and verify repair

FAQs

Is replacing a toilet truly a beginner-friendly project, and how long should I expect it to take?

Yes, this project is rated as beginner-friendly, but requires careful attention to detail. Most DIYers can complete it in approximately 3 hours, assuming no major complications like flange damage. Allocate extra time if you're working alone or if your old toilet is particularly stubborn.

Besides the listed adjustable wrench, sponge, and putty knife, what other essential tools or materials might I need?

You'll also want work gloves for hygiene, a utility knife for scoring caulk, and possibly shims if your floor isn't perfectly level. Don't forget rags or old towels to protect your floor and a bucket for any residual water. A new wax ring with bolts is crucial, as listed in materials.

What are the most critical safety precautions to take when removing the old toilet, especially regarding water and waste?

Always turn off the water supply completely and flush multiple times to empty the tank and bowl as much as possible. Wear sturdy gloves and eye protection when handling the old toilet, as it can be heavy and contain residual waste. Be careful lifting, as toilets are heavy; bend with your knees.

What are the most common mistakes people make when installing a new wax ring, and how can I prevent leaks?

A common mistake is misaligning the toilet over the wax ring, which can crush it improperly and lead to leaks. Ensure the new wax ring is seated correctly on the flange or base of the toilet and lower the toilet straight down onto the bolts. Do not lift and reposition the toilet once the wax ring has made contact, as this can break the seal.
