With the toilet now level and shimmed, use an adjustable wrench to tighten the nuts on the closet bolts located on either side of the toilet base. Tighten each side a little at a time, alternating between them to apply even pressure. Be careful not to overtighten, as this could crack the porcelain.

Goal: Secure the toilet to the floor flange

  • Do not overtighten the bolts. This can crack the fragile porcelain base of the toilet, requiring a full replacement.

FAQs

Is replacing a toilet flange a difficult DIY project for a beginner, and how long does it typically take?

This project is rated as intermediate due to the precision required for a leak-proof seal and the need to handle plumbing. While the estimated time is 6 hours, beginners should allocate a full day, as unexpected issues like subfloor damage can extend the duration significantly.

Do I really need all the specific tools and materials listed, or can I substitute some for this project?

Many essential tools like adjustable wrenches, a drill, level, and screwdrivers are critical. While some general tools might be substituted, using the recommended materials like a new PVC flange, primer, cement, and a quality wax ring with bolts ensures a durable, leak-proof repair. Avoid cutting corners on the sealing components.

What's the most common mistake people make when replacing a toilet flange, and how can I avoid leaks?

The most common mistake is not ensuring the new flange is perfectly level with and securely fastened to the finished floor, or improperly seating the wax ring. To avoid leaks, make sure the flange is flush and tight, and carefully set the toilet straight down onto the new wax ring without rocking.

What are the most important safety precautions I should take when replacing a toilet flange?

Always shut off the water supply to the toilet and completely drain the tank and bowl before starting any work. Wear disposable nitrile gloves for hygiene and consider eye protection when working with tools or chemical primers and cements. A tarp is also crucial for protecting your flooring from water or debris.
