Insert the new closet bolts into the slots on the newly installed flange. Place two wax rings directly onto the flange, one on top of the other, to ensure a thick, reliable seal. Carefully align the holes in the base of the toilet with the closet bolts and lower the toilet straight down onto the flange. Press down firmly to compress the wax rings. Place the washers and nuts onto the bolts and tighten them down, alternating between sides to ensure even pressure. Use an impact driver or wrench, but finish by hand to avoid over-tightening. Snap the decorative bolt caps into place.

Goal: Toilet Installation (Installing a new toilet.)

  • Do not slide or rock the toilet once it is placed on the wax rings, as this can break the seal.
  • The nuts should be snug, not excessively tight. Overtightening will crack the porcelain base of the toilet.

FAQs

How long does a toilet flange replacement typically take for a DIYer?

This intermediate DIY project usually takes between 2 to 4 hours to complete, assuming no major complications. Factors like severely rotted subfloor or rusted bolts can extend the timeline, so allocate extra time if you anticipate these issues.

What are the absolute essential tools and materials I need for this job if I don't have everything on the list?

You will absolutely need an adjustable wrench, screwdriver, putty knife, and a level. For materials, a new DANCO Perfect Seal Toilet Wax Ring with Bolts is critical, and a new toilet supply line is highly recommended to prevent future leaks.

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 flush it to drain the tank and bowl completely before starting. Wear gloves to protect against unsanitary conditions, and use caution when lifting the toilet as it is heavy and can be awkward, potentially causing back strain or damage.

What's a common mistake beginners make when installing a new flange, and how can I avoid it?

A common mistake is not ensuring the new flange is level and at the correct height, flush with the finished floor. This can lead to an improper seal with the wax ring and subsequent leaks. Use shims if needed to achieve a perfectly level and secure installation.
