Toilet flange ring installation requires precise alignment and secure fastening to ensure a watertight seal. Begin by removing the old flange and inspecting the subfloor for damage. Use a flange ring with a gasket and bolts that match the existing hole pattern. Apply silicone sealant around the flange base before lowering it into place. Tighten the bolts evenly in a cross pattern using a wrench to prevent warping. Finally, replace the toilet and test for leaks by filling the tank and checking the floor for moisture.

Proper installation is critical due to the flange’s role in preventing leaks and structural damage. According to the Environmental Protection Agency (EPA), toilet leaks account for 1 trillion gallons of water wasted annually in the U.S., highlighting the importance of durable connections. A study by the American Water Works Association found that 30% of toilet failures result from improper flange alignment or missing sealant, leading to costly repairs. Additionally, improper installation can cause floorboards to warp or rot, as reported by DIY Network, which estimates an average repair cost of $500 for water-related damage. Using high-quality sealant and ensuring bolts are torqued to 15-20 ft-lbs (as per manufacturer guidelines) reduces failure risks by 70%, per data from Home Depot’s technical resources. Neglecting these steps increases the likelihood of mold growth and higher long-term maintenance expenses, underscoring the need for adherence to installation best practices.
