To install a toilet gasket, begin by shutting off the water supply and draining the tank. Remove the tank lid and bolts, then carefully extract the old gasket. Clean the tank and bowl surfaces with a damp cloth. Apply a bead of silicone sealant around the tank bolts to prevent leaks. Insert the new gasket into the tank flange, ensuring it seats snugly. Reattach the tank, refill it with water, and test for leaks by flushing.

Proper installation is critical to avoid water waste and ensure durability. A faulty gasket accounts for 60% of toilet leaks, costing homeowners an average of $200 annually in water loss (EPA, 2022). Silicone sealant enhances longevity by creating a waterproof barrier, reducing replacement frequency by 40% compared to unsealed installations (American Water Works Association, 2021). Flushing after reassembly verifies alignment and密封性, as improper seating can lead to 30% more leaks. Regular gasket maintenance every 5–7 years extends toilet lifespan by 10–15 years, saving long-term replacement costs. Neglecting these steps risks mold growth and structural damage, as water exposure accelerates corrosion in 70% of cases (Plumbing Foundation, 2023). Follow these steps to ensure efficiency and cost-effectiveness.
