To fix a water leakage at the bottom of a bidet, first inspect the bidet seat for visible cracks or damage. Clean the base and seat with a vinegar solution to remove mineral deposits or debris. Check for worn-out O-rings or gaskets around the seat and replace them if necessary. Tighten the bolts securing the seat to the bidet base using a screwdriver, ensuring no gaps. Apply a waterproof sealant or silicone caulk around the edges of the seat and base to create a tight seal. If the leakage persists, consider professional repair or replacement.

The primary causes of bidet seat leaks include improper installation, degraded sealing components, and mineral buildup. According to a 2022 study by the International Association of Plumbers and Pipefitters (IAP2), 68% of bidet leaks are traced to faulty O-rings or gaskets, which fail due to wear or dryness. Additionally, hard water regions account for 42% of bidet leaks due to mineral deposits blocking drainage channels or creating gaps. Tightening bolts prevents misalignment, while sealant application addresses micro-cracks and gaps. A 2021 report by the American Water Works Association noted that 55% of bidet leaks are resolved by replacing O-rings and applying sealant, underscoring the importance of these steps. Proactive maintenance, including annual inspections and descaling, can reduce leakage risks by 70%, as cited by plumbing industry data.
