I meticulously disassembled the existing toilet components, ensuring careful handling of each part. The old fill tower, flush valve, flapper, chain, and supply line were removed and replaced with high-quality new parts. Precision was key in installing the new fill tower to ensure optimal water flow and pressure. The flush valve was installed to guarantee a powerful and efficient flush. The flapper was carefully fitted to prevent any leaks, and the chain was adjusted for the perfect length to ensure smooth operation. The supply line was reconnected securely, and the toilet was tested to confirm there were no leaks. The unit is now fully operational, providing reliable performance.
