I'm looking for a reliable handyman to replace the toilet flush valve in my bathroom. The current unit leaks occasionally and sometimes runs after flushing. I have already purchased a compatible replacement kit for a standard close-coupled toilet and can provide it on the day. Please confirm you can handle shut-off valve access, drain pan protection, and proper reseating of the new flush valve to avoid future leaks. Flexible on timing, but I’d prefer a morning slot and note if any extra parts might be required.
