If that doesn't work, you may need to disassemble the connection, clean the threads, and reapply thread sealant or Teflon tape. Leaks in the valve body can be more serious. They may indicate a crack or corrosion in the valve body. In this case, the valve should be replaced. When troubleshooting leaks, always follow safety precautions. Depressurize the system before attempting any repairs. Wear appropriate personal protective equipment, such as gloves and eye protection. If you are not comfortable troubleshooting leaks yourself, contact a qualified technician. By addressing leaks promptly and safely, you can prevent further damage and ensure the reliable operation of your system.
