Water heater leaks from the top around piping connections.

Safety: Turn OFF power and close the cold water supply. Allow the unit to cool.

• Dry and inspect: Wipe the top of the Alpha heater dry and observe where water reappears.
• Tighten connections: Use a wrench to snug the hot and cold nipples and any unions. Do not overtighten plastic fittings.
• Reseal threads: If leaking persists, drain the system enough to remove the leaking fitting, apply fresh thread sealant or Teflon tape, and reinstall.
• Replace cracked parts: Replace any cracked Alpha top cover fittings or dielectric unions.

After repair, slowly refill and check for leaks before restoring power.
