CTC water heater leaks from the top around piping connections

Safety first: Turn off power and close the cold water supply. Relieve pressure by opening a hot water tap.

Steps to check:

• Inspect the hot and cold water connections at the top of the heater for visible drips.
• Tighten threaded connections slightly with a wrench; do not overtighten plastic fittings.
• If leaking persists, shut off water, disassemble the joint, and reassemble using new dielectric unions or nipples and fresh thread sealant or Teflon tape.
• Replace any cracked plastic fittings with approved metal or high-temperature plastic parts.
