Water leaking from piping connections directly under the Takagi water heater.

Safety first: Turn OFF power and gas. Close the cold water supply and relieve pressure before working on plumbing.

Steps:

• 1. Dry and inspect: Wipe the area dry and observe where water first appears to pinpoint the leaking joint.
• 2. Tighten unions: Gently tighten union nuts or threaded adapters with appropriate wrenches. Do not overtighten plastic components.
• 3. Reseal threads: If a threaded joint continues to leak, disassemble, clean threads, apply fresh pipe thread sealant or PTFE tape rated for potable hot water, and reassemble.
• 4. Support piping: Ensure hot and cold lines are properly supported to reduce stress on the heater connections.
