Before and after
What the homeowner called about
A homeowner in Broken Arrow called us for yearly maintenance on their tankless water heater and noticed the unit was leaking.
What our plumber found
Our plumber inspected the tankless unit and found that the leak was coming from the condensate line connection, which used a brass fitting with PEX.
How we fixed it
Our plumber removed the brass fitting, expanded 3/4 PEX tubing, and ran a short one-foot line directly to the drain to stop the leak while completing the annual service.
More from this visit
Travis handled this visit for our crew, with annual tankless service and a reported leak both on the job record. Our service included descaling the heat exchanger with the chemicals used for flushing the unit.
Our annual service also included checking all the fittings and all the filters on the tankless unit. We addressed the condensate connection as part of the same service visit, rather than treating the leak as the only item on the job. The record does not document separate testing results or any filter replacements.
Signs to keep an eye on
- Watch for drips or moisture around your tankless water heater and its condensate drain connection.
- Keep the condensate drain path clear, and have visible leaks checked rather than ignoring them.
- Follow your unit’s maintenance guidance for descaling and filter checks.
What this means for your home
Scheduling regular yearly maintenance for your tankless water heater helps catch small plumbing issues like condensate line leaks early.
