Rinnia Tankless V65I wasp nest in vent piping
A wasp nest can block the air intake, exhaust vent, or burner components of a Rinnai tankless water heater, causing the unit to display error codes, shut down unexpectedly, or stop producing hot water. These nests can restrict proper airflow and interfere with safe operation.
**South Texas Piping** can inspect your tankless water heater, identify the cause of the error code, remove any insect or debris blockage, and perform the necessary repairs to restore proper operation. Our licensed technicians will also inspect the venting system and recommend preventive measures to help keep pests from returning.
