Job location: Flower Mound, TX

A residential tankless water heater in Flower Mound received a full service including filter cleaning, descaling, and P-trap maintenance. The technician replaced a corroded condensation drain line with PVC piping after discovering the original PEX fitting had deteriorated on the acidic drain line, preventing future damage.

Key Facts

Today, we were called out to a residential home to service a tankless water heater and repair a condensation pipe that had come disconnected. Upon arrival, we noticed that the condensate line was installed using a PEX fitting on a highly acidic drain line, causing it to corrode and deteriorate. We serviced the water heater, cleaning the cold water intake filter, the condensation P-trap, the air inlet filter, and descaling the unit. We also replaced the condensation drain pipe with a PVC pipe to prevent any further problems.
