Commercial Tankless Rack Maintenance in Slidell
Restaurants, salons and multi-family buildings often run several tankless units linked together. Commercial racks see heavy use and scale faster than home units. We descale each heater, check cascade controls and balance the load across the system. Quarterly or semiannual service keeps the hot water flowing during busy hours.

Noritz Tankless Water Heater Descaling in Slidell, LA
Noritz tankless heaters are known for their robust build. Our descaling service for Noritz units focuses on their intricate heat exchangers, which can be prone to scale buildup from mineral-rich water. We use manufacturer-approved descaling agents and follow precise flushing procedures to avoid damage. We also inspect the fan motor and exhaust system for proper airflow, a common area for attention in Slidell.
Inlet Filter and Air Intake Cleaning in Slidell
Every tankless unit has an inlet water screen that catches grit and scale flakes. Those screens can clog with sand and debris, especially after municipal line work. We pull and clean the screen and inspect the air intake filter, which can load up with dust and dryer lint. Clean filters keep the flow sensor reading correctly and the burner breathing properly.
Residential Tankless Water Heater Flushing in Slidell
Private wells serve many rural homes, and sediment, iron, and bacterial contamination make periodic well testing a good habit. Hard water can lead to heavy mineral buildup in tankless water heaters. Our residential flushing service in Slidell involves circulating a descaling solution through your unit's heat exchanger to remove calcium and magnesium deposits. This process restores efficiency, prevents overheating and extends the life of your appliance, so your family gets continuous hot water without interruption.
Commercial Tankless System Checks in Slidell, LA
Commercial tankless water heaters face higher demand and require more frequent, rigorous maintenance. Our service for businesses in Slidell includes detailed inspections of multiple units, checking for proper gas pressure, water flow rates and exhaust venting. We look for any signs of wear on components like igniters, sensors and heat exchangers, which is crucial for businesses that rely on consistent hot water, such as restaurants or salons.
Rinnai Tankless Water Heater Service in Slidell
Beau's Plumbing specializes in the maintenance of Rinnai tankless water heaters, a popular brand known for its efficiency. Our technicians in Slidell are trained on Rinnai's specific diagnostic codes and service protocols. We handle common Rinnai issues such as error code 11 (ignition failure) or flow sensor malfunctions, so your unit operates at peak performance according to manufacturer specifications and local codes.
Isolation Valve Kit Installation in Slidell, LA
Some tankless heaters were installed without service valves, which makes proper flushing impossible. We install a set of isolation valves with purge ports on the hot and cold lines so future maintenance takes minutes. The kit also lets you shut off water to the heater without closing the main. It is a one-time upgrade that pays for itself in easier service.

Annual Tankless Water Heater Inspection in Slidell
An annual inspection of your tankless water heater in Slidell is a smart measure against costly repairs. Our thorough check includes examining the gas line connections for leaks, testing the pressure relief valve, inspecting the igniter and cleaning the air intake filter.
