Water Heater Installation


Why Choose Able Rooter for Your Water Heater Needs?


Installing a water heater requires expertise and adherence to local building codes. Our certified technicians will handle everything from disconnecting your old unit to connecting the new one. Here’s how we ensure a flawless installation:

1. Preparation for water heater Installation
  - Safety First: We begin by shutting off power or gas. For electric heaters, we disconnect power at the circuit breaker; for gas units, we turn the gas control valve to the "off" position.
  - Drain the Old Unit: We drain your old water heater by connecting a hose to the drain valve and opening a hot water faucet to allow air to enter.
  - Positioning the New Heater: The new water heater is placed on a drain pan in the designated area, with careful attention to ventilation and access for future maintenance.

2. Connecting Water Lines
  - Install Safety Features: We install a new temperature and pressure relief (T&P) valve, using Teflon tape on the threads, ensuring the valve points downward for safety.
  - Connect Water Supply Lines: Our team connects the cold water supply and hot water lines, utilizing dielectric nipples to prevent corrosion between different metals.
  - Add Expansion Tank: We also install an expansion tank on the cold water line to manage pressure changes effectively.
  - Check for Leaks: After turning on the water supply, we open a hot water faucet to bleed air from the system, ensuring steady water flow and checking all connections for leaks.

3. Power or Gas Connection
  - For Electric Water Heaters: Once the tank fills, we reconnect the power at the circuit breaker and safely connect electrical wires according to the manufacturer’s instructions, ensuring a proper ground connection.
  - For Gas Water Heaters: We connect the gas line using gas-rated thread seal tape, employing two pipe wrenches for a secure fit. After restoring the gas supply, we test for leaks using a soapy water solution.

4. Final Steps to Completion
  - Double-Check Connections: We verify that all water, gas, and electrical connections are secure and functioning.
  - System Startup: Once everything is connected, we turn the power or gas back on, initiating the heater's heating cycle.
  - Temperature Adjustment: After sufficient heating, we test and adjust the water temperature, ensuring it meets your preferences while checking for any drips at the relief valve.
