Installation Instructions

Required Tools (Not Included):

  • Crimp tool for PEX connections
  • Crimp rings for PEX connections
  • Adjustable wrench or pipe wrench
  • Thread sealant tape (Teflon tape) or pipe dope

Installation Steps:

  1. Prepare the Water Heater: Ensure the water heater is turned off and drained according to the manufacturer's instructions. Close the main water supply valve.
  2. Connect to Water Heater (FIP End): Apply thread sealant tape or pipe dope to the threads of the water heater's inlet/outlet ports. Connect the 3/4 inch FIP end of the Eastman WaterFlex connector to the corresponding port on the water heater. Hand-tighten, then use an adjustable wrench to tighten an additional 1/4 to 1/2 turn. Do not overtighten to avoid damaging the rubber washer.
  3. Connect to PEX Pipe (Crimp PEX End): Slide a crimp ring onto the PEX pipe. Insert the 3/4 inch Crimp PEX end of the connector fully into the PEX pipe. Position the crimp ring over the fitting and use a PEX crimp tool to secure the connection. Ensure the crimp is properly formed according to the crimp tool manufacturer's instructions.
  4. Check for Leaks: Slowly open the main water supply valve and allow the water heater to fill. Inspect all connections for any signs of leaks. Tighten connections slightly if necessary, but avoid overtightening.
  5. Restore Power: Once all connections are secure and leak-free, restore power to the water heater.
