Space, Plumbing, and Electrical Requirements

 

When requesting water heater services such as maintenance, delivery, replacement or installation, safety is top of mind. The following safety requirements must be met to protect your home and to help ensure technicians can do their work safely.

  1. There must be a functioning shut-off valve on the cold water line feeding the water heater.
    If you do not have a functioning shut-off valve, one can be installed for a $150 charge on your next NB Power bill. For more information, please inquire directly with a Customer Care Advisor during the installation or repair request.
  2. A minimum of 7”/18 cm – 10”/25 cm clearance is needed at the top of the tank and 2”/5 cm around the diameter to accommodate associated fittings.
    (See tank dimensions below).
  3. The path to the water heater must be clear and sufficient space is required for our technician to work.
    i.e. – Not obstructed by boxes, walls, appliances, snow, etc.
  4. Acceptable piping is Copper, PEX (Cross linked PolyEthylene), CPVC (Chlorinated Polyvinyl Chlorine) or Poly-B (Polybutylene).
  5. The location of the water heater should be close to a free flowing floor drain or other acceptable means of directing the water to a safe location for disposal.
