Fire Coupling to Tank Installation:

  1. Install the Water tank onto a very well compacted base of GAP7 or Sand, alternatively the tank can be installed onto a concrete pad, ensuring the concrete pad is level.
    Ensure the prepared base is large enough that the tank has at least 200mm all the way around the tank.
  2. Install a Concrete Pad to mount the Fire Coupling, this needs to be at least 400x400 and can be a precast block or poured concrete. The centre of the Block must be approximately 300mm away from the tank.
  3. Using a spirit level mark the level of the concrete pad on the tank, then measure up 200mm on the tank to mark the centre of the fitting cut-out, cut out tank with a 121mm hole saw.
  4. Install Tank Fitting with the female hole on the outside, then install the threaded Nipple, then the Ball Valve, then the Fire Coupling (have the bracket between the ball valve and coupling) with Thread Tape or Thread Sealer.
  5. Fasten the Bracket to the Concrete with appropriate fixings ensuring the bracket is centrally located between the ball valve and coupling allowing for expansion and contraction of the tank.

Alternatively if access is difficult into tank, drop a rope down the manhole and grab it through the hole in the tank, install tank fitting buy dropping the fitting down a rope with the male end of the fitting sicking out the tank, then install the tank fitting nut on the outside and install the ball valve directly to the tank fitting without the nipple. Be careful not to cross thread the threads.

Tanks are not installed with tank fittings from the factory in order to get the correct heigtht of the tank fitting.

80mm Balancing Pipe Installation:

  1. Install tank fittings 150mm up from the base with a 95mm hole saw, install, install pipework with hose tails and Hose Clamps, it is recommended to get a register plumber to install this kit. Allow for a bend in the pipe to allow for expansion.
