• Fire Tank Couplings

  In areas where reticulated water supply is unavailable or insufficient there is a requirement for alternative water sources for fire fighting purposes, Big Water Tanks is the first to bring to market the most efficient and most cost effective siphon fire coupling system.
  
  Large holes for fire couplings in bottom of fire tanks cause huge stresses in the plastic material at the bottom of the tank, our competition make heavier fire tanks to accommodate for these stresses based on FEA (Finite Element Analysis - Computer aided design) costing about $1000 more for of each tank. Our Unique system uses a siphon made from very cost effective PVC pipe with a PSL fire coupling made from precision machined in heat treated alloy.
  
  These adaptors fit the requirement as per the New Zealand Fire Service Fire Fighting Supplies Code of Practice SNZ PAS 4509:2003

• Installation and Maintenance

  ◄Single Tank installation

  

  
  
  

  Step 1
  
  Bury the capped end of the pipe about 300 - 500mm into solid ground.
  
  

  

  Step 2
  
  Next install a 100 mm inspection port (90 deg tee) with our custom 100mm BNext install a 100 mm inspection port (90 deg tee) with our custom 100mm BSP PVC to DWV fitting with the FRT fire coupling 500mm from ground level.
  
  Install a 100mm PVC pipe with sufficient length to reach above the overflow height and allowing the pipes and fittings to enter through the top of the tanks.

  

  Step 3
  
  Install another inspection port with the cap on the side to break the siphon if required
  
  Install another TEE with the open ends facing each Tank
  
  Then on both side a 100mm PVC pipe to a 45 bend to go through the tanks with a rubber tank seal, then another 45mm bend is installed inside the tanks with a pipe to the base of both tanks.

  

  Step 4
  
  The bottom of the pipe needs 4 x 40mm (75mm from bottom to centre) holes drilled into it for suction..

  

  ◄Double Tank installation

  

  Step 1
  
  Bury the capped end of the pipe about 300 - 500mm into solid ground.
  
  *Additional requirement:
  Install a 100mm breather to the top of the tank.

  

  Step 2
  
  Next install a 100 mm inspection port (90 deg tee) with our custom 100mm BSP PVC to DWV fitting with the FRT fire coupling 500mm from ground level.
  
  Install a 100mm PVC pipe with sufficient length to reach above the overflow height and allowing the pipes and fittings to enter through the top of the tank.

  

  Step 3
  
  Install another inspection port with the cap on the top to break the siphon if required.
  
  Then out of that a 100mm PVC pipe to a 45 bend to go through the tanks with a rubber tank seal, then another 45mm bend is installed inside the tank with a pipe to the base of the tank.

  

  Step 4
  
  The bottom of the pipe needs 4 x 40mm (75mm from bottom to centre) holes drilled into it for suction..

  

  ◄Maintenance

  Maintenance
  
  The best way to keep round thread clean is to fit a blank cap or the new anti-vermin guard (included with the kit).
  
  If the fitting has dried out and cap does not rotate freely spraying silicon, CRC, WD40 or any similar product in the back where the cap swivels will make this rotate better and stop binding on the Aluminium.
  
  CRC Marine spray all over the fitting, will dry so it is not sticky and will protect it from the elements.

  ◄What Fittings are require?

  Fire Fighting Fittings

  Our Managing Director had been for a few years a volunteer fire fighter at a rural brigade north of Auckland, while these water storage tanks and FMJ fire fittings are required on most new builds we would like to give the opportunity to retrofit our system to any tank, if its full or not.

  Fire safety is something to be taken seriously, we have worked with Ahuroa Brigade and upgrades the stations system to test our larger sized siphon system, we installed an extra shutoff valve on there system so they can use the water at any time. 

  ◄How does Delivery work?

  Pricing

  Please use the checkout procedure for estimates on freight, we reserve the right to cancel an order if freight is incorrectly calculated by our website, our site cannot calculate some rural areas or island deliveries, we will contact you if there is an issue with a freight costing to your location.

  We Deliver Water Tanks throughout the North of North Island, Our rates are based on distance, that makes us a bit more expensive for "far away" deliveries we can arrange freight to most islands, please call us or contact us with your address and details we can confirm the price for the delivery

  ◄Can we have multiple fire tanks?

  Multiple Tanks

  We have a system developed that works on one or two tanks, the tanks will self level under a siphon and will balance through a smaller base connection

  ◄What is the Volume of the Fire Tanks

  Tank Volumes and a standard 45,000 litre fire tank 

  An average requirement for water tanks storage volume of 45,000l of fire fighting is quiet often the volume required for onsite storage for fire fighting in many district councils, sometimes this number is less or more depending on a large number of factors.
