Ron was one of the lucky ones. The fire destroyed much of his 30-acre property -- but amazingly, the house was saved. Now, as the fire season gets into full swing, Ron is using his close call to encourage others to be prepared by putting a reliable water system in place. "The week we decided to make our Flowerdale holiday house a full-time home I realised we needed a good fire system," says Ron, who is also a volunteer member of the local CFS. "I headed down to my local plumbing outlet, and they recommended a fire ring system around my house. I bought all the equipment including poly pipe, fittings and a pump." It had been a decade since the last bushfire had struck, so while Ron had the equipment on hand, it wasn't until the fires were raging nearby and the sky began to darken that he decided it was time to put his system together. Luckily it took only minutes to set up. It consisted of polyethylene pipe connected to his water tank to form a ring around the house, Philmac compression fittings to connect the pipe, and various outlets where garden hoses could be connected to help "water down" the house. The whole system was then connected to a pump to keep the water flowing. "I'd never wish to go through an experience like that again," says Ron." But it makes you realise what's important."

GF PIPING SYSTEMS' NEW SIGNET CHLORINE ANALYZER GF Piping Systems has introduced the new Signet 4630 Chlorine Analyzer System to augment their growing line of measurement and control products for potable water. Designed with amperometric sensing technology, the new patent- pending analyser incorporates a clear flow cell, flow regulator, sensors, filter and rotameter, all in one compact unit. The fully integrated system provides a turnkey solution for accurately measuring free chlorine in applications with stable pH, temperature and chlorine levels. Typical uses include water distribution, ground and surface water monitoring, HVAC cooling water, food and beverage, RO membrane protection, swimming pools, aquariums and water parks. A key feature is a built-in flow regulator that automatically controls the flow stream across the sensors membrane, resulting in reduced bubbles for improved system accuracy. The flow cell comes complete with isolation ball valves, eliminating the need to purchase additional parts -- the only requirement is a 3/8" influent and drain tubing. Installation is easy into any service point where nominal pressure is 15 to 150 psi (1-10 bar). The 4630 Chlorine Analyzer's amperometric sensor technology provides an improved solution over traditional chlorine monitoring by enabling more accurate measurement in real time and eliminating the need for reagents. Typical chlorine measurement devices, such as DPD based instruments, rely on chemical reagents, which may be out-dated or contaminated and require frequent replacement and maintenance. Other methods that calculate free chlorine measurement include the use of pH and ORP sensors. These also require frequent calibration and cleaning, and often produce unreliable readings. The new 4630 reagent-free system eliminates problems associated with chemical testing while providing a continuous monitoring solution. In addition to its simple installation, the unit's flow cell can be easily opened for thorough cleaning and removal of algae or hard water deposit build-up. The analyser comes equipped with pre-wired electronics, a 120 VAC power plug, two 4 to 20 mA outputs and two dry contact mechanical relays. The flow cell can accommodate two sensors -- one chlorine and an optional pH sensor. Other features include a bright backlit LCD display and an optional weatherproof exterior panel for outdoor mounting applications. GF Piping Systems supplies a full range of plastic pipes and fittings to Ron Litjens surveys the approaching bushfire from the roof of his house.
