Choosing a Water Tank Level Indicator for your Lifestyle Block or Bach There’s no doubt that summer has well and truly arrived, even here at the northern end of the Southern Alps. NIWA’s seasonal climate outlook is predicting near normal rainfall across the country and that’s great news for anyone reliant on rainwater to fill their water tanks. The last thing you want this holiday season is for your water tanks to run dry. If they do start getting low, you’ll need to know as soon as possible so you can start rationing. But how do you gauge the water level? Tank gauges can save you money Water tank level indicators range from simple float-based systems through to sophisticated wireless models. They’re a useful investment but like most equipment, we tend not to think much about them unless they stop working. It pays to check them now and again. We have friends who were given a free tank gauge by the company that built their new home. It never worked properly but they didn’t realise this until the following summer, when they had to get water trucked in at considerable expense. The low-tech solution The benefits of a low-tech float system lie in its simplicity. It’s inexpensive, easy to install and with few moving parts, it should last a long time. The brightly-coloured float is highly visible, so you can assess your water level at a glance. If topography or distance mean your tank is obscured from view, it’s possible to get extensions to the level float so it can be seen from further away. The high-tech solution At the other end of the spectrum, a wireless water level indicator will give you instant access to tank data via an LCD screen inside your house. A solar-powered sensor is attached to your tank and monitors the level. These systems warn of low levels or abnormally high usage levels that could point to a leak. They’re capable of monitoring up to nine tanks at once and they’re maintenance-free. Obviously, they cost more than the mechanical system. Whatever your tank gauge needs and budget, the good folk at RX Plastics have a solution to suit. Thanks for reading in 2014. Wishing you all the best for the holiday season and may your tanks never run dry!
