Practical, plain-language guidance on choosing, installing and maintaining water storage, written by the Promax team.
Spring is the turning point for a rural water system: winter has tested it, and summer demand is coming. Here's what New Zealand farmers should check and get right now.
Read the guideUnderground tanks free up land, stay out of sight, and keep the surface above them usable. Here's when they make more sense than an above-ground tank on a New Zealand property.
Read the guideSteel, concrete, fibreglass and plastic tanks each behave differently once they are holding water. Here is how the four materials compare, and what to check before you choose one.
Read the guidePromax's 1,000 litre Slimline tank is 31 centimetres wide and the same height as a fence, so it collects rainwater on sections too small for a round tank. It is stormwater compliant and every Slimline includes a built-in seismic restraint.
Read the guideLead times, raw material prices and drought all push in the same direction: buy the tank before you need it. Promax's answer was the Promax Promise, which locks in the delivery and the original price.
Read the guidePoly rainwater tank prices vary widely, and a cheap tank is cheap for a reason. The saving usually comes out of the design, the raw materials, the fittings or the warranty.
Read the guideKiwi sections are shrinking, and the Promax Slimline is built for that: a narrow tank that sits along a fence or behind the house, with seismic restraints already built in.
Read the guideENDURO tanks have corrugated sidewalls and can be inset up to 1 metre in the ground; XPRESS tanks are smooth-walled, come in two colours and carry a budget-friendly price. Both are built to AS/NZS 4766.
Read the guideEven the smallest Promax tank can provide thousands of litres of water every year. Capacity is only a guide: a tank that keeps refilling punches well above its size.
Read the guideTen questions worth asking before you buy a water tank, and where to find the answer to each one. Get these right up front and the rest of the decision follows.
