Choosing new tapware is about more than just design and finish, it’s also about ensuring compatibility with your home’s plumbing system. In New Zealand, one of the key considerations is water pressure. All tapware from Newtech is designed exclusively for mains pressure systems, which are now standard in most modern homes. But if you're unsure what system you have, it’s worth taking a moment to check before selecting your tapware.
Mains pressure systems supply water at a high, consistent pressure, typically between 300–500 kPa or higher. These systems are fed directly from the street mains, providing strong, even water flow throughout the home.
Low pressure systems, on the other hand, are often found in older homes and rely on gravity-fed or valve restricted hot water cylinders. These systems typically operate at around 75–120 kPa, resulting in a noticeably weaker flow from the hot tap compared to the cold.
Because Newtech tapware is engineered to perform optimally at mains pressure, installing it in a low-pressure system can compromise both performance and warranty. That’s why it’s important to determine your water pressure early in the renovation or building process.
The easiest way to confirm your system type is to inspect your hot water cylinder. If it's clearly labelled "Mains Pressure" or "Low Pressure," that should give you a definitive answer.
If there’s no label, you can also compare the flow strength of your cold and hot taps. If your cold water flows strongly but the hot is noticeably weaker, it’s likely a low-pressure system. In contrast, if both hot and cold water flow with similar force, you’re most likely on mains pressure.
Another good indicator is your shower performance. A strong, balanced shower output generally signals a mains pressure system, while a weak or inconsistent flow often points to low pressure.
Using mains pressure tapware on a low-pressure system can result in poor performance, such as a slow flow rate or uneven temperature mixing. It can also put stress on internal components that aren’t designed for low-pressure operation. For this reason, matching your tapware to your pressure system is just as important as choosing the right style or finish.
Newtech’s Evoke Tapware range is crafted for modern homes with mains pressure plumbing. From basin mixers to showers and bath fillers, every product is designed for optimal performance under consistent high-pressure conditions. This includes premium features like Sedal ceramic cartridges and Neoperl aerators, all tested to meet AS/NZS 3718 standards for durability and pressure resistance.
A Small Check with Big Benefits
