Commercial Plumber: Upgrade to Mains Pressure Hot Water for a Better Shower Experience in Wellington

Commercial Plumber: Upgrade to Mains Pressure Hot Water for a Better Shower Experience in Wellington

If you're dealing with low water pressure in your shower, the issue likely stems from having a low pressure hot water system. At Laser Plumbing Wellington East, we specialise in upgrading homes in Wellington, Lower Hutt, Upper Hutt, and the Kapiti Coast from outdated low pressure systems to efficient mains pressure hot water systems. Making this switch can transform your daily shower into a strong, comfortable, and enjoyable experience.

Why Switch from Low Pressure to Mains Pressure?

The most common frustration for homeowners with low pressure hot water systems is weak flow at the tap or shower. Instead of enjoying a powerful spray, you’re left with a disappointing trickle. This can make daily routines less efficient and more frustrating—especially during winter.

Another common issue is poor temperature control. Many households with low pressure systems struggle to maintain a consistent water temperature when using mixer taps. The imbalance between high pressure cold water and low pressure hot water often results in fluctuating temperatures, making it hard to enjoy a relaxing shower.

Understanding the Difference: Low Pressure vs Mains Pressure

Low pressure systems were once standard in New Zealand homes. These systems use either a ceiling-mounted water supply tank or a pressure-reducing valve to lower the incoming water pressure. The hot water cylinder in a low pressure system cannot withstand mains pressure, hence the need for this regulation.

Mains pressure hot water cylinders, however, are built to handle full water pressure straight from the street mains. They provide a significant improvement in flow rate and performance. A pressure-limiting valve is added to maintain safe and consistent pressure levels throughout your home.

What’s Involved in the Upgrade?

Switching to a mains pressure hot water system involves removing the ceiling supply tank or pressure-reducing valve and rerouting cold water directly from the street mains to a new hot water cylinder. This process includes the installation of new pipework and safety valves, such as a pressure-limiting valve, to ensure optimal performance and compliance with safety standards.
