Mains Pressure vs Low Pressure
Do you know what pressure system your building uses? Because it can make all the difference.
A lot of older buildings in New Zealand will have a low pressure hot water system, so here are some ways for you to check:
1) Is there a noticeable difference in pressure between the hot and cold taps? Is the cold tap more powerful than the hot? If yes, there is a high chance your system is low pressure.
2) Check the hot water cylinder for labels. Low pressure cylinders may not have any identifiable labels but mains pressure generally have a large label.
3) Can you see a vent pipe poking out of your roof or over a gully trap? A mains pressure cylinder is closed-vented so you won’t find a vent pipe.
A bathroom renovation is a perfect opportunity to upgrade an old low pressure cylinder to mains pressure.
Advantages of mains pressure:
- A large proportion of single lever tapware in today’s market are only suitable for mains pressure.
- Water is delivered to the whole building at the same pressure so it is less affected by multiple water demands.
- Reduces temperature variations in the shower which is an inherent problem with most low pressure systems. E.g. hot water turning cold in the shower when another tap is turned on.
