What our customers say
Frequently Asked Questions
Why is my hot water pressure so weak?
Weak hot water pressure Wellington homeowners experience is usually caused by an old low-pressure copper cylinder, undersized pipework, or a system that was never designed to handle modern high-flow tapware and multiple bathrooms running at once. In many older Wellington homes, the cylinder itself is the bottleneck.
Can any home be converted to mains pressure hot water?
Most homes can be upgraded, but it depends on your existing pipework, water supply, and cylinder location. During a site assessment, we check whether your home is ready for a full mains pressure conversion or whether another solution would work better.
How long does a mains pressure upgrade take?
Most cylinder replacements and mains pressure upgrades are completed within a day, depending on the complexity of the job and any pipework changes required. We'll give you a clear timeframe upfront after your assessment.
Will upgrading to mains pressure increase my power bills?
Not necessarily. Many homeowners pair their mains pressure upgrade with a high-efficiency heat pump or continuous flow system, which can actually reduce running costs while still delivering strong, consistent pressure.
Do I need a new cylinder, or can my existing one be upgraded?
It depends on the age and type of your current cylinder. Older low-pressure copper cylinders generally need to be replaced to safely handle mains pressure, while some existing setups may only need targeted upgrades. We'll advise you honestly based on what we find.
