Common Water Pressure IssuesLow Water Pressure

Low water pressure issues are among the most pervasive in terms of plumbing maintenance issues, characterised by weak flow from faucets, showers and fixtures.

Possible culprits may include mineral build-up in pipes, corrosion of plumbing lines or undersized supply pipes limiting pressure delivery to fixtures and faucets.

Reduced water pressure can be extremely frustrating and seriously compromise daily tasks such as showering, dishwashing and laundry.

Fluctuations of Water Pressure

Fluctuating water pressure occurs when its flow varies unexpectedly and leads to inconsistent performance of plumbing fixtures. The cause could lie with either municipal water suppliers, ineffective pressure regulators, or issues within home plumbing systems themselves.

Fluctuations in water pressure is often an uncomfortable and inconvenient reality, especially during showering or when using appliances.

High Water Pressure

High water pressure occurs when an excessively large volume of water flows through pipes at rates exceeding recommended limits, exceeding what would normally be allowed by pressure regulators and thermal expansion mechanisms, or when supplied from municipal systems at increased rates.

Potential causes could include malfunctioning regulators, thermal expansion issues or increased municipal supply pressures causing excessive flow to go beyond recommended guidelines.

High water pressure can put strain on plumbing fixtures, increase leak risks and waste water resources.

Utilising special equipment and diagnostic techniques, they assess pipes, fixtures, pressure regulators and other components before drawing conclusions about any resulting pressure issues.

Pipe Cleaning and Descaling

In cases where mineral build-up or corrosion in pipes has caused low water pressure, a professional plumber may use hydro-jetting or chemical treatments to clean them out and restore optimal flow rates.
