Water pressure plays a crucial role in the proper functioning of residential plumbing systems. While adequate water pressure ensures a steady flow of water, excessively high water pressure can lead to various problems such as leaking toilets, taps, and rattling pipes. In this blog post, we will explore the causes and effects of high-water pressure in residential houses and discuss a possible solution to mitigate these issues: pressure limiting valves.
Understanding High Water Pressure
Water pressure refers to the force exerted by water as it flows through pipes and fixtures. The standard water pressure for residential properties is typically around 500kpa. When the pressure exceeds this range, it is considered high water pressure.
Causes of High Water Pressure
Several factors can contribute to high water pressure in residential homes:
Municipal Water Supply: Sometimes the municipal water supply itself has high water pressure. If the supply pressure is above the recommended range, it can affect the plumbing system in your home.
Elevation: If your house is located at a lower elevation than the water source, it may experience increased water pressure due to the gravitational force.
Faulty Pressure Regulator: A malfunctioning or incorrectly adjusted pressure regulator can result in elevated water pressure within your plumbing system.
Effects of High Water Pressure
High water pressure can lead to various problems, including:
Leaking Toilets and Taps: Excessive pressure can cause toilet cisterns and faucet seals to wear out quickly, leading to leaks. These leaks waste water and can result in increased utility bills.
Pipe Damage: Constant high water pressure can strain and damage pipes over time. It may cause joints to weaken, fittings to fail, and pipes to develop cracks, resulting in leaks or bursts.
Noisy Pipes: If the water pressure is too high, it can cause pipes to rattle or make banging noises when the water is turned on or off. This can be disruptive and indicate potential plumbing issues.
The Solution: Pressure Limiting Valves
Installing pressure limiting valves (PLVs) at the water meter is an effective solution to regulate water pressure and prevent the associated problems. PLVs act as a barrier between the main water supply and your home's plumbing system, automatically reducing the water pressure to a safe level.
Benefits of Pressure Limiting Valves
By installing PLVs, you can experience the following benefits:
Leak Prevention: PLVs ensure that the water pressure remains within the recommended range, reducing the risk of leaks in toilets, faucets and pipes.
Extended Lifespan of Fixtures: By maintaining optimal water pressure, PLVs can extend the lifespan of your plumbing fixtures, preventing premature wear and tear.
Noise Reduction: Installing PLVs can eliminate or significantly reduce the rattling or banging noises caused by excessively high water pressure.
Understanding Insurance Coverage for High Water Pressure
Home insurance policies often include coverage for damage caused by sudden and accidental water damage, such as burst pipes or leaks. However insurance companies may have specific guidelines and limitations regarding high water pressure. It's essential to review your policy and understand the coverage provided in relation to water pressure-related incidents.
High water pressure can lead to various plumbing issues, including leaks, pipe damage, and noisy pipes. To mitigate these problems, consider installing pressure limiting valves at your water meter. PLVs can regulate water pressure, ensuring a smooth and efficient plumbing system in your residential house. Consulting a professional plumber can help you assess the water pressure in your home and determine the appropriate course of action to resolve any high-pressure issues.
