Low water pressure can turn everyday tasks into frustrating chores. Whether it's a slow-filling bath, a dribbling shower, or a struggling washing machine, poor pressure affects comfort and efficiency. At Citywide Plumbers, we understand how crucial strong, steady water flow is to daily life in London homes. Let’s explore the five most common causes of low water pressure and how we expertly resolve them.
1. Pipe Leaks and Hidden Damage
Cause: Even a minor leak somewhere in your pipework can significantly reduce water pressure. Water escapes before reaching the tap, which weakens the flow. These leaks are often hidden behind walls, under floors, or underground.
Fix: Our engineers use acoustic listening devices and thermal cameras to pinpoint leaks without damaging your property. Once located, we repair or replace the affected section efficiently, restoring your water pressure to normal.
2. Limescale and Debris Buildup
Cause: London’s hard water leads to limescale deposits, especially in older homes. Over time, minerals collect in pipes, taps, valves, and showerheads, narrowing the water path and reducing flow. Rust or sediment from corroded pipes can also contribute.
Fix: Citywide Plumbers will clean or replace clogged fittings, descale the pipework where possible, and install filters or softeners to reduce future build-up. Preventive maintenance is also available to keep things running smoothly long term.
3. Faulty or Partially Closed Valves
Cause: The stop valve (usually under the sink) and water meter valve (located near your property boundary) control water flow into your house. If either is partially closed or faulty, it can restrict pressure throughout the home.
Fix: We inspect both internal and external valves, ensuring they are fully open and in good condition. If a valve is corroded or jammed, we’ll replace it with a modern, reliable fitting that guarantees full flow.
4. Old or Undersized Pipes
Cause: Many homes across London were built with narrow lead or galvanised steel pipes, which simply can’t deliver the volume of water required by modern households with multiple bathrooms or appliances.
Fix: Our team can upgrade your plumbing system with larger, more efficient copper or plastic pipes. This not only improves pressure but also boosts water quality and overall system reliability.
5. Shared Supply or Pressure Zone Limitations
Cause: If your property shares a supply pipe with neighbours – common in older terraced or semi-detached homes – usage spikes can drop your pressure. Additionally, being located at the top of a pressure zone (e.g., on a hill) can limit flow.
Fix: Citywide Plumbers can fit a booster pump or break tank system tailored to your property’s needs. These systems ensure consistent water pressure regardless of external supply issues.
