    Why Is My Water Pressure So Low? Causes & Solutions

    Why Is My Water Pressure So Low? Causes & Solutions

    Struggling with a weak shower or a tap that barely trickles? Low water pressure is a common complaint in London, especially in older properties or upper-floor flats.

    1. Partially Closed Stopcock

    The simplest and most common cause. Check your internal stopcock (usually under the kitchen sink) to ensure it is fully open. Sometimes they get knocked or aren't opened fully after plumbing work.

    2. Blocked Pipes or Limescale

    London is a hard water area. Over time, limescale can build up inside your pipes, showerheads, and taps, significantly restricting water flow.

    3. Hidden Leaks

    If water is escaping through a leak in your system, less water makes it to your taps. If you notice a sudden drop in pressure, check for signs of water damage around your home.

    Expert Tip

    If you live in a top-floor flat and suffer from chronic low pressure, installing a water booster pump may be the only effective long-term solution.
