If water is uncontrolled or approaching electrical equipment, prioritise safety and call a plumber. The guidance below is general and does not replace an inspection.

Understanding the issue

Low flow at several outlets can relate to the incoming supply, isolation valves or internal pipework. Pressure and flow are different measurements, so a stronger-sounding diagnosis needs evidence. Ask whether neighbours or other properties are affected.

Before arranging the visit

Describe which outlets changed and whether the issue appeared suddenly or gradually.

Choosing the appropriate plumbing visit

We establish where the fault appears to sit in relation to the property boundary and internal isolation. Our mains water supply page explains the related work and how an assessment is arranged.

Where the findings point to low-flow mains investigation, read the low-flow mains investigation service details before discussing the repair scope. The actual fitting and access determine the work needed.

Information worth keeping

Record when the issue occurs, the affected room and any previous repair. For a property in our home area, plumbing in West Bridgford explains the local enquiry route; check the coverage directory for another postcode.
