Low pressure at a single tap often points to a local fitting, aerator, valve or pipe issue. Low pressure throughout the property can have a different cause.
Understanding the issue
Low pressure at a single tap often points to a local fitting, aerator, valve or pipe issue. Low pressure throughout the property can have a different cause.
What to check
Compare hot and cold outlets and ask neighbours whether they have the same issue. Check that internal stop valves are fully open and look for signs of leakage.
When to get advice
Do not confuse flow rate with pressure. A proper diagnosis considers supply conditions, pipe sizes, restrictions and the type of hot-water system.
