Start by checking whether the low pressure affects every tap or only one, and test both hot and cold water. Look for partly closed isolation valves, leaking pipes or taps, blocked aerators, showerheads, filters and water-saving devices. If you use a rainwater tank or pump, check the tank level, power supply and pump indicators, while also asking whether neighbours have the same issue or council works are underway. If the problem continues, contact your water provider or a licensed plumber, particularly if you suspect a hidden leak or faulty pressure-reducing valve.
