A leaking tap in Perth is best assessed by a licensed plumber, particularly if tightening the handle or replacing a washer does not stop the drip. Even a small leak can increase water use over time, so turn off the isolation valve under the sink if water is escaping quickly. A plumber can identify whether the issue is a worn washer, cartridge, seal or damaged pipework and provide a quote before carrying out repairs. If the leak has caused water damage, contact your insurer promptly and check your policy requirements.
