Unexpected water consumption
Unusual consumption can be caused by changes in usage, faulty cisterns or concealed leaks. A moving meter with no apparent use is a clue, not proof of where a leak is located.
USEFUL INFORMATION
Practical guidance, clearly explained.
Learn about common symptoms, maintaining water systems and avoiding unnecessary water consumption. Not a substitute for an on-site assessment.
Does a damp patch mean a pipe is leaking?
Not always. Water ingress, condensation and moisture remaining in materials can produce similar symptoms. Evidence from the property and installation should be considered together.
Water is an essential resource. Every drop matters.
Checking leaking taps and toilets, monitoring unusual bills, maintaining networks and considering appropriate flow-saving or flood-warning devices can reduce avoidable waste.
HIDROTAVI may offer selected water-saving and monitoring products in the future. There is no online shop at this stage.
Drainage system warning signs
Leaks associated with appliance discharges and ingress during rain may justify a targeted inspection. CCTV images alone do not prove the whole pipe system is watertight.
