This volume expansion creates excessive pressure inside the water cylinder and must be regulated. The AVG PTR valve is designed to regulate and relieve the pressure in hot water services by dripping in a controlled manner. 2-5L a day of dripping is normal, depending on the hot water usage and the amount of heating going into the water.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"text-align: justify;\"\u003eThe AVG PTR valve is also a mechanical protection device for the hot water services. In rare occasions of faulty thermostat or heating element, the hot water service can overheat and build dangerously high pressures. When the AVG PTR valve senses this abnormally high temperature and pressure, it will dump large amounts of water in hundreds of liters for an emergency pressure relief.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"text-align: justify;\"\u003eA functioning PTR valve is a requirement by law in Australia for safety and the AVG PTR valve is approved under the Watermark standard. The AVG PTR valve comes with an insulation jacket and allows for a professional look and minimal heat loss.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"text-align: justify;\"\u003eA PTR valve usually has a life span about 5 years and needs replacing if you notice excessive water leakage in a stream instead of a controlled dripping.
