Maintenance and service • Visually inspect the valve once a year for signs of leakage. Lifting the valve and flushing it through thoroughly will often resolve any leaks. If no leak is found, it is not necessary to lift the valve.During a periodic inspection (e.g. once every four years), the valve should be lifted to check its functionality.If the leak continues after lifting the valve and flushing it through the valve must be replaced.If the leak continues after lifting the valve and flushing it through the valve must be replaced.The Prescor valve is a safety product. We therefore recommend that it is replaced at least every 10 years. • If the valve regularly blows off during use, consult the installation specialist.
