RPZ Testing and Service

An R.P.Z. valve is designed for use in commercial and industrial applications to avoid back syphon-age and pollution of the potable water distribution system. These valves are subject to an annual test by the local water authority which can only be carried out by an accredited tester. All ultravalve's service engineers are certified by WTI to carry out testing and service work on these devices. All our engineers also hold National Water Hygiene cards.
