Compulsory annual check of your drinking water system
Good management requires annually checking all return flow inhibitors in your drinking water system. Properly functioning return flow inhibitors ensure that your drinking water system remains clean. Keeping our drinking water distribution network clean is a high priority. The water companies actively and strictly monitor compliance with the regulations. As such, the authorities have made annual checks of return flow inhibitors compulsory in the NEN1006 standard and Water Worksheet 1.4G.
