The Fernox System Health Check provides all the necessary apparatus required to gather samples for testing. The micro-bottle kit consists of two sample bottles (75ml), a water analysis order form and a Freepost envelope. The process is simple. Simply fill one sample bottle with system water and the other with mains water (i.e. kitchen tap), complete the enclosed order form and return the samples and questionnaire in the Freepost envelope. The results will be returned directly to the customer. Results can also be downloaded from the Fernox System Health Check Portal.
