I have been training back flow testers since 1985 and it is time to retire. I will no longer teach the ASSE Cross Connection Classes. We will continue with gauge calibration, repair and building. I thank the thousands of student I have met over the last 30 years and It has been fun while it lasted but refinements and and changes in regulations and has stopped it being fun anymore. I look forward to continuing corresponds through the gauge calibration section for a while. Thanks to all Sandy lawson S & M Water Consultants. We calibrate and repair most mechanical gauges and can convert the three valve unit to the new 5 valve configuration.
