Hi , I’m Jon Lewis.
About Me
I’m a specialist in water protection with a focus on cross-connection control surveying and backflow prevention device installation, testing, and maintenance.
Since 2014, through Backflow Prevention Ltd, I’ve dedicated my work to education, surveying, and auditing backflow prevention programmes across New Zealand. My priority is ensuring that the potable water supply — from the source to the last flowing tap — remains safe and free from contamination. With many years of hands-on experience, I can help you protect water services both inside and outside the property boundary.
