About Us

Originally trained as a plumber and drainlayer with one of Warkworth’s long-standing plumbing companies, Karl Oldham left plumbing and drain-laying to run his own business with his wife, Kylie.

Mobi-Kair specialises in water storage and water treatment for domestic, rural clients from Dairy Flats and Coatesville to Warkworth and north to Matakana and Omaha. From their lifestyle block in the Kaipara Hills, Karl and Kylie offer a professional, reliable water tank cleaning and repair service. They are passionate about clean water for the health and well-being of their community and their rates are extremely competitive.

Water Advice & Water Tank Services

Karl can bring his years of plumbing skills and experience to your water harvesting system. He is fully qualified to offer advice on your pump systems, filtration, spouting, guttering and pipes to ensure your water tanks free of undesirable tastes and contaminating deposits.

Ask Karl about floating water pickup and floating suction strainers. These are designed to float just below the water level to ensure you are drawing the cleanest water in your tank. They will take the water from just below the surface where it is more oxygenated and contains less dangerous sediment that can endanger your friends and family as well as prematurely shorten the life of your filters and pump.

Confined Spaces Entry

It can often be necessary to enter the tank in order to clean it effectively. They are trained and certified to work in confined spaces.

Height Safety Certification

The team has specialised equipment that lets them tackle any job, big or small, saving time, water and cost to clients, and are certified in height safety, abseil and fall protection.
