This problem is becoming very prevalent in Harare. They combine dissolved iron with oxygen to produce a bright orange deposit which can clog pumps, filters and plumbing. We can assist. We also do camera inspections, drilling, flushing and casing and capacity testing. We install pumps, controllers, tanks, tank stands, pressure tanks and solar pumping systems.
