Clever design by Melbourne plumber Norm Ladson To flush irrigation pipes, with water at the end of irrigation systems. Simply by fitting a 4mm dripper or a sprayer at the end in place of the end cap.
Norm was reading his Plumbing Industry Magazine on Mains water problems with redundant pipework, that is dead or stagnate water. Waterborne diseases can cause serious illnesses such as pneumonia, diarrhoea and blood or brain infections. In extreme cases, these illnesses may lead to death.
