Purain PF 300 - 100 Inflow Water Calmer
All tanks develop sediment on the bottom over time. This is because a water tank is an eco-system and the by-product of a healthy tank eco-system is sediment. While good rainwater filtering will restrict the amount of sediment forming, its will always occur to some extent. To ensure the bottom sediment is never stirred up (which will block sprinkler heads, toilet and washing machine flush valves) the PR 300-DN100 inlet calmer is installed. The incoming water falls straight down the inlet pipe and is turned 180 degrees upwards exiting out the small holes in the top of the calmer. In this way, even if the tank is empty, upward pressurised water cannot stir up sediment on the bottom of the tank. When used in conjunction with a SAUGSAGF floating suction filter (above), pumped water quality is sediment free and will not block toilet valves or irrigation heads.
