Holman's new "twist control" flow connector, helps any garden hose or irrigation line to save water! A simple twisting action of the connector body, reduces the amount of water flowing through the connector and into your garden. The 12mm quick release coupling, makes it easy to add the water saving flow connector ANYWHERE into a system. Applications: The flow connector has a variety of uses. Reduce and save water to either new or existing poly pipe systems, restrict watering in dripping hoses running through garden beds. Systems using drip style irrigation work best with a controlled water supply. Even install onto a garden hose to govern the amount of water delivered to a lawn sprinkler or watering nozzle. Individual control: Quite often when watering from one water source (garden tap), you may find you have many products using this one source. Each garden hose or poly pipe may require a different water flow. The flow connector is IDEAL for controlling each line "individually", so your tap remains unchanged and each garden section, gets only the water it needs!
