This Hozelock mini sprinkler is fully adjustable, meaning that the flow can be fully controlled between 0-40 litres per hour to suit plant needs. With two connections, the mini sprinkler is also suitable for using in-line to water many plants along the same line. The sprinkler is able to water up to a maximum radius of 30cm based on a water pressure of 1.5 bar. The mini sprinkler can be dismantled for cleaning to prevent clogging which can cause poor water flow. To connect the sprinkler, simply lay the 4mm irrigation tubing where you intend to put the sprinklers, and cut the line where each sprinkler should go. With both ends of the cut pipe, push them into the sprinkler and repeat as necessary. Supplied in a pack of 5. To activate your product guarantee, please register the purchase on Hozelocks website.
