Gardena Junction box
Hello all, We would like to install a Gardena irrigation system in our garden, for which I have the following question: Between the water tap and the junction box there is a 15mm Gardena flex hose, 10 metres long. Can this lead to pressure loss? If so, how much? We already have borderline low pressure on the pipe and a pressure loss through this hose would therefore be problematic. Thank you for your help.
