OVERVIEW:- Before starting toe,please check if there is a little looseness at each threaded joint. If it is,please tighten it first,so as to effectively reduce the water leakage.- Whening this water pipe for the first time,connect the faucet to one end and the nozzle to the other end,so that the nozzle is in the open state,open the faucet,slowly fill the water,first remove the air inside the tube ie the nozzle can effluent,then Close the sprinkler,then slowly extend the water pipe to the maximum,then turn off the water,open the sprinkler drain,let it retract to its original length,and thene it normally;- Connect the water pipe to the faucet,and when the water starts to be discharged,gradually increase the Water pressure,the water pipe will automatically extend and complete,and then it can beed through the nozzle;- When you are noting the water pipe,close the faucet,open the nozzle,and remove the water from the water pipe to make it shrink back to the original length.- Please pay attention to the reasonablee and extend the service life of the water pipe: under Water pressure,the water pipe can be fully extended,and even if the Water pressure is increased,the water pipe can no longer elongate due to the protection of the outer braided pipe sleeve,and does not open. In the case of the nozzle,only the pressure on the inner and outer tubes will be increased. When the pressure is large,the life of the inner and outer tubes will be endangered. In addition,when the water pipe is not ine,please discharge the water in the tube in time. Otherwise,under the long-term pressure state,even if the faucet is turned off,the inner tube will be elastically deteriorated,affecting the telescopic function!SPECIFICATION:- Material: PTE- Color: Black- Quantity:1kit
