Our first time to deal with irrigation system because the weather is just too hot killing our lawn..
the problem is , to cover the whole area we need 5 sprinklers, but when we increase to 5th , the 5th one cant work well
Should we simply change the type of sprinklers for better coverage ? any solution ?
We do have one hose (which connects two sprinklers) excessively long - tomorrow I will shorten it to see if pressure increase
