I received an email from Sprinkler Warehouse asking if I could answer a question from a fellow customer. I could answer the question, but when I tried to respond by pressing the answer question link in the email I got an error message "Invalid Input - Please press your browser back button, blah blah, etc.". I browsed the forum for the specific question, but couldn't find it. The question was regarding a leaking Rain Bird XBD-80 Drip Irrigation Water Emitter. Any ideas?
