"Update: I called pine state and spoke with George, he came by and fixed it in 10 minutes. Charged me 150$ less then ward and including parts! Go to pine state instead and save your money! Also dont be fooled by the response below. Like I said they are trying to make themselves look good and cover it up. They say they did there job by saying they diagnosed the issue and provided a solution to fix the issue. Well its not hard to diagnose an issue when it is clearly snapped off in front of you. The solution they offered, “sry we cant fix this, please call and schedule an appointment, we wont be able to come back until the end of july, or you can hire someone else to replace the whole T-set if you need water sooner.” Pine state had my water back in 10 minutes! Needless to say they are very unprofessional and rude. Extremely Disappointing Experience For full review go and look at my google review. Save your money and go to a professional! Call Pine State!"
