Complete waste of $260 to clear a drain line. Failed in less than 2 weeks. When I initially called in to have them come back out the phone operator told me it wasn’t warrantied so they couldn’t come out. I told him the tech said he would come out if it failed in less than 30 days. So he changed his mind and sent the guy out. Guy came out again tried to clear it and said it was clogged and to call a plumber. He was nice though. Just a complete waste of my money.
