Happy New Year everybody! I am seeking advice. My kitchen drain has been clogging regularly approximately every 6 months on my 14 yo home with pvc pipes. I had a local plumber come out mid summer and he seemed to resolve my last clog with his power snake. Well were clogged again after regularly using Bio Clean based on the last plumbers suggestion. I will post a picture of the current set up for possible suggestions. I used the products in the pic according to manufacturers instructions to no avail. I also snaked the drain pipe this morning with my older 25 snake. There was standing water at the base of the horizontal Tconnector which did recede once I snaked it. Temporary success only. I think I just pushed the clog as both sinks are still backed up. I am open to any tips, recommendations or suggestions.😀
