Thank you for the clear and practical advice it’s saved me stress, time and money! Unvented and open vented cylinders. Mike did an awesome job! he arrived right on time and was very professional in his actions i would recommend rick’s plumbing to everyone! Plumbing and drain services, including emergency callouts. Pop (you might call it soda), particularly coca-cola and pepsi, is excellent for beating a clog it's arguably better.
