Marriednotdead: that would involve a lot of body-brushing for many dh's! Water companies in england and wales have responsibility for many sewers and drain pipes that were formally under private ownership. Used the whole bottle overnight to unblock a slow running bathroom (bath and loo) pipe water now runs freely - exceeded my expectations! There are no service fees at royal flush plumbing! you approve the price before work begins. So what should you expect from a home buyers.
