If you fit a Lavac and follow the installation instructions carefully you will be able to say good bye to toilet problems

Whats happened to the scchoolmistress this would be a great one for her
Problem now resolved! Blockage located and cleared, and having contacted Jabsco they're sending replacement parts, which was unexpected and great! Thanks very much everyone who responded to this thread
