Hi their, I've been called to a job to re establish the water to a toilet block. The plumber who was last their installed 4macorators and 4new f,o,v. He didn't turn the water on and diddnt do anything up tight,when I put the water on it all leaked like a siv!! So I tightend everything up and wired the units but one of the f,o,v was leaking so shut off the service valve and left the macorator live.got paid and advised them to get new f,o,v,which they replyed (no will just close that toilet) so left and today got call saying the toilet bowl is filling up with water. But before I left I flushed every toilet 6times with clean water and everything was fine. I can't understand why the bowl is filling up? Their wasn't a blockage when I left so think they been touching it and now blameing me. It doesn't look like the toilets are linked together so can't se it being induced siphonage but didn't install them just powered them up and turned the water on can you help me many thanks danny
