Needed to replace a low level traditional toilet cistern. New cistern was the same size and shape as the old one, so all old connections fitted perfectly. It took your plumber 3.5 hours to do this job which could easily be done within 1 hour. Your plumber used lots of my Plumbersmait (he didn't bring any himself) to seal the connections between the cistern and the toilet pan. Plumbersmait should not be necessary. The next day I detected a leak on the water inflow. The plumber came again and tightened the nut, so the leak was gone, however, in tightening the nut he had also turned the inside ball valve system sideways, so the whole system did not function at all. Unfortunately I noticed this only after he had left. I do not want your plumber ever to come back to my house. I have since bought a replacement ball valve system and fitted it myself. I have in the past had very good experiences with your company, but am now very reluctant to call any of your workforce out again.
