Blimey and I thought my end of day was bad enough! Just tiled kitchen and conservatory and cleaned up....thought I would save sparky a job (UFH) so decided to mount the back boxes for him. Drilled staright through a hidden radiator pipe in the wall. So new feature in the conservatory.....a waterfeature in the wall. Conservatory transformed in minutes into a swimming pool!!! Rushed around and found the stop ****.....old house and that was hidden away. Once I stopped the water I sat back and smiled as I was thinking, Thats one way to clean the floor! So had to chase the wall out and repair the pipe, bleed all 12 radiators. The customer came back home and fortunatley just laughed. So much for an early Friday finish.
