This galvanised tank failed spectacularly when a large chunk simply fell away and the whole tank emptied on to the attic ceiling in seconds. There was no shut-down valve and the water flooded the house for over 2 hours prior to the arrival of Emergencyplumber.ie. The ceilings were left sagging with pools of water present in all areas of the attic. This galvanised tank should have been replaced many years ago in order to avoid this type of failure.
Cheap Ballcocks causing leaks:
Here is a cheap plastic and brass ballcock that was removed from a water tank in the Clonee area. Very poorly made with plastic nuts and plastic outlet. It failed where the arm meets the body when a chunk of the plastic sheered off. This should have been an all brass ballcock.
This tectite elbow was forced onto a 15mm chrome pipe connected to a radiator. The water leaked through the ceiling into the kitchen of the house concerned. The leaking water was coming from between the brass body and the plastic 'collar' of the fitting. 14.7mm connections forced onto 15mm pipe is a common problem in Dublin as plumbers rarely carry 15mm connections.
