Yes Plun Bob 66 it is all very sad but you can only blame the Public / Government cos no one seems to be interested in a licensing scheme for plumbers, like most other countries have which would stop all this shoddy work in a trice.
That wouldn't stop the "friend of a friend" types that claim to be able to do these jobs despite not actually being a plumber etc. Ultimately down to customer to be more savvy & not be blinded by the fact they think friends & family won't rip them off.
