Bit late with this,just before Christmas 2011 our pressure hot water tank blew.This had been installed by FPS and his team we thought about 2 1/2 years previously.
Called Engin,he agreed to replace the tank under guarantee,without charge, only afterwards did he say that according to his records the tank had been fitted over three years,he felt that although there was a three year guarantee it should really last a lot longer,What an honest trader!!
Again what else can we do but recommend him and his workforce.
