l will try and sort some paper work out for you and send it to you.
We was given the paper work 4 weeks ago and it has been translated into english.
The reasons we had it fitted.
(1) We have got quite a high water table on our land and if we had of had the normal type that people are saying one flush and it would of been overflowing into our garden also if we had excesive rain.
(2) As and when we enter the EU the ordinary type possibly will become illegal,We decided to do this to satisfy ourselves and also for a selling point of view if ever we wanted to re-sell.IT HAS A 10 YEAR GAURANTEE.
l can understand people saying how can they make the ordinary one illegal.
But who would of thought years ago asbestos roofs would be illegal how many people have still got asbestos as garage roofs (US FOR ONE)
WE THOUGHT IS WAS BETTER TO BE SAFE THAN SORRY AND HAVE IT DONE NOW.
bye for now Viv and Jim
