Funny how some writing on the internet forums can be taken the wrong way so easily.
The point I was making was that there were loads of posts telling the OP that this pluming was normal - it is.
I decided, in light of an experience, that I'd give a different thought and started my thread with this so the OP might have a read of it rather than thinking it was "yet another" post agreeing with the others.
The OP seemed to ignore my post COMPLETELY. If he'd read it, he might have asked why the need for photos. He might have thought about phoning the manufacturer. He might even have said, "Thank you." He might have posted a photo or two and then some of us might have seen the reason for excessive pluming.
It could easily be a fluing issue as in my case. The manufacturers can only give their best guidelines and it might not suit every single installation.
The reason I later mentioned pmt was to make light of the matter. It does annoy me, though, that when you do make a genuine attempt to help you are totally ignored.
And, before anyone thinks otherwise, I did agree with all the previous posts about the pluming and am quite happy with all the recent posts as well!!! All I was trying to do was help the OP.
