Hopefully you've come back and read this....
Many thanks Brian if I had half a brain I would have said the pipes are 2 foot up the wall so easily accessable if needing altering no floor lifting involved, and yes it has a drain off.
And to boot if I didn't type so quick being flash I wouldn't have to go back and keep correcting spelling mistakes, four times with this message.
Bit early but............Have a nice Christmas, no drinking and driving mate.
