Andy, the last time I priced up those big downpipes (are those the ones you mean?) they cost ££££ very expensive I thought.
when I worked out how many I would need to fully baffle the tank I was shocked at the expense
My apologies if I have got you wrong, and maybe the drainage pipes for underground are very cheap per metre, but the other type certainly isn't!
Though it really is a very effective way of baffling your tank if it is of the unbaffled variety.

Ahh...just read the post you made as I was doing this reply.
I think we are talking about different types of pipe.
The downpipe is rigid and expensive, you certainly can't coil it.
Can you be a little more detailed on the pipe you are talking about?? Diameter and so on??
