As G&M says, see your deeds. If you've a mortgage, your lender will probably have the deeds. Some banks charge no fee for this, some charge a small(-ish) fee. Get a copy while you're at it. The Land Registry won't be far off, *probably*, but the scale of the drawing may be an issue. Deeds are interesting to look at, anyway.

Think about it - is there any way that you can run the drain internally - it doesn't have to be very large in diameter,
1 1/4" would probably be OK (if well supported).J.B.
