Aye - Prior to 1937 (Amazing what you learn when you look into these things) It was perfectly acceptable to run surface drains into the sewer. As bubbly says it is illegal to do the reverse and, because of this, a washing machine or dishwasher now needs to be connected to the foul water or deep drain rather than the surface drain. Our drains - being both, are OK to run anything into but the downside is the situation we are now in.

The septic tank people may be an option - Thanks for that idea. I'm still waiting for the man from Dynorod to let us know how quick thay can do it. Fingers crossed. And legs seeing as we have to limit our visits the loo!
