I am looking to have my current attached garage converted into a playroom with a small room within containing a toilet and hand basin.
I have had a couple of builders round to check my ideas out and they are getting back to me after first contacting the local council and sketching some ideas etc etc.
I have done some reading on the internet and my query is really with the waste from the toilet in particular and the basin.
The existing upstairs toilet is in the only bathroom and is on the opposite side of the house from the garage, the waste pipe goes directly down into a cupboard downstairs which is no good as it's not in reach at all.
But we do have a manhole cover outside the front of the garage between our property and next door.
What can go through the manhole as in waste? Can toilet waste go into this, as when I mentioned this, both builders seemed to agree and will check, but reading some posts on here etc seems to suggest that man holes are only for guttering water etc.
Any information would be great.
