    Look for outside manhole covers and existing soil pipes

    The water board have plans of what's in the road but not (usually) what is on your land. Where does the soil pipe from the upstairs toilet go? Can you hook into that?

    The upstairs soil pipe goes through the kitchen wall at the back of the house. I have looked for manhole covers but can't see any but the back garden is covered by grass and stones. There are no covers outside the front of the house so I suppose I need to see some sort of plans. Will the water board be able to tell me? To hook up to the existing pipe would mean going underneath the whole of the house.

    The water board are unlikely to have plans. Have any of your neighbours got manholes?

    Do the other 3 also have a soil pipe on the back wall? If so it is likely the common sewer runs along the back of the properties.
    Is your new toilet at the front? If so there may not be a drain you can connect to.

    No one buried under the patio that I know of! All the soil pipes run down the back wall in the kitchen. There is an alleyway running behind the back gardens but no manhole cover. Would the land registry know?

    You might be able to locate the drain by getting someone to flush a toilet or fill a basin and unplug it and listen outside for running water.

    It would need to be very quiet outside and would probably need a fair bit of luck.

    Alternatively, try one of these.

    I recently put in a downstairs loo/shower room at the front of the house. The bathroom is at the back like yours. There are no manholes or drain covers to be found on any of the houses in the row I am in. I guess in 1905 they didn't think they were necessary.
    I had two plumber/drain experts in who suggested major works involving taking up the concrete kitchen floor costing upwards of 4000+VAT!!! I noticed that at the side of the house there was a rainwater drain from the gutters. The local drainage map revealed that all our waste water went into a combined sewer. We were able to connect from the rainwater drain pipework and run a soil pipe under the floor boards in the house. The fall on the pipe only needs to be very slight 1:40 I think.
    I was concerned that we would hear in the lounge everytime someone flushed as the pipe under the floor but we don't

    Contact your local council's building control department and ask to see a copy of the BC plans for your home. There may be a charge for this service, so you need to find out the cheapest way of doing it.

    BC plans normally indicate where the drainage runs go, but not always.

    Manholes are frequently covered by patios, grass or debris. But some properties are connected via a branch that doesn't have any manholes. The BC plans might show you where a manhole was when the house was built or last modified.

    Ask a builder. Any decent one will suggest a solution. Forget the Council or the Water Board. They only get involved to approve what your builder does; if the work is minor, lots of builders will quietly ignore the need to involve Council Building Inspectors or the Water Board anyway.

    Try to aviod the lazy solution of a Macerator (an electric sh17 mincer)and a pump to sent the shredded poop along a narrow pipe to the nearest soil stack (the big downpipe which your exitsing khazi connects to).

    There is almost always a "gravity" solution; so the poop can flow in a wide pipe naturally to the soil stack or sewer..

    We once ran a pipe 15metres from the front of the house to the back without problem; you don't need much "fall" for easy flow.

    And you'd be surprised how easy a builder will find it to locate the sewers and drains even if they do have to lift the flooring or excavate solid (cement) floors . Ours tok about two days to excavate, move and re-lay the whole subfloor in a former garage to lay new outfalls for a new loo and shower.

    Why do the builder's job for her or him?

    Is that your best advice, find a builder who ignores building regs?

    I bet you provide your builder with somewhere to tie his horse up.
