    Hi,

    I'm planning to add an extension with an ensuite shower room to the side of my house at ground floor level. However the existing bathroom with its svp is on the opposite side of the house. It is about 12.5m from the new toilet to the existing svp which I was hoping to connect into.

    As the house has a suspended timber ground floor (with a 550mm clearance from underside of the joists to the concrete below) I am wondering whether it is better to run a 110 dia waste pipe below the floor boards into the existing svp or take the waste from the new ensuite directly outside and into the existing public sewer which is approximately 25m away and will require the formation of a man hole at the connection point.

    Thanks,

    Al.

    Providing you can obtain the falls and the pipe diameter of the existing SVP/run is sufficient to receive additional waste, then go for that option, which appears to be the most cost effective?

    What has your local BCO recommended... if anything?
