Thanks for your help Hugh, l am just abit concerned that the outsde toilet does not seem to flow much into the manhole but we do not use this toilet anyway but when l put rods upstream in the manhole in the direction of the outside toilet and took the plunger out a load of muck was coming out, it was doing this every time l put the rods up so l just gave up on that, but the manhole and connection into the manhole from the inside toilet is clear and flowing downstream so l just wanted to know if the waste pipe will flow freely or if it needed clearing upstream if it's just to the outside toilet or to a juntion and outside toilet to get a flow.....
Maybe l dont know but the muck upstream of the manhole might be muck from the blocked manhole as it was full to the top and squashed as if the problem had been there a while, so it might have travelled up the pipe
