Hi,
Just to pass on my recent experience regarding a blocked drain. Had a blockage, drain man came out and could'nt shift it. The blockage was out under the road. Southern water came out, they could'nt shift it. They told me it was my responsibility even though it was in the road. I got on to Southern water who assured me it was my problem. I told them that the drain was right under the bus stop out-side my house. They still did'nt want to know. Drain man put a camera down and found collapsed drains under the bus stop, now they have to dig up the road. Luckily my insurance will cover it.
So beware--check whose responsibility your drains are.
