I have never had a problem with drains before.
I put some Mr Muscle down the sink in the hope that would sort the drain, nothing improved. I have just put some other stuff down the actual drain outside. I have swept the water/poo mix down the drain outside and bleached the place. I got the rubber gloves out and the rod thing that came with the drain stuff liquid and there was nothing solid down there.
Could this be an issue that the drains are just clogged up due to the rain or should I be calling people and if so who?
