Had to have this drain unblocked professionally the other day, because I don't have the right kit. It blocks yearly, and so I'd like to be able to sort this myself.
The problem is, that the drain pipe goes in the direction of the arrow, away from the wall as shown in the picture below. My drain rods are not flexible enough to get around the corner with the wall being where it is, but the professional I got in the other day seemed to have a thinner, more flexible type of drain rod.
I searched on line, but could only find standard rods. Is there a particular name for this type of rod that might help me to source one?
(I'm in the UK if that's relevant)
