Hello again!
We've had this outside drain blocked probably since we moved in nearly
5 yrs ago but only noticed it last year!I borrowed some dynarods but the damn drain u-bends around the 12-inch mark (as I remember). I also tried caustic soda (not advisable, apparently) to no avail.
Not sure where this drain leads off.
Any advice on a diy fix would be much appreciated!
Thx,
Mark Dathorne
