The drain in my back garden is badly blocked, housemates just washing food and hair straight down the plug hole. Is there a go to brand of drain unblocker? I've used caustic soda before which worked well on internal drains, can't seem to find it on the shelf anywhere. Thought I would see if there's a better alternative if I'm having to order something online anyway.
