Help! Smelly Drains. . .

Our drain outside stinks when it is in use what can I do to combat the reek?

Soap flakes (think that's what I mean - don't have any in to check) sluiced with boiling water.
Or bicarb and vinegar and then sluice that with boiling water.

i do the bicarb / vinegar / boiling water thing, it works a treat.

This but if there is a blockage further along you may have to get the big guys out x

Caustic Soda? Probably not very environmentally friendly though.

Well it's not blocked and it doesn't smell inside but when we're outside it stinks whenever water goes in if that makes sense?

I was going to stick either bleach or soda crystals and boiling water down all the pipes in the house... It hasn't helped the smell before though

Dead thing in drain?

Dead thing in drain?

Not that kind of smell...

Will blitz them tomorrow and see what happens
