SA Footy

have a pretty bad blocked drain, tried the plunger and draino, any other ideas?

Put on your shrinking cap and dive in with a tiny little pick and clear it out.

Or call a plumber.

Bi-Carb Soda and Vinegar I've heard

Hydrochloric acid.

Bundy and Coke

West End Draught, but take care not do overdo it, you'll corrode the pipes.

Be very careful but get a product called Mo-Flo

First. Go out the front and lift the (IP) inspection plate and shine a torch down the hole.

This IP will be on the boundry line, just be4 the footpath somewhere between the loo and the road..

If you see water, ring SA Water. It's there problem to fix.

They will come out and clear the blockage for nicks...

Does the loo gargle when it is flushed...?

Caustic Soda (Sodium Hydroxide) down the drain is a traditional solution.
It is available in flake form in hardware stores.

Be careful with it as it is highly alkaline and corrosive - which is why it works.
This is a situation where alkalis are more effective than acids.

Depends what it's blocked with. No amount of Draino will fix it if it's filled with rubble.

Get a plumber to run the that snake thing through.
