Hi, my bath waste pipe outside is frozen underground. I have a cast iron pipe. i have tried kettle water, sink unblocker, bicarbonate of soda, wire coat hanger but none work.
The cast iron pipe was warm when i put kettle water down the plug whole so the problem is definately underground and theres no way im lifting up slabs to get to the bottom of it.
Apart from waiting for it to thaw out, which could take days or weeks has anyone got any suggestions please??
