soil pipe base loose

[sammoseley]

Hi
took down a cast iron soil pipe to replace most of it with plastic apart from bottom section. when I had removed most of it I found the bottom section which I previously assumed was solid moved around a bit where it hits the ground (which is about 2' of concrete). It won't pull out, but moves up and down by a couple of inches. Concrete is right up to it so can't see anything.
I've no idea whether it's always been like that, just held together by the rest of the stack above, or whether I caused it when I dismantled the rest of it.

Anyone any idea whether this is OK or something wrong underground meaning I need to start breaking up the concrete to investigate ?

Cheers
Sam

if the water is getting away and theres no smell id say it would be ok.

cheers chukka, time will tell if theres any smell as only done it today!
I was worried about the clay having been broken underground but can't really see how i would have managed to do that so fingers crossed its OK.
