Disgusting Drains

Kitchen sink drama. The waste has been glugging and belching for some time now and repeated applications of Mr Muscle and other feeble drain cleaners has had no effect. As I can no longer get hold of a couple of hundred grams of pearl caustic there was nothing for it but to dismantle the pipes and rod out the gunge. I altered the pipe work a bit to improve the flow so it drains more completely before I put it all back.
A lot better now.
