I washed out the edges of my sump plug and it is complete smooth and hence and the socket can't grab it. What can I do?

Sorry to hear of your problems.

First I would buy a new sump plug to use after you've got the old one out.

Sometimes you can get them out by hammering on a smaller size socket. A bit brutal but it does work!

Otherwise use a stillson. It's the tool that engineers and plumbers use to turn bars and pipes that are completely round. Get one with a long handle so you can get plenty of torque. Just don't do the new sump plug up with it.

Use a torque wrench to do up your new sump plug, at the correct torque setting, and use a new washer!

Best of luck, don't give up.;-)

Get someone to weld a socket onto the plug or get a set of turbo sockets which are use for removing rounded nuts and bolts

I had an identical problem. The way that I finally removed it was to use a small hacksaw and very carefully cut two flats opposite and parallel to each other on the head of the plug. Be careful to cut down only as far as the copper sealing washer and do not cut beyond the diameter of the threaded section of the plug. Then with a pair of good large molegrips, clamp across the new set of flats and you should be able to loosen.

Getting it hot with a blow lamp can work, the alli will expand more than the steel sump plug.

I had this same problem, so i used some water pump pliers the ones you can adjust the jaw opening . Bolt loosened in a jiffy.

A 1/2" inch AF socket may tap on too.
