Anyone know if this hole in pipe is meant to be there?

Hello all

I just noticed this hole in my outside bathroom sink pipe and wondering its meant to be there or if not, how and with what should I fill it with?

Thanks al

No, someone made a hole in it to clear a blockage. Use a suitable sized bolt, or wooden plug, to fill it.

The picture shows an inspection/access hatch within a few inches of the hole, so it would be a bit bizarre to deliberately make the hole to clear a blockage.
The hole looks to me caused by rust, so the area around it might be fragile also.
I would carefully clean off all the paint around the hole (about 1/2in all round, inspect for rust and treat with converter, and then patch the hole with some perforated zinc sheet and 2-part filler paste. That also avoids creating an obstruction within the pipe which using a bolt would do.

Old trick, knock a small hole with a hammer and push a piece of wire through the wall part. That's definitely what it is.

Not if you don't screw it in too far.

You can see where the previous hole repair has peeled off.

If you clean the paint off, you may be able to use a stepped drill and drill it out to 20mm, this is a common size for bungs, blanking plugs, blind grommets etc. Stick one in with some silicone then the following weekend paint over it again and forget about it.

All to complex for me DIY wise.

I have bought some of this.
Would this work?.
Only thing I was worried about is it falling inside before its dried.
