Core plugs

[johnnywgk]

I had a core plug pop out last winter, I will replace it, but should I do all 12 of them, any help would be great as i've never had this before. TIA.

How did it "pop out" ? Block froze?

If the others that you can see look ok (haven't moved) I'd just do the one but if in doubt.......


And, of course, if the one that is out looks as if it was on the brink of rusting through it's time to do them all!

If it popped rather than corroded, maybe just the one. But as Mike asks, why did it pop?

If it's corroded then I'd do them all, as they'll fail by the law of sod when you don't want them to!

Must've been a frozen block/over heating.

The one I have to hand is as solid as a solid thing from solidsville.

Would over heating have built up enough pressure to pop it out, as I'm sure I've had more of that than freezing?
