Cracked glaze on pipe

[silversurfer49]

Sorry if this is a completely stupid question. I have noticed a crack in the glaze of an underground pipe. It is not deep (only surface really) but about 3mm wide. The pipe is about 40 years old. Does it matter? If so, can I repair it to stop it getting worse? Any advice gratefully received. Picture at //www.diynot.com/network/silversurfer49/albums/

is that a pipe or a manhole channel?

It is a bit hard to be sure, but I would guess it's a pipe.

 

[silversurfer49]

It is the pipe running through the manhole, just near the house carrying kitchen and bathroom waste water.

It is an open top pipe not a closed pipe with a crack in the top. Sorry I didn't make that clear.

It`s a channel then ... not worth doing anything to it . it`ll be bedded onto concrete anyway. Just put the lid back and forget it

I agree. If you were to do any work on this channel then you would need to replace, otherwise good words from Nige.

leave well alone. the poo will have sealed it up!

Lowering the tone . In fact the uric salts would have done a better job of sealing it . I have seen a whole 4 inch pipe blocked with " limescale" from a Factory Urinal that the flush had been turned off . And I had to remove a 4mm encrustation from my Plastic underground pipes here @ home ... not mine, I might add. But 15 years at least of previous owner.
