Crack in plastic drainage pipe leading from bathroom sink

[popotla]

Hi, I've just spent a good while on the internet looking for solutions but am not much the wiser. Maybe someone can kindly help.

The bathroom sink drainage pipe is made of 1-inch heavily "ridged" (or corrugated) shiny black plastic (very firm, doesn't compress when I squeeze it with my hand), which for a reason I can't imagine has at one point developed a circumferential crack most of the way round (not far to go until it's severed, in other words).

Sealant and/or tape - perhaps a tape which contains a sealant (?) - seems the obvious way to go. I'm not experienced with these things, though, so might be wrong.

Should such a repair work OK and can you please recommend a specific product or products? In fact I'm in Germany but there has to be a local equivalent of what's available in Britain.

The obvious way to go is to buy some new pipe and change it, taping it up will not be any good.

Agree with Mikeco,your local caravan shop should keep the correct size pipe.

I always keep a roll of self amalgamating tape for that very reason. You stretch it to about 3 times its length and wind it around, it sticks to itself and seals no problem. You can buy it from any chandlers shop

Cut out the bad section and join backtogether - add a new short piece of needed.

Self amalgemating tape may do the job.
It has to be stretched as its put on to ensure a seal.

Funnymunny types faster than me.

The thing is that from the bathroom (and the slide-away sink), the pipe disappears into the depths and is very difficult to access. Thus I'm hoping to avoid a replacement.

self amalgamating tape ........ stretch it to about 3 times its length and wind it around, it sticks to itself and seals no problem.

This is standard koi pool pipe, sold in almost any aquarium shop and in Germany Kölle Zoo is a dead bet or any Hornbach as they always have an aquatics sections. Cheap as chips unless you go to the MH dealer...

Three weeks ago I used "self-amalgamating tape" (only - no pipe replacement, which would have been difficult/tricky) and so far there is no leakage.

Thanks for all advice.
