Help with non existent pipe fittings!!

[Jennifer cutts]

First of all I know nothing about plumbing I apologise for any errors. This is for connecting mains water to a caravan.

I need to link a black 28mm (pvc?) mains water pipe that cannot be pulled up or replaced into a 25mm mdpe pipe.

The 25mm connects to 15mm in the caravan, so the 25mm could potentially be changed but I can’t find any fittings for 20mm or 32mm either.

So I have searched for a 28mm - 25mm reducing tee to no luck also tried an equal tee to a straight reducer and found nothing.

I’ve rang every plumbers merchant in the county please can someone help with either the correct fitting or a working alternative.

Thank you!!

Well the black pipe you have could be Alkathine old imperial size what you need to do is cut off a small pice take it into your local plumbers merchants they should be able to sort it out for you

I can’t cut the pipe unfortunately.
Would that mean it isn’t 28mm but 3/4 so I’ve been searching for the wrong thing?

I would think you have the old 3/4" class c black alcathene water pipe.

28mm isn’t 3/4 unless we’re talking internal
