Yes. I run a caravan site and have come across that problem frequently.

If so, what use are
these repair fittings?

Very little :-(

Thanks, that explains it.

Someone mentioned HDPE but I could only find MDPE, will that do? How

MDPE was used by Anglia Water to repipe our village. The engineer in charge
told me that it wasn't as good as HDPE but was adequate and cheaper.
