threading a smaller guage hose through a failed Hep20 pipe, possible?

[Fred Plune]

Hi there, I had a section of hep20 fail after 2 decades of home ownership, its buried under tiles.I verified which section of pipe is leaking with food colouring. instead of ripping tiles is there a possibility to thread narrow guage hose through the failed pipe? even if i had to renew it every 10 years it would still save re installing tiles.
my biggest question is what sort of connectors i would expect to find available for hep20 to connect to hose? do they make these for aquariums?

thanks

I did a 22mm acorn (brown horrid stuff) down to 15mm JG few moths ago. Worked fine. Philmaac universal coupling

I forgot to mention, the failed pipe is 15mm
so i need something much thinner than that to navigate,
any ideas? do hep20 couplings exist for aquarium piping?

How big is the failed pipe

Thread 10 mm hep2o and then use 10mm x 15 mm fittings
