I'm renovating my bathroom and to cut a long story short when I pulled up the floor to get at the water pipes I've discovered the piping and connection system is Rehau.

After a fair bit of googling the system seems straight forward enough but a special compression tool is needed to change the fittings.

I can't seem to find anywhere that sells or hires these tools.

I'm not sure where to go from hear as my usual plumber doesn't have the tool either.
Any suggestions?
