Have you had any contact with the freeholders? Who is currently repairing the leak and dealing with the consequential damage.
It sounds as if your lease is clear in that it should be the freeholders paying for that. I would start down that route and then get into discussion on the quality of the installation and your concerns.
Oh and random documents relating to gas and water installs might steer you in the right direction of how it should be done, but don't expect them to be of any more use to you than that.
