Tenant has reported a water leak in the bathroom. My plumber has looked at it and thinks there is a perforation in the water pipe servicing the shower unit (though he's not 100% certain) and recommends that we replace the pipe. No damage to property has been caused as a result of the leak. To access the existing plumbing, tiles will have to be broken and then replaced (we won't get matching ones, so in all probability complete re-tiling). The area then has to be sealed. I am exploring the possibility of claiming the plumbing costs, re-tiling and sealing through insurance but as there has been no damage to property I am skeptical about my chances. Would appreciate any ideas or suggestions.
