Thanks for your response.

Yes the foul-water drains were faulty as well and they have been fixed
under insurance.
But they never checked the clean-water drain even though their work
schedule said they should have!

The insurance company have told me they will check the front
clean-water drain next week and if its faulty they will fix it. I'm
hoping they will aslo fix the floor too!

But I will have to wait and see the result of the drain inspection
first!
