New build flood

[Nic161]

The bottom house of our new build flooded, clear clean water with no smell or noise to indicate a burst pipe and it was a large amount of water in approx 20-30 mins. Third party plumber (hired by builders) couldn’t identify source but confirmed it wasn’t the mains or toilet overflow. We’ve also had boiler and water tank serviced with no issues and confirmed not the overflow. Leads me to believe it must be a drainage issue but fact water was clear means NHBC have ruled that out and are refusing to advance claim. Any advice or suggestions what could have caused this? Thanks.

With everything turned off, check to see it your water meter is turning, if not check outside for puddling in grass areas, is this new build on a flood plain?

Ask the builder for his insurance details, that should prompt then into action, tell them if the issue is not resolved within (say seven days) you will be moving into hotel accommodation at his expense until it is.

Thanks for your reply. It is on a flood plain unfortunately but there has been little to no pooling of water on the grass outside even in heavy rain. There was also water works going on around that time, maybe a coincidence but unable to determine who was working on it. Builder and council said it wasn’t them. Will check the water meter thanks.
