Mobility wetroom disaster

[Bizzylizzy]

Help I need advice! My 90 year old father in law just had his bathroom converted to a wetroom in his sheltered housing flat. It's an AKW system with pumped drainage and a seamless non slip flooring. It all looks fantastic until you turn the shower when it floods the entire room including cupboards. The waste pump only works while the shower is on. As soon as you turn off the shower the pump goes off leaving most of the room flooded and 24 hrs later no change. I bought a rubber squeegee mop to shift the water in the direction of the drain but it doesn't go down. It took me half an hour on my hands and knees with a bucket and cloth to clear it.
I will call the council but as they have already been out to inspect the finished work any advice on what's wrong and what needs to be done now would be most welcome. It a ground floor flat at the end of the building so I don't understand why there isn't simply a drain hole to take the water away.

It does over run for a minut or two but it's not enough to make a dent in the flood and by the time I pushed the water towards it was too late

 

[Bizzylizzy]

Surely the plumbers should of checked it all worked before they left?

it shouldnt be flooding that much, at most there should be a light skim of water no more than 1-2mm max

Ah thanks that's helpful - it's a couple of inches deep not a small room either!
