Flood risk is now a fact of life in the UK. Reports of flooding are now, on average, twice as frequent as they were one hundred years ago and experts from the Met Office and world leaders in climate change predict we could see a significant increase in flood risk in the coming years.

Unfortunately, we are currently in a position where insurance is not sufficient to protect our homes and contents against the risk of flooding. Although insurance will generally repay the cost of building repairs and contents replacement, insurance won’t protect against the distress and inconvenience caused by relocating to temporary accommodation for lengthy periods. Nor will it protect against a potential fall in the value of a property.

But crucially, it won’t stop future insurance premiums and excesses radically increasing, often beyond the reach of householders. Indeed, some properties become uninsurable if subjected to repeated flooding.

It has therefore become the responsibility of the property owner to try and minimize the costly damage caused by flooding and sewage contamination during these natural disasters.

Flash-flooding, by its very nature, is usually fast and sometimes unforeseen. The Association of British Insurers estimates that 90% of flood damage is caused by the first inch of water. This can cause back pressure of the sewage system, to such an extent that cast iron drain covers can be lifted out of place creating fountains on our streets. Similarly toilets can start to spill out sewage into properties at this early stage of flooding, so if it were possible to significantly reduce the time and effort it takes to deploy substantial defences, then many vulnerable buildings could be protected. There are products currently available on the market that go some way to achieving this aim, however they can be punctured or ill-fitted. However if defences could be installed in under a minute without the need for inflation and be rigidly fitted then that would represent a significant breakthrough in flood protection technology.

It is these observations that have been pivotal to the conception and design of these innovative Flood Toilet Sewage Stoppers which instantly provide the user with a quantum leap forward in assurance of their effectiveness.

Why and where flooding occurs.

Generally speaking flooding occurs on floodplains – from bursting river banks, in coastal regions – when sea defences are breached and near water courses – from flash flooding. However, properties half way up a hill and miles from water sources may also suffer localized flooding should a sewer pipeline become damaged for instance by growth of tree roots, or perhaps by the build of fats, oils and greases.

Flooding on hillsides away from rivers.

Flooding due to back-pressure of sewer systems is less understood by the general public. This may repeatedly occur to a single building or a small group of properties when pipe carrying capacity lower down a hillside become restricted by one means or another.

Fats, Oils and Grease, (FOG) are commonly the cause of hillside flooding (as indeed elsewhere). During heavy rainfall partially blocked drains which fail to transport the increased water flow, cause the fluids to back-flow due to the build up of pressure leading to its release at the point of least resistance, (i.e.) toilets. As these are always connected to the foul water sewer system such reverse flow of effluent usually contains raw sewage, (i.e.) untreated human excrement.

Whilst the expensive installation of underground non return valves (NRV) is protective (unless the NRV is blocked with FOG) they do simply re-route leakage to the next point of least resistance, (i.e.) the next toilet(s), either your own or next door’s toilet(s) or the nearest manhole in your garden!

Flood Toilet Sewage Stoppers are therefore the ideal new solution to these many problems as they are so obviously, visually effective, that the DIY user can have complete self assurance that their toilet will not overspill human waste into their bathrooms or public rest rooms and to subsequent floor level or basement rooms.

The disposable covers, being so relatively inexpensive, would enable an owner or occupier to protect their toilets whenever they perceive that flooding is likely or when away on holiday as the Flood Toilet Sewage Stopper may be used repeatedly and is small enough to keep available by the toilet and needs no other items to either fit in place or remove in seconds.
