PEST UK can't guarantee that installing a sewer one way return valve to stop rats coming from the sewer into the drain will resolve the issue, however in a lot of cases they are successful in preventing rats accessing a property.
A large proportion of rat problems stem from sewers. Breaches in sewers under buildings can be costly and time consuming. Repairs to sewers may run into thousands of pounds. If the infestation originates from a sewer then future problems are likely unless the sewer issue is addressed. Baiting some sewer related rat problems just does not work as the rats that are killed from eating the bait are replaced by ‘new’ rats from the sewer.
Relief from rats can be for longer periods in lightly infested sewers. It may be that rats are getting into the structure of the building via a broken or cracked pipe, a ‘bodged’ connection, often found in kitchen and bathroom extensions, or a missing vent guard. Rats and sewer problems are just not restricted to inside buildings (although this is the most serious, time consuming and costly) but they may burrow out of compromised sewer systems in open ground and the rat population will spread out in the surrounding area.
How our treatment works
Initially the technician will use test bait to confirm the presence of rats in your drains. They will then carry out a camera survey of the drains near or under the building around the external wall/sewer point for a distance of up to 3-metres to identify if a breach has occurred. The specialist camera we use is extremely high quality and designed to identify any holes accessed by rats. The footage is recorded onto a memory card which can be played back on a TV.
If rat activity is confirmed the technician will fit a sewer one way return valve in the appropriate location. This allows sewage to flow out but prevents rats going ‘up’ the sewer, as well as preventing backups of sewage from entering the property. It may be necessary to fit more than one sewer valve if the property is in a terrace of houses, block of flats or semi-detached house.
If the drain is operating without leaks, smells or earth getting into it then this will instantly solve the problem for a fraction of the cost of digging up and replacing the drain.
A baiting program will clear up any rats outside the resealed sewer system after the sewer one way return valve has been fitted.
These photo’s show sewer valves fitted by Pest UK. The valves in both pictures are in the ‘shut’ position which prevents rats from travelling any further up the sewer and into the building. The flap only opens when sewage is flowing, forcing the flap to open but when the flow ceases the flap closes. This system also prevents a back up of sewage caused by a blockage further down the system from backing up and causing flooding and damage in the house.
