Mcalpine ARB-1 Anti Cross-Flow and Rodent Barrier Valve, Black

Product Information

Doors should fit tightly, the distance between the bottom of the door and the threshold not exceeding 1/4 inch (0.6 cm). In some instances, it is possible to build up the threshold rather than modify the door. They are designed to be effective against the consequences to your home of drain flooding after heavy rainfall or burst water mains. Tighter UK restrictions on rodenticides use (CRRU) - targeted proofing provides compliance with CRRU regulations, reducing environmental impact on UK wildlife by preventing rodent ingress and therefore reducing the need to use rodenticide.

Properly applied flashing extends to within 1/8 inch (0.3 cm) of the edge of the door at the sides and bottom. Close the gap at the top or sides of roll-up doors with conveyor belt material shaped to fit into the side channel frames and mounted on the top door jamb. Bent bottom rails on doors should be straightened. Concrete dam-age due to inadequate reinforcement or poor placement practices should be repaired or the concrete replaced. A metal or pipe threshold is sometimes preferable or required. Maintaining a clean, 3-foot-wide (1-m) weed-free area around building foundations, concrete slabs, and footings often discourages rodents from burrowing as well as eliminates a food source and attractive harborage. Where erosion of bare soil is likely, this buffer can be maintained by regular, close mowing of vegetation or by installing heavy gravel. To discourage burrowing, install a strip of 1-inch-di-ameter (2.5-cm) or larger gravel laid in a band at least 2 feet (60 cm) wide and 1/2 foot (15 cm) deep. 1/4″ meshRats are great at climbing and swimming, and can hold their breath for long enough that it allows them to travel from one location to another through sewage pipes and drains. Whats The Advantage Of Using A Rat Flap? Since the 1950’s drainage systems have been much less isolated from the main street sewer and this has allowed rats more access into peoples drainage systems. Damaged or unmaintained storm drains and sewer pipes easily allow vermin access into the main drainage systems. From here they can enter your home by travelling through sewers, up pipes and exiting from the foul air outlet at roof level or swimming through the water contained in your toilet system. The MultiFlap ensures you’re protected by keeping them in the sewers where the authorities can deal with them. Firstly, it is very important to note that rodent mesh is not the same as insect mesh. These meshes are not interchangeable. Rodent mesh is relatively much tougher. Rat mesh and mouse mesh is also more expensive because it contains more metal. Conversely, insect mesh is cheaper, lighter, is woven with fine wires and has much smaller holes. Rats and mice will gnaw through insect mesh with ease. Rat Mesh The MultiFlap is a one-way non-return valve that fits easily to the exit pipe from your house to the street sewer. This means waste still goes out from your house, but immediately after the waste water has gone, the flap closes to prevent anything nasty coming up the wrong way. The prevention method and the ease with which the MultiFlap can be installed makes these products truly unique.

All equipment such as large refrigerators, freezers, counters, dishwashers, and sanitizers should be raised and easily movable, enabling cleaning underneath and behind them. Insulated walls and closed areas should be tightly closed off to avoid use as harborage. Openings are commonly seen in new stainless-steel work counters in supports under the work surface, or in areas provided for drains. Drains should be easy to clean but should have rodent-proof covers. The valves do not require any maintenance as they are made using 316L grade stainless steel, and once fitted you can rest assured it will do its job for up to 20 or more years.Figure 9. Patching small holes with copper gauze and a fast-drying patching compound (left), and 1/4-inch hardware cloth for larger holes (right). Proper storage and disposal of house-hold garbage and dead animals is a very important part of rat control. Bulk dumpsters are often left with the tops open, or the tops are badly bent, allowing rodent entry. Constant vigilance and calls to the refuse company should correct these situations. Seal bulk trash compactors from rodents. Spilled refuse and juices from crushed contents often create rodent problems under and behind compactors and bulk dumpsters. Clean these areas of-ten and install rodent screening in container drains. Rats can access buildings via the drains and drainage valves or rat flaps can be employed to combat this issue Rentokil’s Flexi Armour range provides sustainable rodent proofing solutions to help protect buildings internally and externally. By utilising hard wearing, flexible Kevlar and knitted steel mesh, Flexi Armour provides impenetrable barriers that prevent rats and mice entering your premises. An integral part of the Flexi Armour Range is the rodent door proofing solutions we offer for both pedestrian doors and commercial roller shutter doors. These door proofing options offer a sustainable approach to Integrated Pest Management by restricting rodent intrusions into your business. Flexi Armour Expansion Joint Proofing– this resilient yet flexible proofing solution eliminates the gaps in expansion joints on floors and walls in larger premises, preventing rodents chewing through and entering the voids.

Use only metal window screening materials where windows or doors are accessible to rodents. Avoid unnecessary ledges outside windows. When necessary, screen ventilation openings and windows with woven/welded galvanized hardware cloth. Such screening is critical in commercial and farm buildings and where high rodent pressures in residential areas are found. For large openings or where the screen may be subject to abuse, add crossbars to support the hardware cloth. If the opening is an access route, install the screen on a hinged frame. Rodent-Proof Construction | Rodent Entry Points | Rodent Exclusion Methods | Rodent-Proof Construction | Rodent-Proof Resources | ICWDM | Wildlife Species Information There are many points of potential entry into a building for a rodent. One of the reasons businesses develop pest problems is because they don’t fully rodent-proof their premises’. Proofing is always the first line of defense against rodent infestations. The Flexi Armour rodent proofing range of door seals provides effective proofing measures, to help prevent the entry of rats and mice and reduce the risk of a rodent infestation developing on your premises.We provide a variety of effective proofing solutions against rodent infestations to help protect every aspect of your business: Please note this unit is NOT suitable for an outlet pipe into manhole, it will only be suitable for the pipe that exits manhole to sewer, therefore you need to locate last chamber before sewer.

Audit Compliance– proofing expansion joint gaps supports your audit compliance by proactively minimising the risks associated with internal mouse and rat activity. This in turn reduces the need to use rodenticide within your facility to control infestationsas you arerestricting rodent access. Minimal Disruption - proofing is expertly and swiftly installed by professional Rentokil technicians, minimising any impact on your business. The choice between concrete and wire mesh depends on the expected life of the structure. Though wire mesh costs considerably less than concrete, its usefulness generally lasts only 5 to 10 years.Rats typically burrow and nest under feed bunks that are placed directly on the ground or near ground level. Properly designed concrete bunks that sit tightly on a concrete base eliminate rodent habitat. Though cattle traffic may discourage burrowing under the concrete slab, a foundation may be needed to prevent burrowing around the sides of the slab that do not receive heavy cattle use. Concrete slabs on which feed bins are placed should have foundations extending 36 inches (91 cm) into the soil at the outer edge to prevent rats from burrowing under the slab. Installing heavy gravel and maintaining a clean, weed-free zone around the perimeter of the slab will also discourage rat burrowing and permit easier detection of rat activity. Proofing door gaps - restricts rodent activity and therefore help reduce rodenticide usage, as infestations are reduced.
