Description

• Budget drain barrier

• Simple to fit

THIS UNIT IS FOR 4 INCH (100mm) PLASTIC OR SALT GLAZED/CLAY PIPEWORK.
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.
How does it the mf3 work?
This unit fits into the chanel exit in an inspection chamber to stop back flow or rats entering your drainage system.
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.
How can vermin get into my drains?
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.
Brilliant new device to stop rats gaining access into your drainage system.
Please note; this model is made of a high grade plastic, but a determined rat can, and will, chew through plastic. Although this is very rare, it is possible. If this this concerns you, you might like to consider a more expensive stainless steel model (see below in ‘you may also like’ products).
There are different models for toilets and drains, the model for toilets is above this one on the page.
