Green Monster UK supply pest control products for the exclusion and treatment of public health pests.

At Green Monster UK the health of our planet is of utmost concern – We strive to be Green – just like our monster!

Both energy and carbon efficiency are at the heart and forefront of every manufacturing and logistical decision we make and we are committed to only working alongside organisations that share our dedication to sustaining our planet.


Green Monster drain valves are made from high grade (304) anti-corrosion stainless steel. They are suitable for installation within drainage/sewer systems made of PVC, clay and cast iron pipework.

Once correctly fitted, the curved flap of the valve will open to allow free flow of water and waste materials, shutting itself once flow has stopped.

The curved flap sits perfectly within the pipework and prevents any rats from bypassing the valve, therefore gaining entry into your property via the drainage system.

The valve stays in-situ within the system by means of two flexi brackets that cause mechanical compression of the side walls.

We also suggest the use of our bespoke installation pole.

The valve can be easily opened so that the aperture is a few millimeters larger than the pipe to be fitted in. Once the bespoke installation pole is attached, the valve can be inserted into the system and by twisting the installation pole in a clockwise direction it will compress the unit to become the perfect size for the branchwork and is an ideal problem solver when carrying out installation into deeper chambers.

You need to have an accessible inspection chamber on your property, where you can readily access your drainage system.

Follow these steps to install your Green Monster UK LTD Drain Valve.

  1. Find an accessible inspection chamber
  2. Open the lid of the chamber and inspect the branches within. Note: You may have a number of separate branches
  3. Flush any toilets in the property to identify where the waste water runs and check the direction of flow
  4. Push the drain valve into the main outflow branch
  5. Secure into position using the restraining wire by attaching this to the side of the inspection chamber, alternatively use the stop bolt provided.

It is worth noting that although an inspection chamber on your property will be taking your drainage, it could also be collecting drainage from adjoining properties. In this case you will see branches taking your waste water joining into the main run of the chamber which collects the waste.

Although installing your Drain valve into the main outflow branch will protect all other branches within the system, this may be against the regulations of the local water authority and the best course of action would be to install the valve into your outgoing branch only.
