Downpipe Guard

Products to Prevent Blockages


Rainwater Pipe

It is quite common for roof moss, leaves and twigs to wash down the roof into the gutter and then into the rainwater downpipe where they can cause a blockage. Most downpipes have angles which are known problem areas for blockages - worst case scenerio is the block occuring in the underground pipes which can cost a small fortune to repair.

We have other pages which address the importance of removing roof moss and also a few pages which cover the most popular gutter guards available on the market today.


This page covers the products that can be purchased and installed to prevent the blockages in the downpipes.
In our opinion it is best to address any problems with gutter/pipe blockages upstream so for example if your property suffers from excessive roof moss it would be wise to consider removing it rather then buying traps and filters which will potentially require lots of maintenance.






Downpipe Filter - Prevents Pipe Blockages

The rainwater downpipe Balloon is a simple filter that is inserted into the top of the downpipe to prevent blockages by debris such as roof moss and leaves


This filter is a cost effective and simple to install product that works well however the product does become clogged easily and once this happens the rainwater will not be able to escape the gutter and overflowing is likely.
So in summary this product offers very good protection against expensive to repair blockages but actual maintenance may even increase as the filter will require frequent cleaning.

It is worth noting that this product works very well in preventing expensive underground blockages but it doesnt stop the rainwater downpipe itself from becoming blocked.
