Stop leaves blocking drains with this downpipe leaf filter.

Blocked gutters can lead to water overflow that can cause damp problems or damage your home walls. Unfortunately, unblocking gutters is a task that is often overlooked until it rains heavily. By fitting a leaf separator filter, you can help avoid any potential damage a blockage may cause and ensure the longevity of your property.
