The FloPlast Black Square Downpipe is designed for efficient rainwater drainage in residential and commercial buildings. Made from durable plastic, it offers a long-lasting, weather-resistant solution for directing water away from gutters. Its black finish is compatible with most building exteriors and it is ideal for use with square guttering systems. This 65mm downpipe is available in 2.5m, 4m and 5.5m lengths. Square downpipe is usually used in conjunction with square and sometimes ogee gutter systems. 2.5m lengths are usually sufficient for rainwater pipe drops on single storey buildings, while 4m and 5.5m lengths are generally used for buildings of two storeys and above. Rainwater pipes are always a pushfit joint; never use silicon or solvent weld on these systems as there might be a requirement to take them apart for cleaning or unblocking at some point in the future.
