Our Rapido Quattro downpipe filter is revolutionary. No need to cut your downpipe in half and take it off the wall. Simply use the hole-saw provided to drill the correct size hole in the downpipe and the tank, and our Rapido Quattro simply fits in! This solution is installed in minutes to downpipes that are 65mm – 90mm. All of the tools required are included in the pack (excluding the drill).
