What Is A Weighted Suction Dome? The Weighted Suction Dome Range was developed for customers who have a new or existing pond but want the same great benefits that a bottom drain gives you, without having to rebuild your pond. Weighted Suction Domes are a great device and once connected will greatly improve the water circulation around any pond. This improved water circulation helps remove suspended particles and debris from the bottom of your pond, resulting in reduced maintenance. No digging or putting a hole in the centre of your pond liner is necessary. Just place directly into the lowest part of your pond. A Weighted Suction Dome works in the same great way a Sump Drain does, pulling debris and solids directly from the bottom of your pond straight into your filter system. The Weighted Suction Dome range are all easy to clean and service and are all fitted with a Base Plate set to the correct height to give maximum draw across the bottom of the pond. So even if the bottom of your pond is not completely level there are no worries in restriction of flow. What Comes With Your Weighted Suction Dome Kit? Your Weighted Suction Dome is supplied with a fitting bag that will have all the necessary parts to either work with a gravity or pump fed system. Attachments for fitting to ridgid pipe of 56mm/2” or 43mm/1.5”.
