The sump is supplied with a flange ring, which can be screwed to its top lip. If the pond is liner-based, the liner should be sandwiched between the flange ring and the sump lip, and adhered with a suitable sealant, creating a water-tight seal. If the pond is concrete the flange ring is not required. The top of the sump should be set level with the pond’s final rendered layer.A gap of usually around 2 to 5cm is set between the top of the sump and the dome, and should stop smaller pond fish from entering the filter system.
As the pipe-work used in the construction of a gravity fed filter runs under the pond and is usually set in concrete, bottom drains should be considered at the outset of pond planning, and installed as the pond is constructed.Bottom drain set ups are a much more efficient than having a pump situated in the pond, pushing water to a filter. Bottom drains can handle larger solids than most types of pond pumps, and are far less likely to block or become hampered by debris.
A pond can be built with multiple bottom drains along the floor, leaving no areas in the pond for sludge to accumulate. Also, a submerged pond pump requires hose connecting to the filter, and a power cable, both of which have to be concealed to improve the pond’s aesthetics.
To obtain a maximum flow-rate and reduce the build up of debris in the pipe-work connecting the bottom drain to the filter, the pipes should run as directly as possible, and any bends should have a large curved radius, as apposed to a sharp 90° elbow. It is recommended that the pipe-work between the bottom drain and the filter should be Solvent Weld Pressure pipe.
