Rigid Pipework and FittingsFor many pond filters the return pipework to the pond will be connected using a connector suitable for rigid pipework. All of our rigid pipework is black in colour so that it can be easily concealed. Algae is also less likely to form on black pipework which means that any equipment that is connected to the pipes will continue to work efficiently, as the flow of water through the pipe will not be obstructed by any algae on the inside of the pipe. If rigid pipework is too restrictive, we also stock 76mm flexible pipework which can be fitted over Oase 75mm connectors |
