Flexible Connections Between Above Ground Water Tank and Piping
Flexible Connections Between Above Ground Water Tank and Piping
(OP)
When connecting piping (above ground) between fire pump suction and and an above ground water storage tank, it is required to have a flexible connection. I have yet to find a flexible connection pipe that is listed for fire protection systems. The size would be 8" or 10". Does anyone know of a listed flexible connection for this situation?

As per NFPA-20 clasue 4.14.6.5 - strain relief (like flexible connector) is required only where the pump and its suction supply are on separate foundations with rigid interconnecting pipe. Therefore, it is not always required to have a flexible connector.
BTW, i also used metraflex before in my previous project.
Hope it helps,
