The Vetus FTR330/32 Water Strainer used to have a connection kit (Vetus CONN330) so that two FTR330/32's could be connected, doubling the capacity. Incorporating ball valves, this system could be used in such a way that each filter could be cleaned separately with the engine running. Unfortunately, the CONN330 Connection Kit has been discontinued by Vetus. Below is a diagram taken from an old Vetus catalogue which might help you build such a system using materials obtained from your local hardware store. We assume no responsibility if it doesn't work.
