Nope. inlet at tank -> hose -> double tap -> a bit of hose -> pump (inlet) -> pump (outlet) -> a bit of hose -> double tap ->hose -> outlet at tank. I can just disconnect the 2 double taps and I can just remove my pump completely from the system. Good for maintenance and emergencies. I do that to all my equipment, even when they are chained along each other, so I can remove and replace any part as and when I like,
bad photo as all my double taps seems to be hiding, haha.
