This week I'm working on installing new hoses and water filter for my boat (3M BS1 whole vehicle filter). The current configuration has the filter installed after the manifold for selecting water tanks, but before the t-fitting for the pressure water pump and foot pumps. Each of these pumps supply water to different faucets on each of the three sinks.
Here is a photo of the sink setup (doesn't show the Whale foot pump).
Now to the question... How do I install the filter after the pressure pump, but still have filtered water coming out of the faucets for the foot pumps? Or do I not worry about the pressure water pump (not used much) and just leave the system as is with the water filter before the pressure pump and all three foot pumps?
It's one of these pumps:
