Questions arise on how to filter the potable water carried by our vessels. Warren Updike, Warr De Mar, #62 writes:

On our boat the Jabsco water pump has a plastic housing on the input side with a small screen inside. This is not a filter, per se, as it is simply intended to protect the pump from particles large enough to damage the impeller. This pump is located under the port settee where one water tank is located in our early version of the C-320.

I installed a separate filter between the pump and the tanks. I used a Pentek 158002 Blue/Black 3/8" Filter Housing with a CBC-5 carbon black water filter. This filter is the same size as the Culligan C-2 very popular in the RV trade. The carbon black filter is the key here, use no other. The result is that the water from the taps is very drinkable with virtually no "tank" taste. Even if you add chlorine to your water tanks this filter will remove the chlorine taste. I bought all this from www.filtersfast.com. Be sure to buy the separate mounting bracket and filter wrench too.

I found that the CBC-5 Carbon Black filter was too restrictive for my old/original pump. The line pressure was reduced to an unacceptable level. I went back to the C-2 filter. Perhaps, newer or stronger pump would handle the pressure issue better than did mine. PS - I have since replace my pump with a new one. Warren

I use an rv filter that screws onto the hose when filling the tanks.
I also use an RV filter on my hose when I fill the tank. I addition I installed a Brita faucet filter on the galley faucet so I can filter drinking water, and it has a by-pass if you want full flow. I find the reduced flow with the filter on actually helps me conserve water on longer cruises.
