Water filter plumbing systems

I have a 2016 Mini Lite with the water filter system. The documents state that the system filters all incoming water. Does it filter water entering the water tank and not leaving the tank? Does it filter water entering via the city water connection? How are the water tank plumbing system and the city water plumbing system connected? Thanks.

Filter doesn't typically filter water going into the FW tank. It will filter water coming from the tank.

Here's a generic plumbing pic. Your's may or may not match in all respects. (My mini lite has the 3 way valve on the pump suction. My Roo 19 had the 2 separate valves.)

Water from your storage tank runs through the water pump and into your water system. When you hook up to city water, the water goes directly into the water system. There is a check valve in the water system so that city water cannot back flow into the water tank.

Your water filter should be installed right after where the water from the tank and the water from the city come together and prior to where you use it.

Hope my response made sense, It seems as though no one has been able to acquire a generic water piping diagram from Forest River. If one was available, these type of questions wouldn't be constantly asked.

If you want a plumbing diagram, you will pretty much have to make one yourself.

Thanks all for the quick replies. Diagram seems to clarify things. One last question. Does anyone pre-filter the water going into the FW tank on a system with a factory internal filtration system?
Thanks.

I took removed my filter and replaced it with a coupling. I've read too many posts about these internal filters cracking and putting water everywhere. So now I use the Cameco in-line filter that goes right on the hose.

The advantage of this is that I can use the in-hose filter to filter any water I put in my FW tank.

We do, whenever filling the fresh water tank or when using city water at a site. It's cheap insurance.

In our 2014 Solaire 199x I removed the in-house and went with external like rockfordroo did. This way I fill my FW tank using filtered water. Now with the my new 2017 Surveyor 251rks I do the same and it works great. Easy and no worries about leaks in compartments that maybe hard to reach like in my 199x was. Good Luck and Happy Camping!!

I have seen a number of people who pulled the provided filter, replacing it with a connector. THEN they reconfigured the filter so that it was outside the trailer - either between the CG water supply or pushing home city water thru it into the FWT. One guy put a hole in his bumper and used that as a mount for the filter. The provided filter has the advantage of using replaceable media of the type you want - cheap grit up thru more expensive multi stage carbon... Going with something like the Camco filter means you throw the whole thing out probably once a year.

We use pre filter and the filter on the trailer. We just feel better knowing it's there.
