Due to a recent freeze while we were away, the filtration system in our bay got destroyed...Looking to use an external one now and probably under sink.As full timers moving to unknown water systems all the time, what are your recommendations?

I have a sediment and a carbon filter. I test the faucet water before connecting the RV. If OK the tank will be full when we leave.

We moved ours indoors to under our sink as well due to getting to cold in our rig's wet bay. Don't find a need to filter shower, toilet, or dish water although we have an external filter we could hook up, under most circumstances we bring city water from home and use our FW pump. We get our dual filtration system/filters from Lowes, Home Depot, good variety on Amazon if you don't want to hassle with big box stores. Fittings can be had from locations above to easily integrate into plumbing under sink. After all that, we drink bottled water and use filtered water primarily for cooking.

If you get a whole house filtration system, I recommend getting a sediment filter only. Do not get a filter that removes chlorine. The chlorine in municipal water will help to keep your supply lines and tanks sanitized.Reserve the chlorine removal and final polishing for just the sink. In our case we have just settled on using a Brita.

Good point Jim. Our charcoal filter is not used to fill the tank but is used for hookups. This setup works for us since we often use tank water which keeps the rig sanitized.I don't fill the tank if the water is questionable and carry water bottles as backup.

You need to figure out what you want to filter and what your budget is. The best are reveres osmosis filtration systems and are expensive.The blue Camco in-line filters are 20 micron and won't filter out any nasties. They're for removing some odd taste at best.Our Walmart recently stocked a filter that works like the Camco but is a 5 micron filter. That's good, but if you're worried about nasties then you really need something like a 0.5 micron filter.So it depends on the quality of your water source and what you're trying to remove/

What are you using for external water filtration?
