How to Store an In-Line Water Filter When Not in Use

How Often Should I Change My RV Water Filter?

To store an in-line water filter when not in use, drain it first and then put it into a zip-top bag (to use TSA’s vernacular), and throw it in the fridge. Be careful not to hit the eggs; that could get messy.

After you break camp, let the excess water drain out. Then, use the plastic caps that came with the filter to close off both ends to seal it up. If you can’t refrigerate the filter, keep it in the dark to prevent bacteria growth. Some will use a three-foot water hose connecting to both ends of the filter.

One idea that’s been floating around the RV Community for decades is painting your RV inline water filter. Different versions claim that one color is better because it blocks sun exposure.

There’s not enough evidence to support this idea, but those that use fluorescent paint or tape make it easier to avoid tripping hazards.

How to Store a Two-Stage Water Filter When Not in Use

Storing a two-stage water filter when not in use is the same as an inline RV water filter. Place it in a zip-top bag and refrigerate. Putting an RV water filter in the freezer will destroy it. As the water turns into ice, the crystals rip the paper-like material. Ice also damages the integrity of the carbon material of inline filters, so avoid the freezer.

How to Store Your Fresh Water Hose When Not in Use

When not in use, storing your freshwater hose should be more complicated than coiling it up and tossing it in your exterior bay. The difference between an RV water hose and a garden hose has to do with the construction of the water lines. A garden hose’s purpose is for outdoor use only and has a liner that prevents leaks.

RV water hoses have a special lining for human consumption, bathing, and other uses. The liner prevents ground pesticides and other chemicals from leaching through the hose. That’s why many prefer to place the inline RV water filter on the campground water hookup; only clean water flows through the hose.

Here are some travel trailer water hose storage ideas to keep it safe from contamination:

  • As you coil it on one end, leave the other end loose on a clean surface (like an RV jack pad) to thoroughly drain the hose.
  • Rinse off the brass ends and screw on RV water hose caps or screw the male end to the female end of the hose. It also prevents dirt, bugs, or other things from getting inside.
  • Store your freshwater hose in a sealable storage bin to prevent water seepage from ruining your gear or RV. 

RV water hoses last an average of 5-10 years. When running through your preventive maintenance checklist, it’s a good idea to run water through it at home, checking for leaks along the line and the brass fittings.

Leaks in the brass connections may be simple by replacing the rubber gasket. Also, make sure the exterior is clean and contaminant growth particles aren’t coming from the hose itself (use an inline water filter on the spigot to prevent anything from the water pipes).

Some use a highly diluted solution of bleach and water (about a ½ teaspoon per 5 gallons) to soak and disinfect their water hose. It may seem like a weak mixture, but you don’t want the bleach to destroy the hose’s liner. When in doubt, RV water hoses cost around $20 to replace. When it comes to drinking water, your mantra should be “new is better than damaged.”

How Long Will an RV Water Filter Last?

The time length an RV water filter will last ranges from three to six months. It depends on the amount of usage, storage conditions, and other factors. For example, full-timers will run through a value brand inline RV water filter within three months, while a weekender can stretch out the same filter up to six months using the proper storage techniques.

3-stage RV water filter system cartridges may last a little longer if you clean them correctly. These filters are fragile, so using the wrong cleaner or the wrong dilution ratio can damage them.

Do RV Water Filters Remove Bacteria?

The best RV water filters don’t remove bacteria. Water filters remove heavy metals, chemicals, dirt, sand, and other contaminants.

Government agencies that monitor water quality have standards that utility companies must adhere to for microorganism counts. They use chemical and other treatment techniques to minimize those counts.

Natural wells use commercial level filtration systems to reduce bacteria and viral counts.

What’s the Best Way to Ensure My RV Drinking Water is Safe?

The best way to ensure your RV drinking water is safe is to treat your RV’s drinking water with a UV-LED water purifier. Industrial versions have existed for years, but companies like Acuva Technologies (AcuvaTech), have shrunk the technology and made them affordable for home and RV use.

Installing one of their UV-LED Water Purifiers disinfects 99.9999% of all microorganisms in your post-filtered RV water. Off-grid RVers will enjoy the energy efficiency of the LED system, budget-conscious campers will love the long life and affordability.

How Many Uses Can I Get Out of a Filter Cartridge Only Using it on Weekends? (cartridge inside multi-stage filters)

Ideally, weekenders can get six months of use out of their filter cartridge if they correctly follow the RV water filter storage procedures. That’s 26 weekends in six months (52 weeks in a year, divided by two). 

Yet, we don’t live in the vacuum-like conditions of a laboratory. Review apps and trip planners like RV Trip Wizard and The Dyrt do a great job giving you the real story behind every campground; you never know what your campsite’s water conditions are until you open the water hookup. 

We recommend changing your multi-stage RV water filter cartridges, as a weekender, around the five-month mark to be safe. You want to protect your RV’s plumbing from contamination as best possible. The new filter cartridges for $20-$30 are a lot cheaper than replacing the damaged PEX plumbing throughout your RV.
