Water Filters For Filling larger Tanks

Every Miles A Memory

Expedition Leader
In the thread describing Shortbus Adventures travels, a forum member asked about filling their fresh water tanks on the Camper.

I commented that when filling our 40gallon fresh water tank in our Travel Trailer, we use a dual canister set-up that allows the 1st filter to simply be a sediment filter to catch anything that might clog the pump, and the 2nd filter being a Class 1 style filter that will filter out 99% of the nasties.

While traveling, we're usually filling our tanks from a gas station spigot or an RV park filling station. Most of these are drawing from city water supplies, so it's not that big of a deal, but not wanting to get a stomach virus while on the road, we always use this dual filter set-up to be on the safe side

I looked through my photos and couldnt find any of my personal set-up, but almost any harware store will have these already made up and ready to buy off the shelf.

Remember that these filters are good for a certain amount of gallons, so I keep a piece of masking tape stuck inside the cabinet beside the water inlet and just jot down how many gallons I filled each time so I can have a rough estimate of when I need to change them out with new ones.

When we're traveling fulltime, we keep a backup set incase we run into a really bad batch of water somewhere. The 1st sediment filter is really cheap ($2-5) and I tend to swap those out more frequently than the Class 1 filters that run around $30-45 depending on where you're buying them from.

I also keep a spray bottle of a bleach solution that is about 50-50 bleach to water in the bin that holds all the hoses and connectors. Before we start filling the 40 gallon tank, I squirt a few squirts into the tank. This was a trial by error sort of thing to find the right mixture that allowed a bit of bleach without being able to taste it in the water. Right now, 3 squirts for 40 gallons is about perfect.

Before putting the hoses away, I squirt one squirt into the hose before connecting it back to itself so it's a closed loop and cant get any nasties growing in it. When using the hose again, I run the water through the hose for a few seconds onto the ground to simply wash out the bleach before hooking it up to the filters.

Remember that this 40 gallons of water is used for everything from dish washing to showering to drinking. If we're drinking right from the taps, which we always do, we carry one of the Brita Pitchers and filter the water a 2nd time through that. I know it seems like overkill since the only time I'm usually drinking water is when it's mixed in frozen form with my Scotch or Bourbon, but again, I cant afford to be sick on the road.

Here is a link to a company that has EVERYTHING you'd need to build your own system from the canisters to the filters to everything in-between. We have no affiliation with this company, just sharing a link for others to get an idea of what is out there

Ditto the second pass through a PUR or Brita pitcher; been doing this the past couple years. If nothing else then for the much better/polished taste for drinking and espresso :coffeedrink:

Many of the communities we've traveled through talk about how clean and pure their water is, but WOW does it ever taste like bleach without us doing anything to it.

The Brita we've found will get rid of any taste in the water and leave you with good tasting water 99.99% of the time. If the Brita cant filter it after everything else we've already done to it, we wont drink it...LOL
 
You have developed a very good method for taking care of your potable water supplies and the extra care taken using bleach on the fittings is something not everybody thinks about, but should...

Another important point is to shop for a Purifier if you want micro-organisms removed. There is a subtle yet vitally important difference between a water filter and a water purifier. The EPA regulates the usage of the word purifier when advertising a water cleansing product. Purifiers MUST be able to successfully remove the most common bugs - if they don't they can only be called a filter.

Your rig appears to meet the criteria for a purifier in that you say it IS designed to remove the little buggers and not just sediment, etc. General Ecology makes portable and stationary Purifiers and I have the portable unit. I'm investigating getting a similiar setup to yours for my trailer - even though I carry enough water to not need refills often.

Overland Journal did a great review of the most common personal purifier/filter units and it's a very informative read. I don't remember the issue, but it seems like it was maybe 2-3 issues back??

Thanks for sharing your technique. As we all know, water is ever increasingly becoming a commodity that we can no longer take for granted - even when traveling in the USA.

Great bit of info 109Pretender. I couldnt agree more and is why I tried to clairfy that we get our water out of spigots that are 99.9999% coming from city water systems that are clean to begin with.

I carry around a little pump that I can hook to a drill motor to suck water out of a lake, puddle or systern if the need arises, but in 4 years of travel, we never had to take it out of the package it came in.

We've yet to travel out of the country, other than Baja and every town we passed through had water outlets that sell purified water where they could run a long hose right out the front door and fill our tanks.

Again, we still used the Brita when using this water, even though it was certified safe to drink, but I'd rather not get sick in another country

I use a pair of these cheap inline filters...

I've been using a pair of these cheap in-line filters for years without problems...

I use one in the water line when filling, then have the second installed in the line from the tank to the pump... all water gets filtered twice through a activated charcoal bed and fiber filter inside the cartrige.
Just swap them out once a year...

Pat, I should have showed you my setup in the Bethany back in August:)

Prybar, how hard are these to swap out with them being inline filters?

With the cartridge style I have, you simply have to have the water shut off, then unscrew the cannister and drop in new filters. I also like to have the clear cannisters so I can see if there is any debris in there floating around or if the filter itself looks any different due to rust in the water

I would have loved to see the set-up in the Bethany, it's such a unique camper!

Reverse Osmosis is really the only way to go. You're not going to filter Giardia and Cryptosporidium, E. Coli & other 'nasties' with a regular media filter.

reverse osmosis isn't required to remove those - the filtering down to under .3 microns will remove bacterial and .01 micron wil remove viruses

(see backflushable Sawyer filters guaranteed to 1 million gallons)

or you can just remove downt othe fine sediment and then treat with a chemical or UV. UV sterilization is probably the easiest.

if you look at the link I posted above of the Super Sterasyl filter elements then you will see that they filter down to .9 microns so they bacteriologically safe. Since they are ceramic they can be cleaned and reused several times.

Thanks for starting this share thread EMAM,
Quite inspired me to join in.

Preparing for our West Africa trip in 2003 with a 4x4 motorhome I resolved that we’d only put safe water into our 200l stainless tank.
Mainly because it is impossible to access and has no maintenance openings.

But I didn’t want the fill up to take too long. At the time in Europe the reverse osmosis and ceramic systems that guaranteed removal of Giardaia, Cryptosporidium, E. Coli etc. (for private use) just weren’t capable of filtering 200 litres in 30 minutes, which is what I had set.

After this time the person whose water we’re drawing would start to get agitated.

So I resolved that rather than filtering them out, we’d just have to put up with drinking dead bodies.
I installed in line:
Optional 12 volt submersible pump at the end of the intake hose.
12 volt Shurflo diaphragm pump with small intake filter.
4 clear filter bodies from a hardware store
A 12 volt 35 watt uv lamp Glass sleeved a stainless outer casing.

With this set up the shurflo acted as a flow restrictor when we connected to taps, and we also were able to draw from 4 metres below ground in a well.

In the filter bodies went:
A 10 micron sieve
2x active carbon filters (for the Brita effect)
A 1 micron cloth filter.

I also carried a cartridge in case the water had a high iron content; the WHO water info mentioned it for central Africa. Never used it.

Once a month we treated the tank with Arvipur silver based product just to stop the corpses rotting. Remember chlorine makes stainless steel brittle.

This system worked perfectly, and my wife found the taste acceptable too (she’s very particular with drinking water).
The only problem we had was in Dakhla where we filled up with brackish water, which ruined the three non-washable cartridges. I carried spares of course.
Total cost to replace a set of filters: 4 Euros!

Initial investment: 400 Euros, the lamp guarantees a 100% kill rate up to 20 litres/minute for clear water.

When I sold the truck I stripped it out, and it’s going into the next one.
Might invest in a desalinator one day.

Happy trails

Easy to change....

Prybar, how hard are these to swap out with them being inline filters

They are real easy... just garden hose connectors on both ends. No tools required. I put one in the pump line in the camper so the water picked up from my carry jug is filtered before it gets sent to the sink or rear outlet.

The second one is in the food grade fill hose I carry to fill the jugs at home or on the road... just hook up to the typical hose bib, and the filter is screwed onto the end of that hose... I use a short piece of hose mounted to the end of the filter to make filling the jugs less of a back breaker.

Your rig sounds great too... just wanted to through out a less expensive option for those on a budget.:ylsmoke:
