How often should I change my filter elements?

Our filter cartridges are rated to process 2000 gallons of water. For the occasional camper, annual replacement is fine. For the frequent weekender, we recommend replacing the cartridges twice each year. For the full timer, every two to three months.

Is the system made to connect with standard size water hoses?

Yes! Our systems are designed for use with standard size RV water connecting hoses.

What replacement cartridges does the system take?

The filter elements in all are systems are standard size 2.5 inch x 10 inch cartridges.

In our original two canister system, the first stage is our 5 micron sediment filter. The second stage is our 0.5 micron carbon block filter. Our Clearsource replacement filter twin pack has what you need. Its available here on our website, and on Amazon.

In our three canister Ultra ™ system, the first stage is our 5.0 micron sediment filter with scale and rust inhibiting technology. The second stage is our 0.5 micron carbon block filter. The third stage is our 0.2 micron (absolute rating) filter. “Absolute rating” means each pore is the rated size or smaller. Our Clearsource Ultra system replacement filter pack has what you need. Its available here on our website, and on Amazon.
What are the flow ratings?

That’s an important question. We use oversize, high flow filter canisters for maximum water flow. We lab tested our two canister system at a low 40 PSI of static pressure, and measured an outstanding 6 GPM – 6.5 gallons per minute of water flow. Under the same conditions, our Ultra system produces approximately 4.5 gallons of flow.

Do the filters come with your systems?

Yes! Our systems come fully assembled, and ready to go right out of the box.

Why do you say the Clearsource filter system will give me better water? What does that mean?

Contaminants range in size. Silt and sediment range in size from 50 to 150 microns. Other contaminants are much smaller. Giardia and cryptosporidium can be as small as 0.5 micron. Bacteria range in size from 0.2 to 10 microns, with cholera, e. coli. and salmonella in the 0.2 – 0.5 micron range.

Filters are rated by the size of their pores. A filter with a rating of 100 microns might reduce the sediment in your water, but it will leave in harmful chemicals, bacteria and cysts. Many small in-line filters, typically blue and about the size of a cucumber, are rated at 100 microns – or not at all.

A 5.0 micron sediment filter will do a great job on silt and sediment. A 0.5 micron filter treats Giardia, cryptosporidium and many bacteria, but would be prone to clogging unless paired with a sediment filter in a two-canister setup.

In our two-canister system, in the first canister, we install a filter element specifically designed to reduce silt and sediment. Its rated at 5 microns, and is perfect for the task. The second element in our system is a .5 micron activated coconut shell carbon filter. It’s made to the highest standards in the industry. It reduces or eliminates contaminants that other filters miss, like chemicals, volatile organic compounds, pesticides, cysts, and more. Its activated coconut shell carbon technology makes your water taste terrific.

In our three-canister Ultra ™ system, the add a 0.2 micron filter in the third stage to block cholera, e. coli, salmonella and similarly sized bacteria. We also install our 5.0 micron sediment filter with rust and scale inhibiting technologies in the first stage.

Why do you say the Clearsource Filter System provides better water flow? Don’t you mean better water pressure? And better than what?

"Water pressure" is the term people use to describe the force of the water coming out of a shower head, a faucet, a hose, or any other plumbing device. What folks are really describing, however, is water flow.

Water flow is the amount of water coming out of the fixture. Water pressure is measured when the system is closed – when all the fixtures are off. High water flow makes for a great shower, quickly rinses the soap off your hands when you wash them, and blasts the food off your dishes. Most important, high water flow lets you and your family do all those things at the same time without any loss of what folks typically call “water pressure.”

Water flow is determined by the size of the medium through which it is passing. That’s why firemen use fire hoses instead of garden hoses to fight fires. Small, disposable in-line filters (“blue cucumbers”) have narrow water passages that restrict water flow. Our oversize filter canisters deliver noticeably better water flow, especially under heavy demand.

How do I hook it up?

Attach a hose from the hose bib at your campsite to the inlet side of the filter (on the left as you face the system. The inlet fitting is female, and rotates.) Attach a second hose to the outlet fitting on the right side of the system and connect it to your RV's fresh water connection.

Should I flush my system before using it?

Yes, and after every filter change. While setting up, just leave your outlet hose disconnected from your rig, turn on the water, and let it run for a minute or so. That will flush the filters.

I’m not a full-timer. What do I do between trips?

Great question. If you will be leaving again in a week or two, nothing. If you will not be using your system for a month or more, unscrew the canisters, empty the water and remove the elements to dry storage. They are perfectly happy drying out and getting wet again!

Where may I obtain replacement filter cartridges?

The filter elements in systems are all standard size 2.5-inch x 10-inch cartridges. Our Clearsource replacement filter twin pack and Clearsource Ultra ™ system replacement filter pack have what you need. You may find them here on our website, and on Amazon.

Should I use a pressure regulator with your system?

Yes! Your RV is a home on wheels. Everything in it is designed with weight in mind, including the plumbing. That means the plumbing system is less robust than the plumbing system in your home.

Most RV manufacturers recommend you limit the water pressure with a pressure regulator to between 40 and 60 psi. Restricting the pressure makes maximizing water flow that much more important. The best way to do that is to buy a high-quality pressure regulator, set it at a safe setting, and make sure everything else in the system gives maximum flow.

Does the Clearsource filter system treat lead?

Our system will reduce, but not eliminate, lead. If lead is of concern, we offer a filter cartridge specially engineered, and rated, to treat it. Contact us at info@clearsourcerv.com.

Does the Clearsource filter system treat rust?

If you live or visit in a campground with a rust problem, we sell our rust inhibiting filter cartridge with RustStop ™ technology here on our website, and on Amazon (search for “Clearsource Rust Inhibiting Filter Cartridge.”) It performs the same sediment blocking function as our sediment cartridge, and also traps iron particles and rust. It may be used in place of the sediment filter in our two canister system. It comes standard on our Ultra system.

Does the Clearsource filter system treat sulfur smell?

It does not. Sulfur smell is not effectively treated with filtration. 

What are the dimensions of the systems?

Two canister external system: 15 inches tall x 14 ¼ inches wide x 7 ½ inches deep.
Three canister external system: 15 inches tall x 20 inches wide x 7 ½ inches deep.

I’m worried someone might steal it. Can I lock it up?

Yes. Any standard cable lock will work – just wrap it around the center post in the front of the system, or around the connecting pipe between the two canisters. Attach the other end to something immovable.

I have other questions. Can you help?

Yes! Please contact us at info@clearsourcerv.com. We will get right back to you.
