This is impossible to put together. etrailer sent replacement parts and they turned out to be the same as what came in the box. Bottom line, they do not fit snugly at all. Stick them in place and they fall right out. You would think threaded pieces would fit but they are so loose they fall out. Add more plumbers tape and I get the same results only a little slower. I'll be sending this filter and the two replacement filters and all these duplicate pieces back. I want my $$ back.



by:

The filter and associated stand are quality constructed and work well out of the box. Thanks for a pleasant transaction, speedy (and free) shipping!



by:

All my parts arrived sooner than expected. The filter and trailer coupler are perfect. The wiring instructions for the Breakaway switch are a bit confusing, but a little research sorted it all out.



by:

Works great. Very easy to install. If only crawling into the pump locations was as easy.



by:

Bought this filter as a replacement to an inline filter, believing it would do a better filtering job with some water suppliers in Florida. Once a year cartridge replacement seems adequate, but make sure you can find the canister wrenchwhen needed as the attachment can be tight.



by:

The experience of reviewing the product online and getting what you paid for that works and fits with no modifications or no additional fittings or adapters necessary. Everything you need to review the product with instructions and detailed pictures and videos about the product as if you were literally in the store buying it.



by:

Easy to assemble and install. Bought to remove chlorine smell/taste from water feeding our 5th wheel, didn't do the job. Seems to be a decent filter, just didn't do what we need.



by:

This is the 2nd one that I have ordered the 1st one I ordered back in 2015 the nylon female nut cracked other than that the water filter functioned rather well, easy to hook up and maintain.



by:

ALL PRODUCTS ORDER ARRIVED EARLY AND WAS IN GREAT SHAPE. eTRAILER HAS A GREAT SELECTION OF PRODUCTS MAKES IT EASY TO SHOP JUST AT ONE WEB SITE. WILL USE THEM AGAIN.



by:

Great camping water filter. Good buy



by:

Good , but not good mounting. Otherwise happy.



by:

Easy instructions, easy installation.



by:

Filter leaks no matter how tightly I hook it up. I haven’t thrown it away yet, but probably will when I get ready for next season.

I will have our customer service team reach out to you. The water filter does have a 1 year warranty.



by:

My boyfriend said I did very well when he saw the filter. He said, can you believe we are going to have pure water!



by:

Easy to install. I use it everyday and it has held up well and the water tastes fine.



by:

You know just how important is to us as travelers to get used to good drinking water. With this product it made the experience much simpler.



by:

Awesome product if it does what it's supposed to . Have yet to use, will review after it's been tested.fast service from company



by:

Easy ordering, earlier delivery than expected. Timing was right on. I will be back!



by:

Did not realize UPS delivered the filter to the Post Office. i received an e-mail from UPS stating it would be delivered Thursday however, the Post Office delivered it on Friday. The order was satisfactory.



by:

Great product but will wait till next year to use it, Thanks

  • GPM for the Camco RV and Marine Premium Water Filter w/ Replaceable Cartridge
    The GPM for the Camco RV and Marine Premium Water Filter w/ Replaceable Cartridge and Hose Extension, # CAM40631 is dependent on the performance of the pump within your system. This will have minimal, if any, reduction in your current GPM with fresh clean filters. Any reduction in flow is effected by condition of filters. Use the Camco Replacement KDF/Carbon Filter Cartridge for RV and Marine Premium Water Filter, # CAM40621.

  • Can Empire Faucet EM65FR be Used with Water Filter
    The Empire Faucet # EM65FR does not have ability to have a Pur water filter added to it but we do have water filtration systems that was designed for RVs like with the Camco RV and Marine Premium Water Filter # CAM40631. You could install this on your RV and then use the Empire faucet and you'd have filtered water like you are wanting and be able to use this faucet.

  • Can Camco RV and Marine Water Filter be Used to Filter Water in On Board Fresh Water Tank
    I spoke with my contact at Camco regarding the RV and Marine Premium Water Filter # CAM40631 referenced in your question. He stated that you can absolutely use this filter for your specific application. You will have no issue using this to filter the water in your on board fresh water tank via a foot operated pump. The premium spun polypropylene filter will clean the water using 3 media and the replaceable filter cartridge is good for a full camping season. The filter housing, 12 inch...

  • What Is the Micron Rating of the AquaFresh Exterior RV Water Filter Kit
    I did some checking on the AquaFresh Exterior RV Water Filter Kit part # A01-1131VP and the micro rating is 20. The water filter kit reduces chlorine, sediment, and bacterial all while improving the taste and odor of your fresh water supply. The filter will need to be replaced when your water flow deceases as that is a sign that the filter is full. The AquaFresh Exterior RV Water Filter part # A01-1132VP can be used for this. The Camco RV and Marine Premium Water Filter Kit part # CAM40631...

  • Compatible Fitting Sizes For The Camco RV And Marine Premium Water Filter # CAM40631
    The Camco RV and Marine Premium Water Filter, part # CAM40631, uses a standard garden hose connection of 1/2" inner diameter and 1" fitting. If the 1/2" input and output connection types you have are male then you won't need any adapters to connect this filter.

  • Replaceable Single Cartridge In Line Water Filter For Connecting to 3/4 Inch Water Hose Fittings
    The Camco RV and Marine Premium Water Filter # CAM40631 includes the connections for attaching to your 3/4" water hoses. This is ideal for outdoor use with the Stand # CAM40772 to keep it upright and off the ground. The AquaFresh Exterior Water Filter System # AF67FR you found uses 1/2" fittings which are more commonly found on the plumbing inside the camper. This is exterior rated as it is often placed inside the storage area of a 5th wheel where it is not always climate controlled....

  • What Hose Fittings Does the Camco RV and Marine Premium Filter Use
    The Camco RV and Marine Premium Water Filter, part # CAM40631, uses a standard garden hose connection of 1/2" inner diameter and 1" fitting. We have a hose here that is not a direct replacement, but is confirmed to work with the benefit of additional hose length. It's the Camco RV Drinking Water Hose, part # CAM22763. It's 4' long and has the exact fittings required by the Camco Filter. I've linked to a video review of this hose for you to look at. There are two adapters included with...

  • How Is Debris In Water Trapped By Water Regulator For RVs
    A water regulator like part # A01-1122VP has a small filter that catches most of the debris you may have in the water. I have attached a photo of the regulator that shows the small screen. After the water pressure is reduced you can use the filter like part # CAM40631 that will clean up the balance of debris like aluminum, bacteria, bad taste, cadmium, chlorine, fungus, heavy metals, hydrogen sulfide, iron, lead, mercury, mold, odor, cloudiness, and sediment.

  • Can I Use Camco RV Water Filter To Filter Hot Water That Smells Bad
    The Camco RV and Marine Premium Water Filter w/ Replaceable Cartridge and Hose Extension part # CAM40631 is meant to be used on the main water line on the exterior of the trailer. I contacted Camco and there would not be a way to connect a hot water line to the filter because it is designed to be hooked to a hose. It is also not made to filter hot water. Currently all of the water filters that we carry are exterior filters. It sounds like once the water gets into your water heater it...

  • Replacing KW1 Filter With Camco System
    We do not have a KW1-style replacement water filter, but I may have a better solution for you. The KW1 Style filter is unique to some Forest River RV's and as such may not be as easy to find as more common styles. If it were me, I would replace the filter houseing with a Camco # CAM40631 Premium Water Filter System that filters out contaminates above 5 microns in size - same as KW1 spec. Works in any orientation including laying on the ground. (Remember when you have to fill your holding...

  • RV Water Filter and Regulator
    Our water filters like # CAM40631 need to be used after the water goes through a regulator and is reduced to 60 psi or less. For a water regulator you can use # A01-1122VP which will keep the pressure at 50 to 55 psi.

  • Recommended In-Line Water Filtration System for RV
    For an inline water filter, I recommend the Camco RV and Marine Disposable Water Filter w/ Hose Protector - KDF/Carbon # CAM40043. This will give you a 100 micron barrier to remove bacteria, odor, chlorine, and more. It is for 1 camping season use. Another option is to use the Camco RV and Marine Premium Water Filter w/ Replaceable Cartridge and Hose Extension - KDF/Carbon # CAM40631 along with the Camco Replacement KDF/Carbon Filter Cartridge for RV and Marine Premium Water Filter...

  • Replacement Water Filter Dimensions
    We do not have the water filter with the exact measurements you gave. You may consider replacing your filter with the Camco Replacement KDF/Carbon Filter Cartridge for RV and Marine Premium Water Filter # CAM40621 which works with the very common Camco RV and Marine Premium Water Filter w/ Replaceable Cartridge and Hose Extension # CAM40631. This filter is close to the same size but is slightly narrower at 2.6 inches at the caps and slightly longer at 9-3/4 inches.

  • Are RV Water Filter Housings Universal
    According to my contact at Camco, the filter cartridges are pretty universal, but because there's so many companies making them out there, he wouldn't be comfortable with calling the housing that holds the filter universal. Your best bet would be to replace the entire unit, so you'll be assured of getting compatible parts.

  • Does Camco RV Water Filter # CAM40631 Have O-Ring
    Yes there is an o-ring that goes between the black top and the blue lower portion of the Camco RV Premium Water Filter # CAM40631 that you referenced. We don't offer it as a replacement part but you can source them locally at hardware stores.

  • How to Fix a Leaking Water filter
    The Camco Replacement KDF/Carbon Filter Cartridge part # CAM40621 is a direct replacement for the Camco RV and Marine Premium Water Filter part # CAM40631. It is a standard size filter that falls in the cci-10-clw type. If this is the same type filter that cam out of the original (which all signs point to it being that) then you should have no issues. To fix this I would check the filter housing inside and make sure there is no build up or debris in the housing that may cause the filter...

  • Can the Camco Motor Home Water Filter CAM40631 Be Used on RV Water Pumps?
    No, the Camco Motor Home and Boat Premium Water Filter item # CAM40631 is just designed for exterior use on hose lines. For an RV water pump you would want the Clearsource Onboard RV Water Filter System - 2 Canister - 0.2 Micron - Indoor item # CS27FR.

  • Hose for Camco RV and Marine Premium Water Filter
    Although the exact 12 inch hose is not available separately of the Camco RV and Marine Premium Water Filter # CAM40631, it is simply a standard garden hose connection so what you can do is use the Camco RV Drinking Water Hose # CAM22763. This hose is longer, at 4 feet, but will work as an extension hose.

  • Can A City Water Inlet Limit The Flow Of Water Into The RV
    If your city water inlet has a backcheck valve there is the possibility that it's clogged or damaged in some way that it's limiting the flow of water. There's isn't a way to really fix the backcheck so you'd be looking at replacement of the inlet. If you have a recessed mount design then you'll want part # 37262125, and for a surface mount design you'll want part # 37262165. You'll want to put some non-sag sealant # 344270341437-1 around the outer edge of the flange for a waterproof seal.

  • Can The Low-Flow Aerator On The RV Kitchen Faucet 277-000129 Be Removed For Cleaning
    I spoke with the manufacturer of RV Kitchen Faucet w/ Pull Down Spout # 277-000129 and they were able to confirm the aerator is removable from the end of the pull down spout for cleaning. However, the aerator is not really designed to be a water filter and if you are having issues with sand getting into the water tank I recommend to add the water filter # CAM40631. The water filter will help clean the water before it even enters the RV.

    We do sell a replacement filter cartridge for the Camco RV and Marine Premium Water Filter # CAM40631. The cartridge part number is # CAM40621. Camco does not offer a replacement O-ring/gasket part but I think I can help you.
