Nice water tank. Perfect size for my need. As usual etrailer was the price leader with lightening fast delivery. No reason to ever look elsewhere for your vehicle/trailer needs.



by:

Nice looking and very well put together from the mounting hole to the weld around the edges. Very impressed with the fresh water tank. Haven't put it in yet, but will come back with an update when I do. These tanks will fit nicely, the measurements are right and correct to what they say, about them in the specification section.

I got this to upgrade a small teardrop camper. Very pleased with the product and with etrailer's service. The order was filled very quickly and I received my items 3 days ahead of the estimated delivery date. Excellent service!



by:

I installed this tank in my Sprinter van RV conversion project. It has functioned very well, and is well made. I have it tucked into the back of a floor height cabinet, and is hooked up to a to a pump and my sink. I took a bit to get around to installing it after I bought it, but I have been using it for months and it is great!



by:

Great upgrade for my popup trailer! No leaks or issues after 1 year and several camping trips. Didn’t take too long to attach the fittings and install. Great support from etrailer too!



by:

This water tank worked perfectly for my need. Its durable, and easy to install fittings into. Just used my drill and a hole saw to install the fill port. The fitting kit came with everything needed to make it a simple process.

looks like a great water tank. eventually will be installed in our Sprinter conversion van.

As always etrailer comes through with best pricing and fast shipping so I keep coming back.

Great design that allows for many layout options. I have a small 6'x12' converted cargo trailer. The tank does not take up a lot of real estate which is exactly what I needed. I wanted floor space for comfortable movement inside the trailer and for cargo hauling when not camping. I had to modify the tank in order to add a water guage sensor and a screw out deck plate to clean the tank. I do not recommend these modifications to be implemented by the manufacturer as they may limit the orientation options. The tank is built very well. It has a solid interior spine that provides stability. I was able to see the inside of the tank when I installed the deck plate. I don't have any complaints so far and I believe this tank will serve me for many years. Just remember to measure 10 times and cut once for any modifications. It plastic that holds water, so there is zero margin for errors.



by:

I actually have not installed it, my husband discovered the other tank was not busted, it just did not have a cap and the water was draining because of that, it is put up in storage for a just in case.



by:

Nice water tank that fits in my Jeep ni cely.

Part arrived in good shape received before I anticipated very happy with that thank you very much



by:

Exactly what I expected



by:

The first one I ordered split down the middle upon filling it up and it flooded my van. I probably over pressurized it. It was out of warranty. Because of the size restriction I ordered another one which has been working okay since.



by:

The tank is installed in our Transit van and fits quite well on top of the rest wheel well. I wish it had come with better instructions on the size of threaded that fit and how to open the holes.



by:

Installed it and discovered a leak. Will be asking for a replacement.

That's not good, Mike! I'll get you a replacement!

This was a fast easy Transaction with E-trailer and I use them for just about all my parts for the RV.

The installation was super easy.

This Tank fits quite a few different Models.

When You get it you will need to drill out the already marked holes for your specific needs.

I set my old cracked tank next to this one and just copied what I had with the new replacement tank.

A little bit of plastic glue, which they sell the kit for that too.

Let the new tank dry over night and install in the reverse order you removed it.

Reconnect the lines and your done.

It just does not get any easier then this folks.

  • Location of Fill Ports on Valterra RV Water Tank
    Hi Elliott; the Valterra RV Water Tank # R8048 has three 3/8" threaded fittings on each end of the tank. You can see them in the attached picture, one has a red plug. The tank is only designed to be gravity fed or used with a hand pump, not an electric water pump. What are you using the water tank for?

  • Why Cant The Valterra R8048 Be Used With An Electric Water Pump
    Because the Valterra RV Water Tank # R8048 is a lightweight tank that is baffled for surge control, it is not designed for use with electric water pumps. It would void the warranty if used this way and is why they specifically note on their site: "Not for use with electric pumps, low pressure applications only" Included is our review video for additional informaiton on this product.

  • How Much Does The 48" x 8" x 16" Valterra RV Water Tank R8048 Weigh?
    Hi Jared! The 24 gallon 48" x 8" x 16" Valterra RV Water Tank # R8048 weighs just under 16 pounds (15.8 pounds, to be exact). If you were also wondering how much this would weigh with 24 gallons of water in it (I was), that would be 215 pounds (a gallon of water weighs 8.3 pounds and 24 gallons therein weighs 199.2 pounds). This is fairly relevant as that is a good amount of weight. Where are you planning to install this?

  • Replacement Water Tank For a 2000 Coleman Fleetwood Utah Camper
    Hey, Glenn! We don't have a wide range of tanks but we do have some! I tried to search to see what size tank you have and the most I could pull up was that it "should" be a 26 gallon. The closest that we have is a 24 gallon Valterra tank, part # R8048. You will want to make sure it will fit in the same space, this one is 48" long x 8" wide x 16" tall. If the dimensions don't work, you may have to go with a smaller tank. Here are a few other options: Front Runner Water Tank 17.7 gallons...

  • Looking For Black Water Holding Tank For Jayco 5th Wheel
    Hello Scott, thanks for reaching out. The largest water tank we offer is the Valterra RV Water Tank # R8048 which is 48" x 8" x 16". This tank is more for fresh water though, and we unfortunately do not offer a black water tank that will meet your specifications. Your best bet for that would be to go thru a Jayco dealership.

  • Can the Valterra RV Water Tank # R8066 be Installed So That it is Taller or Shorter
    The Valterra RV Water Tank # R8048 can be installed standing up for laying down as is demonstrated in the 2 attached photos. If you have it oriented so that it sits taller the drain plug will already be in a position to drain properly. Should you choose to mount it so that it has a lower profile you will simply need to use one of the pre-drilled holes as a drain. If you finish drilling them through to the tank you will be able to use them as a drain as you can see in the attached picture...

  • Can Sight Glass be Added to Valterra 24 Gallon Water Tank
    I don't see any reason why you can't add a sight glass to the 24-gallon Valterra RV Water Tank # R8048. These aren't something we offer or have experience with in regards to installation, so you may need to find a way to fabricate or otherwise install one but you can do so if you like. We do not recommend putting a larger fill port in the RV Water Tank # R8048 but you can add a fill kit to make it easier with the Valterra ABS Tank Fill Kit with Threaded Cap # RK909 or Valterra ABS Tank...

  • Can Valterra RV Water Tank # R8048 Be used Laying Flat
    The Valterra RV Water Tank # R8048 could be used on it's side in the orientation that would put it at being 8 inches tall. I pointed out two of the fittings that can be used when laying down in this orientation. You'd just need to punch out the cover for the fitting and you'd see the 3/8 inch fitting there. I attached a review video for this for you to check out as well.

  • What Tool Should Be Used To Knock Out An Inlet/Outlet Hole In A Valterra RV Water Tank
    You can use a hole punch from your local hardware store to knock out the cap of any of the Valterra RV Water Tanks # R8048.

  • Could Valterra RV Water Tank # R8048 be Mounted Vertically
    The only reason mounting the Valterra RV Water Tank # R8048 would be challenging would be the drain hole location. If you could come up with a way for it to be accessed on the bottom of it when vertical this would work just fine. Maybe have a hole cut in the floor so that the line ran to it would go through the floor.

  • Can the Valterra 24 Gallon RV water tank be mounted vertically?
    Thanks for your question Ann. The # R8048 can be mounted in any orientation so there would be no issue with mounting it vertically. You really just want to make sure you have access to one of the pre punched drain locations. There also isn't an issue using this in a home passive solar heating array setup. Of note, this tank is only rated for use in gravity fed systems or with the use of a hand pump. What purpose would this tank serve in your setup?
