Custom Molded Grey Water Tank for RAM Promaster Van - Installation

[@NVPJ]

Got mine. Installation was easy - great tank. For anyone intimidated by his (comedic) struggling with the rivnuts, there is a MUCH easier way. Do not try to compress them in one single go! That is way too hard because the handles are out parallel to the work surface and it is like trying to bend a 2x4 to push the handles together. Only screw the rivnut on so that the tool handles come maybe 4" inches apart. A quick squeeze and the handles can easily be pulled together. You repeat that maybe 3 times and on the last squeeze you'll see the rivnut is firmly mounted. Much easier. One other tidbit - after installing your rivnut, put in a bolt and try torquing it down to whatever you plan to do when installing the tank supports. If you can't get the bolt in, you've stripped the rivnut and will need to drill it out (7/8" bit) and put in a new one. If they tighten up and can be removed with no problem, great! But if you are tightening them and notice the rivnut starts to spin, stop immediately, remove the bolt, and tighten the rivnut with the tool some more. It must not spin at all. Doing this with each rivnut as you install it is WAY easier than getting the tank mostly mounted and then realizing you have a problem with a nut and it is now harder to fix with the tank in the way.

Could this be ordered with the outlet on the driver’s side? If you’re in a campground, the dump is always on the driver side. I wouldn’t want to place the picnic table over the sewer hose. 😮

Excellent video!

[@kaciesvanlife]

Just to let you guys know, between 4:00-5:15, the hole placements you have circled for holes #2, #4, and #6 in the diagrams are all incorrect, they should all be one hole further to the passenger side looking at the diagrams. Otherwise awesome video

Nice work 👍

[@gracerodriguez3516]

Awesome thank you

[@garrets6376]

Awesome! Thanks!

[@Lsarsozo]

Great video. Do you have any that show the plumbing into the tank?

[@VanlifeOutfitters]

Thanks! We do have another video on plumbing drains: studio.kzbin.info-_7AMbKBAiA/edit

[@eksine]

the comedy is gold

[@MikeTalley]

How does this hold up in cold weather? Does it freeze solid and then overflow?

[@VanlifeOutfitters]

These can freeze solid with no negative effects but you will need to make sure the drain lines can also freeze.

I noticed that in your plumbing video, you used a vent line from the shower which went out the side of the van. I am trying to drain my shower with a Hepvo valve below the van to conserve shower height. Is it possible to vent the tank on top or out the side somehow? I have seen some other designs that added an always-open hole at the top of the tank that served as both a vent as well as overflow. Any suggestions would be great!

[@VanlifeOutfitters]

There are many ways to vent the tank. In your situation, I would recommend ordering the tank with a second 1-1/2" inlet in location other than your shower drain inlet and then plumb that to a vent somewhere - sidewall of the van, roof, etc. An "always-open" hole would work as well but it would risk draining grey water where it's not allowed.

[@mark.sternig]

@@VanlifeOutfitters really appreciate the feedback on the venting and think that we have a plan. I went to order the tank with some extra inlets (sink, vent, shower, toilet urine tube), but it looks like I can only add up to two. Any suggestions? I was looking at inlets on positions 4 and 5 (drivers side for shower and toilet) and 2 (passenger side for sink) and 7 (rear for vent). I as a little concerned about the vent and that it may be lower on the tank and be able to get water into it. Should this vent be connected and always higher than the tank itself? If that's the case, one option might be to T off of the sink drain just after the HepVo trap, and then run it out the side of the van.

[@jamessjchong]

thinking about purchasing this one, how do most people connect their sink to their gray water? he doesnt show him drilling a hole in the Van for the pipe or anything

Hey there, this other blog post/video might be helpful: www.vanlifeoutfitters.com/camper-van-drains-and-grey-tank-plumbing-overview-video/

[@thewildrosekitchen521]

How much is the kit? Link to purchase ???

[@VanlifeOutfitters]

Here you go, it's also in the video description: www.vanlifeoutfitters.com/store/promaster-undermount-grey-water-tank/

[@sharimctiver8952]

Do you sell an option for a smaller diameter outlet on this tank? Since it is gray water, the 3" diameter is not necessary.

[@VanlifeOutfitters]

The 3" dump opening is molded into the tank but we have several options for dumping including a 3/4" motorized ball valve.

[@rainrobin4505]

Could this be converted to be a fresh water tank?

[@VanlifeOutfitters]

Yes, it could be used as a fresh water tank. It's made of Polyethylene which does not contain BPA and is FDA compliant for drinking water (which means these can also be used to hold drinking water.) www.vanlifeoutfitters.com/store/promaster-undermount-grey-water-tank/ You would probably want the 3/4" motorized ball valve option for the drain and to add the 1/2" female NPT spin welded fitting we offer that would be plumbed to your pump.

[@Steven-e7c]

What if I don't want a huge 3" outlet?

[@VanlifeOutfitters]

We offer a 3/4" motorized ball valve option. www.vanlifeoutfitters.com/store/promaster-undermount-grey-water-tank/

[@Steven-e7c]

@Vanlife Outfitters thanks. Do you have a photo of it attached to the tank on your website?

[@sixfiddy9300]

Where is a link to order this 26 gallon gray water tank kit ?

[@VanlifeOutfitters]

Here you go: www.vanlifeoutfitters.com/store/promaster-undermount-grey-water-tank/. We're sold out at the moment but another batch is in production and should be ready soon.

[@paulhornik1591]

How about black water?

[@VanlifeOutfitters]

We wouldn't recommend using it with black water because of the small vents at the top of each high point in the tank. This could be problematic when used as a black tank. Thanks!
