We finally got round to starting one of the bigger jobs in our van - installing our underslung water tanks. We decided to go for the CAK water tanks that are designed to fit snuggly under the van and make use of some of the recesses in the chassis. Unfortunately, due to the position of our gas tank, we couldn't make the smaller waste water tank fit so we decided to just install the 66 litre fresh tank underneath the van and also to do this on the 'wrong' side, installing it on the drivers side.
The tanks are good but the supplied fittings aren't great so we rust treated them and then had to manually drill fixing points in the chassis members before we could fit the tank. After treating and sealing those, fitting the tank level gauge and insulating it, we were able to fit the tank in place.
The final stage was to connect up the pipework including filler hose from inside the garage and cold feed in to the van. In the next water video we'll show you how we fit and connect our in van water system but for now, we're happy the tank is in place!

Class Job on the tank where you cable tied the blue pipe to the axle It might be a good idea to put some rubber to save the pipe and fitting some kind of mud flap to save all your hard work Insulating the tank wouldnt do any hard to lag the pipes great job by the way not many people would think of Insulating and rust proofing brackets 💯👌 Have thought about wax oil the under carriage of your van class video campervan content you could be on to something there Insulated tanks 💡💡😎👌👍

Just subscribed a week ago and slowly catching up. Love your detailed explanation, your eye for detail and your unbelievable patience! just a question with the tank. There are several raised sections (3 in all) How do they all fill up? Would there be an air lock preventing filling or are they all separately vented?

Hey, it’s basically just a drinking water safe flexible hose pipe like you’d use in the garden. 15mm. I got it from the same place I got the John guest fittings and the 12mm pipe. Quite hard to find admittedly but that’s what it is.

@MultiOutdoorman 9 ай бұрын

There looks like a very small clearance between the tank and the rear axle ? Going over bumps the tank when full might hit this component. Also the springs look straightened-out, consider an air suspension kit for improved height and ride comfort !

@OurVanPlan 9 ай бұрын

It’s close but plenty of clearance. Yeah the springs were flat so I tried the sumo springs which helped a lot (particularly with stability round corners) but ended up changing to dual lead springs which make a massive difference and it’s a nice comfortable ride now.

mate this is fantastic. Really helpful and makes one feel one can install a tank without stress. I have a motorhome on a Peugeot boxer frame. one thing I dont understand is there i you call the "fill" @21min and 12 seconds. and the cold fill ? Whats the difference?

@OurVanPlan 4 ай бұрын

Thanks glad you found it helpful. It’s certainly more straight forward than I’d expected. Hmm there’s only a main fill for the tank and then the cold feed back into the van plus of course the drain to empty the tank. Probably got my words muddled 😂

@user-eh8bp2im5q 6 ай бұрын

Hi, Great video and explanation, thanks. I'm converting the same van as yours and at the moment I'm planning the water and gas tanks. A question: I made a template of the larger fresh water tank (based on dimensions from CAK) and when positioned on the van the sweep of the handbrake cable in front of the rear axle cuts the corner of the tank, not much but it looks like it might prevent the tank fitting properly. How did you get round this?

@OurVanPlan 6 ай бұрын

Glad you found it useful. I didn’t have any issues with the hand brake cable but I know what you mean. I think the tank can push forward to keep it clear enough. There’s a reasonable amount of movement when the bumps of the tank are up in the gaps between the chassis struts.

@user-eh8bp2im5q 6 ай бұрын

Hi and thanks again, On your video it looks like the handbrake cable is just clear of the tank. I don't suppose there is any difference in the routing of this cable between your van and ours (2023) but, you never know!! If you say it fitted then I'll believe you. My thinking is to use 2 of the larger tanks (1 for fresh the other for grey) so there is a bit more clearance to get the gas tank inspection cover off. (The CAK 224W looks to be a bit further towards the front of the van than the 223F). It's so difficult to plan these things without having the bits in front of you. C'est la vie!! Ron@@OurVanPlan

@stringsofbean1073 Жыл бұрын

Hi mate, can I ask what specific pipe you used for the feed up into your van? Was it an internal diameter of 15mm or smaller?

@OurVanPlan Жыл бұрын

Yeah the cold feed into the van is 15mm flexible hose and seems to do the trick. It’s more like hosepipe than the 12mm internal plumbing pipe work.

@RoddyPerry 2 жыл бұрын

I am building a van myself. I took inspiration from your ceiling and made one similar to yours so thank you and sorry for copying your design! I am a bit behind your build so this video comes handy. I am terrified of making holes though my brand new spotless floor! As you mentioned, I think the entry pipe will accumulate water in the elbow and possible freeze if the temperatures drop below 0. Do you have enough room to insulate the pipe? The others are quite small so I'm guessing that won't be a problem. It would be a shame if the pipe froze after all that Xmas present work done on the tank!

@OurVanPlan 2 жыл бұрын

Your ceiling sounds great and we saw the design from someone else so sharing the love for the slatted ceiling! I still need to fully test the water filler. I think some will accumulate so will need to deal with that. There is definitely space to insulate so I’ll do that and keep everything crossed!

Yeah it’s just the regulator and we could move it but it’s working ok with just one tank at the mo. You can definitely fit both plus the gas tank, it’s just quite right. The tanks come up close to the cross beam that the gas tank fits to.
