We hesitated to install a draft beer system, but we finally installed a pressurized water system instead. Here are the main features:

  • Easy to winterize, easy to rinse & drain
  • Pressurized (55 PSI)
  • 25 gallons fresh water tank
  • Grey water is dumped in a 4 gallons Aqua-tainer
  • Portable Propane Shower




40 hours (this is very approximate, as we lost track of time…)



1100$ USD approx (including the Mr Heater Portable Shower)

First, we had to make some room. The tank is installed above the wheel arch:

Water System Installation Camper Van Conversion (11)

The Tank Support (it’s attached to the bed frames)


Water System Installation Camper Van Conversion (6)

The Tank Support Supporting the Tank!

There is a “bumper” at the forward and rear of the tank (so it stays in place in case of sudden braking) and it’s attached with a strap (for now) so it can be easily taken out of the van for draining or rinsing.


Fresh Water Tank

The tank (http://amzn.to/2o9rVBw) holds 25 gallons and the dimensions are 8″ x 16″ x 48″. There are more sizes to choose from: 10,12,15,20 gallons and so on, check them here: amzn.to/2ntzEaf

The tank comes with all the fittings built-in the tank: 1¼” fill hole, ½” FPT vent, ½” FPT drain or pump connection in the back and ½” FPT drain or pump connection in the front. The fittings are female-threaded, but you will have to drill them depending on which one you plan on using (hey that’s easy to do).


Holes in the back of the water tank. We’re using the bottom hole as a drain hole.



Hole in the front of the water tank. We’re using the hole for the pump.




Some hardware is required to connect the pump, the water tank and the faucet: high-pressure braided hose 1/2″ I.D. (http://amzn.to/2mYVt5p), ½ MPT Sureflo fittings straight with wingnut (http://amzn.to/2nulnKk) or elbow with wingnut (http://amzn.to/2nqWFtq), ½ MPT plastic fittings (http://amzn.to/2ou2oAn) and hose clamps (http://amzn.to/2nufFrT). DO NOT USE METAL FITTINGS as you will damage the (very) fragile plastic threads in the water tank.


Installation Tips for Plastic Fittings

  • Do not use Teflon tape or Teflon paste! These are lubricant, not sealant, and will promote over-tightening.
  • Don’t over-tighten: finger tighten plus one or two turns (because the threads are tapered, over-tightening will make the female fitting crack)
  • Use plastic-safe thread sealant (not lubricant) such as LA-CO Plato-Joint (http://amzn.to/2nFhT70)

LA-CO Plasto-Joint. Buy from Amazon


We carry a 25′ food-grade (edit: we will swap it for a 50′ length…) water hose (http://amzn.to/2nFgmOd) to fill the tank through the fill hole:

Camco 25 feet Hose

Camco 25 feet Food-Grade Hose. Buy from Amazon.

(we first looked for an expandable hose, but we could not find one that is lead-free)


To increase our chance of finding water while we’re on the road, we carry a neat Water Bandit. It can be fitted on almost any tap thanks to the rubber side, then a hose can be connected to it thanks to the “garden-hose-fitting” on the other side:

Following this post, many of you recommended us to get a Sillcock Key. Apparently, this tool can open water supplies of several rest areas, campgrounds, corner stores, etc. We’ll give it a try! Here is the tool:

Cobra Products PST154 4-Way Sillcock Key

The fill hole is plugged using a Test Plug (http://amzn.to/2nIEWj8):


Test Plug. This one fits perfectly in the fill hole: Buy from Amazon.

The changing volume of water in the tank must be replaced with air; this is achieved through the filling vent. To prevent water spillage, we connected a 3/8″ I.D. clear hose (http://amzn.to/2nu7wnq) via a 1/2″ MPT to 3/8″ barb fitting (http://amzn.to/2oLeDI9 ) and raised it a few inches above the tank (shown on the first picture in this post).

To drain the tank, we installed a PVC ball valve (http://amzn.to/2nr1mni) attached via a few elbows and straight fittings (http://amzn.to/2nLColM) (shown in the first picture in this post). We can connect a hose to it when we want to drain the tank.


Water Pump & Accumulator

We chose to install the Shurflo Revolution 4008 water pump (http://amzn.to/2kFINP8), because it’s been around for a while and it can be trusted. It delivers 3 gallons per minute at 55 PSI. It’s a diaphragm pump, meaning there is no on-off switch; it’s pressure sensitive. The pump will turn on when the pressure in the hose drop below 40 PSI, that is when we open the tap at the faucet. The pump will turn off when the pressure in the hose raise above 55 PSI, that is when there is no demand for water. It is self-primed and can be run dry, neat!

This pump has an internal bypass to prevent rapid-cycling. This is when the pump will turn on-off-on-off-on-off very rapidly; it occurs generally when a very low volume of water is demanded at the faucet. That being said, after reading some reviews on the internet, we still decided to install an accumulator (http://amzn.to/2kFQ6q8) to prevent rapid-cycling. It might not be required, but it can apparently improve things a little.

Water System Installation Camper Van Conversion (10)

Pump (on the left) & Accumulator (on the right)


The pump and accumulator are protected by a box and can be turned on/off easily with this switch. We  HIGHLY recommend an easy-to-access switch to prevent spillage or to turn off the pump when leaving the van…


Think inside the box:

We use the following switch for the water pump and for the cargo lights; we really like the design and the “feel” of it:

JR Product Switch ON-OFF

We splurged on a very nice Dometic sink with integrated folding faucet & folding glass lid (model VA7306, Buy from eBay). We already covered the installation into the cabinet in our Sink & Stove Cabinet article. The sink comes with two ½” MPT fitting (one for cold water, one for hot water), but we’re only using the cold water fitting (make sure to plug the unused fitting with an end cap to prevent spillage! Yes, we learnt that the hard way…).

Folding Sink in action!



Notice the end cap on the unused sink fitting…


Grey Water Tank

We went for a modest installation that suits our modest needs: just a 4 gallons Aqua-Tainer (http://amzn.to/2kFK58U) that we empty every other day or so. The Aqua-Tainer is connected with a Camco Water Drain (http://amzn.to/2kFOH2Q) and a garden hose quick-release (http://amzn.to/2oEe1rr) for quick & easy dumping.


Super Simple Grey Water Management!



We have running water!



Hot Shower

We wanted to have a tank-less solution for the shower, for energy efficiency sake. We went for the Mr Heater BOSS XCW20 portable propane shower (http://amzn.to/2oD3JIy) because:

  1. It is very well rated
  2. It is very safe (gas is cut if it tips-over)
  3. It is portable (it has an internal battery and can be operated with 1 pound propane cylinder)
  4. Output temperature can be controlled with the digital panel
  5. It has a faucet on the side

The Mr Heater BOSS cannot be integrated to a pressurized water system; it has to pump water from a jug (such as the aqua-tainer we’re using). That’s fine with us.



Frozen water causes damage to the pump, accumulator, pipes and Mr Heater BOSS. Our system (or any other system if that matter) must be winterized if temperatures are below freezing. It seems that there are two types of anti-freeze:

  1. Ethanol
  2. Propylene/Glycol

We’re not expert on the topic, but we read that ethanol based anti-freeze is very flammable, could damage the seals of the components and could affect the taste of the water. Propylene/Glycol based anti-freeze is not combustible, help to lubricate the seals of the components and is tasteless. I guess we will use Propylene/Glycol based anti-freeze…




Our system is working great, we’ll see how it performs in the long run!

We already have some improvement in mind: we will add some kind of spray nozzle for a shower / bike wash at the back of the van. (the idea is to bypass the Mr Heater for cold showers & bike wash). Wait for it…

    Hey Antoine!

    Quick question?

    What made you choose the boss water heater over the eco temp l5 overall?

    I’m leaning towards the ecotemp but I am also installing 40 gallons of water storage capacity as well.

    Are you planning to have the boss water heater pull water from still sources such as a lake since it has an integrated pump?

    • Comment by Antoine

      Antoine Reply April 19, 2017 at 1:19 pm

      I only heard good things about the Eccotemp L5 and it’s much cheaper than the Mr Heater. We leaned toward the Mr Heater for the portability: in summer we will shower outside, in winter inside. The Eccotemp L5 claims 30-35 degrees rise VS the Mr Heater up to 45 degrees rise (i did not verified that). The Eccotemp L5 can be incorporated into a camper water system, the Mr Heater cannot (as we mentioned in our post). That was the majors Pros/Cons I think.

      There is no clear winner/loser here… decisions, decisions, decisions…

      P.S. The manual of the Mr Heater proscribe from using the unit from a lake or any source that might contain particles/dust/debris… I guess we could have some kind of filter.

    Thanks for the reply! I liked the fact the L5 can plug right into the vans water system and the cheaper cost. I believe that will be the model we will go with but its open to change as we haven’t ordered a water heater yet.

    Looks like you are getting close to the finish line with your build! Super exciting. Im looking forward to seeing the final product rolling on to the start of your adventure!

    Very nice and inspiring. Using this setup, are you able to connect the heater to the pressured water system? I wonder how you did the heater connections. Thanks!

      Antoine Reply April 20, 2017 at 8:06 am

      Hi Diego!
      Are you referring to the Mr Heater (shower)? If so, no it cannot be connected to the system. The Mr Heater (shower) uses its own pump, so water is pumped from a jug such as the Aquatainer http://amzn.to/2pG1PUP. If you wish to connect a tankless water heater, look for the Eccotemp L5 (or similar): http://amzn.to/2o7qPYb.

    Have some direction for you as far as outdoor shower is concerned. I went a little more hardcode on the bracing and the strapping, and I’d recommend the same. 20+ gallons of water sloshing around is a TON of momentum force.

    I got the shower off Amazon too (https://www.amazon.com/gp/product/B019F81FQ0/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) and here it is installed. It’s pretty great. I also went with a little more robust drain than a PVC valve. You don’t want something accidentally hitting it and cracking it. Lastly, if you install a nice beauty panel on the back like I did, you can get a pretty water inlet (with vent hole too) here https://www.amazon.com/gp/product/B00C5SOXNU/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1

      Nice, your build look super clean! Well done!
      Can you adjust the spray on your shower? I’d like to have a small, high-pressure spray for the bikes..

      Thanks for the tips!

        Tom Reply April 20, 2017 at 5:07 pm

        You cannot, it’s sort of a low pressure-ish spray. But it’s actually PERFECT for the bikes. You don’t want to use a small high pressure spray to wash bikes and smoosh water into all the bearings/etc.

        Speaking of bikes, I 100% stole your bike rack idea and it’s awesome. Thanks for the links and detailed writeup. You mentioned about some sort of protection for the floor of the tray. I originally tried a vinyl drawer liner and it looked pretty decent, but was peeling up/etc. Kinda meh. So I painted the whole thing gray to match my wall panels and decided to start sticker bombing the tray portion. Totally worked and I’ve been loving it.

    Derp, can’t edit my post. I also added an extra metal strap front to end since I took those pics. I do REALLY like the quick release for your grey water tank. Going to totally steal that, as right now I have a garden hose attachment on mine and it’s a pain to unscrew.
