Replacing your water pump, faucet and water line: 

With over 400 of our vans on the road — many of them more than five years old — we've learned a lot about what works and what doesn’t. One of the most persistent problem areas has been the water system, with the most common issue being the submersible pump seizing up.

We’ve always used the best pumps available, but we still see a dozen or more fail each year. Until now, the fix required shipping your water jug back to us so we could install a new pump — a tricky DIY job due to the waterproof wiring and soldered 1/4" jack connection.

We’ve also seen occasional faucet failures where the electrical contacts stop working. And over time, the water hose can develop stains from sitting water, and replacing those lines hasn’t been an easy DIY task either.

But good news — we’ve come up with a solution for all of it. And even better: you can do it yourself!

Dometic makes an all-in-one water faucet with a built-in pump and rechargeable battery. It’s called the Dometic GO Hydration Water Faucet, and it’s awesome. Even better, it uses the same water connector we originally installed on your jug.

Super quick fix!

- You can use it right away without removing your old faucet. Just pop the included water line connector into your waterbottle and set the faucet next to your sink. This Gets you back in business and you can do the full install at a later time by following the directions below.

(Photo Above) is it installed over the old hole from where the old faucet used to go. As you can see the water line runs out the back of the faucet and down over the countertop where it runs around and into the top of the water bottle (photo below). The connector fits right into the connector on the top of your water bottle.

How to Remove Your Faucet

To remove the faucet, you’ll first need to disconnect the water line from the bottom. Depending on when we built your van, you'll have one of three types of hose clamps:

1. Crimp Clamp (early vans)

2. Standard Hose Clamp (middle vans)

3. Thumb-Screw Clamp (recent vans)

🔧 Removing a Crimp Clamp

This is the trickiest of the three, but still totally doable.

• Find a flat-head screwdriver that fits into the small loop on the side of the clamp.

• Work the screwdriver back and forth inside that loop — after a few wiggles, the clamp should pop loose.

Pro tip: We always used crimp clamps on the pump end of the water line, which is easier to access. Practice on that end first to get the hang of it.
The faucet end is harder to see (it's up under the counter behind the sink), so you’ll have to do it by feel.

🔧 Removing a Standard Hose Clamp

This type can be loosened with either:

• A flat-head screwdriver

• A small socket wrench (usually 1/4", but check — sizes can vary)

Again, you’ll be working blind under the sink, but refer to the photos to help identify what you’re feeling for.

🔧 Removing a Thumb-Screw Clamp

Lucky you! If you’ve got the red, easy-turn clamp, you can just loosen it by hand.
We started using these to make future faucet replacements easier.

🧰 Removing the Water Line

Once the clamp is off, grip the water line firmly and:

• Pull down while gently wiggling it side to side

• It may take a bit of force, so don’t be afraid to muscle it a little

✂️ Disconnecting the Faucet Wires

Now disconnect the power wires:

• In earlier vans, you’ll need to cut both wires

• In some builds, only one wire has a connector

• In the most recent vans, both wires have connectors

If you cut the wires, wrap the ends with electrical tape.

🛠 Removing the Faucet

You’ll see a nut on the bottom of the faucet — but don’t worry about trying to get a wrench on it.

• Just hold the nut by hand from underneath

• Twist the faucet from the top — once it loosens, unscrew it the rest of the way from below

🧼 Final Steps

• Clean the area around the faucet hole

• Stick down the metal cup from Dometic using the provided double-sided tape

That’s it — you’re done with the faucet portion of the install!

Remove the Pump from the Tank

1. If you haven’t already, disconnect the pump from the end of the water line.
   Reach into the tank, grab the pump, and pull it out so you can work on it more easily. It will be attached with a crimp clamp, which you can remove the same way as described in the faucet instructions.

2. Remove the upper water line from the tank.

   • This part is secured with a standard hose clamp (usually 1/4" screw head).

   • Use a screwdriver or small socket to loosen the clamp.

   • Once the clamp is loose, pull the hose down while gently wiggling it side to side until it pops off.

3. Cut and remove the pump wire.

   • Cut the wire that exits through the top of the tank.

   • Pull the cut wire down into the tank along with the pump and discard both.

4. Install the new water hose.

   • Use a piece of 3/8” food-grade water hose long enough to reach the bottom of the tank.

   • Push it onto the same fitting where the old hose was removed from.

   • Since there’s no longer a heavy pump pulling on it, you likely won’t need a hose clamp here. But if it does pop off later, now you know how to fix it!

5. Seal the old wire hole.

   • To plug the hole where the wire used to run, you can use a simple DIY solution:

   • Roll a small piece of aluminum foil into a tight “log” that fits snugly in the hole.

   • Insert the foil plug and tighten the nut that compresses the rubber seal around it.

   • You may need to hold the rubber fitting from inside the tank while you tighten.

6. Clean the tank.

   • If the inside feels slimy, reach in with a rag or sponge and scrub it down.

   • Rinse with a strong vinegar solution or One-Step (listed on our Recommended Products page), followed by a couple of clean water rinses.

🎉 That’s it! You now have a fresh, fully updated water system!
