How to Hook Up RV to House Water

A recent survey showed that 100% of Rv’ers hooked-up to water at some point in their RV career! …Im joking of course, but you get the point. We need water! 

There are two ways to hook up your water, The “RV Hook up anywhere way”, and the “Permanent RV Water Hook up way”. Don’t you worry we’ll cover both in this post. 

Let’s start with the quick and easy way.


Equipment you’ll need to Connect your RV to home or Campground water supply.

  • A white or blue potable water hose.

    Please Do Not use a green hose! I will go into depth on this later, but for now know that If you don’t have a drinking water hose for your RV you will need to buy one. 

  • A pressure regulator

    There are two options available: A standard RV Water Pressure Regulator OR an Adjustable RV Water Pressure Water Regulator. Both are fine options, and I will cover the differences later on. 

  • An Inline water filter

    (optional) Yes, I said optional, but this will ultimately keep both you and your plumbing healthier, and it does not complicate the setup. 



Steps to hook your RV to Water supply


1. Pull your RV as close to your water spigot as you can. 

2. Connect the pressure regulator to your outdoor spigot. (DO NOT FORGET to attach your regulator!)

3. Install your inline filter on either side of the hose. (optional, but recommended) 

4. Connect your fancy new potable water hose to the regulator now attached to the spigot on the water source. 

5. Connect the water hose to your RV, this will be the inlet on the side. NOTE: Some RVs also have a switch for “City Water” intake.

6. Open a Faucet in your RV ( this is a simple fail-safe as to not over-pressurize the system. Go ahead and turn on the water at the spigot. Make sure water is flowing in the RV and there are no leaks or water spraying in odd places.

Building a Permanent RV Water Hook up at home


Here is the fundamental way to build your own water hook up at home. If you would like a more in depth article about Building a complete RV hook up with water and electricity then read on to “Cost to install RV hookups on land”. 

Steps to Build your own Water Hook Up

1. Pour a concrete pad that is large enough to allow your RV to drive on and offer at least a couple feet on each side to walk. (This step is optional). 


2. Contact your local utilities company first to have someone check for gas and electrical lines before you rent an

 excavator or have that shovel ready.  Dig a trench from your existing water lines to where you would want to put your water and electrical. 

3. Now lay pipe in the trench, underground below the frost line to keep the pipes from freezing. This depth is (0-8ft) and  is highly dependent on your region in the country. 

4. Bury a post, or build  a box that houses the spigots for the water, and the cabling for the electrical wires to go inside. Water and Electricity can be paired in a single hook up, or have their own post. 

Is hooking up to the fresh water tank different?

No, hooking up to the fresh water tank on your RV is no different than connecting to your normal water source. On some RV’s, you’ll have a separate fresh water tank inlet from the city water inlet, that is the only difference. The actual method of connecting to those inlets is the same.
