What would just connecting to a city water spigot in a campground need an article for? After all you take your hose and attach to the spigot, connect the other end of the hose to your city water connection on your Roadtrek - and turn on the water. Right? Well almost right.
There are two things to do before what is simply described above. The first thing to be aware of is that many of these spigots are close to the ground and in many campgrounds there are dogs and other animals wandering around the campground during the day - and at night. The dogs, especially, find these low down city water spigots a favorite thing to lift their leg against and cover the spigot at its opening and and the screw threads that you are going to attach your city water hose to. Yuck! This common.
The most suggested way of disinfecting the spigot is to mix a solution of bleach and water in a spray bottle and spray that into the spigot opening and allover the outside of the spigot. We did this when we first got our Roadtrek. We would mix up a batch in a spray bottle and keep it from trip to trip. Then we found out that the bleach loses its effectiveness over time - and especially mixed like this in the heat of the summer. So we started mixing it just before we would use it - and wind up discarding more than we sprayed - and it was a pain to do this when you are trying to get through hooking up.
I recently found out about a better spray to disinfect a campground spigot for this reason from an RV TV streaming show. They said to spray hydrogen peroxide and that it was available already in spray bottles. As long as hydrogen peroxide is kept in its brown bottle and kept closed it lasts for a very long time. I went out looking for hydrogen peroxide in a spray bottle and found out that it is sold in Walmart stores in the pharmacy department.
This bottle is very inexpensive and it is easy to store in the outside cabinet on the side of the Roadtrek with your hoses. Spray the inside of the spigot hole and all around the spigot head. Let is sit for five minutes and then turn on the water to flush out the spigot before you connect you city water hose.
There is just one more thing to always do when you are connecting a city water hose to your Roadtrek. You MUST attach a Water Pressure Regulator. The best place to attach this is between the city water hose and the campground spigot. After you spray the spigot with the hydrogen peroxide - attach the city water connection to the spigot and then attach you city water FRESH hose (yes there is a special hose to use on an RV - these hoses have no lead in their connections and they are usually white hoses or a white with a blue stripe hose, or a blue hose. The hose is labeled on its packaging as "drinking water safe" or "safe for potable water".
Water pressure regulators for RVs come different ways. The one above has the max pressure it will limit through it permanently set to 40 psi - which is the most pressure you want in the Roadtrek or any RV plumbing that will not burst the pipes. There are other preset city water pressure regulators that have an analog meter attached to see the water pressure - which is not really necessary. Then there are water pressure regulators that you set to the allowed pressure. They also have an analog meter attached to see what the water pressure is - which for this type of water pressure regulator is very important. This might seem like the best to get, but if you forget to set it or it has moved off the setting you set it to last time, you will damage your Roadtrek's plumbing.
RV accessories retailers online have all of these. Many Walmart stores have RV accessories in their Auto aisles in a section of their own on the shelves. They have the water pressure regulator shown above in the photo. They may also have a water pressure regulator that looks the same but is made of blue plastic. I do not recommend buying the plastic one - get the brass one. Plastic too easily can break or get a small crack and the pressure will be effected.
So hooking up to city water is a little more than just connecting the hose - but it is just as easy when you add these few steps.
Also - if you are concerned about the water that comes out of a city water spigot at a campground, you can buy a filter that is attached to your city water hose and it will filter all water going into your Roadtrek (even when filling the fresh tanks through the door openings). This is a thick walled plastic cylinder about a foot long and maybe two and a half to three inches in diameter. I have a four foot fresh water hose that I put between my pressure regulator and my long city water hose and the water filter is attached between. We also have a regular Brita kitchen sink water filter - the same that goes on kitchen sinks at home - on the kitchen sink faucet in the Roadtrek. This lets you know when the filter needs to be changed - and then you just take out the old cartridge and drop in a new one. The hose filter is also found at Walmart in the RV accessories section and the Brita water filter can be found in most places that sell household items.
