Supplies For Your Water Connection
These are supplies that anyone starting off on their first time camping with an RV (Motorhome, Trailer, 5th Wheel) or someone that has been doing it for a while.
Drinking Water
To make sure you have a supply of water, you may want consider carrying bottles of water for drinking just to be safe. For every other use (showers, cooking, dishwashing), you'll need these basics to make sure the water is flowing:
Drinking-Water Hose
You need to make sure you get a hose specifically for drinking water. You want to make sure its BPA and Phthalate free. I found you can stick with the basic hose and most likely you'll want to get a new one every couple years.
Water Filter
Quality of the drinking water is going to vary by campground, city, location, etc. A water filter is critical to ensure safety and taste. This is a water filter used by many. There are fancier and more expensive. This should also include a flex hose as part of this as its another important piece as this will sit off your camper. Later on in the list you'll see a 90 degree elbow which I recommend using which would be what we use to connect to the camper and than to the flex hose.
Water Pressure Regulator
Many people will use the regulator that is set to about 40psi. We started off with that and upgrade to one with a gauge. This will one will come in handy when you have lower water pressure and this will let you adjust. However, I find it most useful when your diagnosing a problem. You will come across a campground where the water pressure is low or you will lose 100% of the pressure. This will tell you pretty fast if the water pressure is the problem vs. you have an issue with the camper.
Hose Splitter
Not everyone needs this, but you'll find most campgrounds with a water hook have a single faucet. If you need on occasion to hook up a hose to wash something down or you have a blank tank flush, its very convenient to have this. Remember, hook this to the water gauge if your going to use this, especially if you have a hose going to your black tank flush. By doing this, you'll ensure all hoses will have the proper pressure for your camper.
90 Degree Elbow
This is a piece of optional equipment. We will use this to connect the water hose / filter to the camper via this 90 degree elbow. For our campers, this seems to take the pressure of the city water connection. You may find out this is not the case for you.
A Water Pitcher
As an extra precaution of making sure the water we use is safe, we also run water through a water pitcher. Carrying plastic bottles of water around isn't the "greenest" way to camp. We like the Brita Stream pitchers. Fills and pours pretty quickly and fits nicely into the fridge.
