I see that some folks carry pressure reducers for their city water setup. Why? I have a couple I used with my previous SOB, but it is my understanding that it is a part of the AS system as supplied from the factory. Do you know something I don't, or are you just bring redundant?

Here's an example.
*If you have a 25' 1/2" diameter hose, with 40psi of water pressure at the spigot, your maximum flow rate will be about 24 gallons per minute— not counting the additional length of plumbing inside the trailer between the inlet and the faucet or shower head that further reduces the flow rate.
* If the hose is increased to 50 feet long and 5/8" in diameter, the maximum flow would be 22 gpm. But if you use 50' of 1/2" hose the flow rate slows to just 12 gpm.
* If you increase the length to 75 feet and the diameter to 3/4", the maximum flow rate is 27 gpm. But if you use 75' of 1/2" hose, the flow rate drops to 9 gpm.
So for every 25 feet of length, the hose diameter should go up by 1/8" to keep nearly the same rate of flow in the hose for a given water pressure. If you carry a 25' 1/2" hose as your main, then a 25' spare hose should be 5/8" diameter, and you can hook up the larger-diameter hose at the spigot and the smaller diameter hose at the trailer to minimize losses in flow rate.
Every thing you say is accurate and very well explained however one thing I don't understand is how does the 5/8" hose increase the flow if its connected to the 1/2" plumbing in the Airstream? In other words, if you have a 5/8 hose that is not connected to anything it will flow unrestricted at 22 gpm. Now if the 5/8 hose is connected to a 1/2" hose (or the 1/2" AS plumbing) doesn't the !/2" hose restrict the flow or is it still 22 gpm ?

I think it's to protect the external hose, or something. Airstreams do have a built-in water pressure regulator within the hose connection and that has served us seven years and 1400 nights camping without any problem.

We don't carry stuff around the country we rarely if ever need. (Well. for some reason we always take some clothing we never wear. I have lightened the tool kit substantially though. She has some things in her kitchen tool kit I need to go through when she's not looking.)

Before ordering, find out what your dealer provides, as m.hony said. My dealer provided a starter kit with fresh water hose and waste dump kit along with some toilet tank chemical and a mosquito repellent. Not the highest quality nor as long as I eventually wanted/needed, but it got me going and I used them on my trip home.

Agreed on the flexibility of shorter lengths but you increase the risk of spillage by increasing the number of connection points. Typically leakage takes place at the hose couplers and not with the failure of the hose itself. Failures are mostly due to gaskets falling out or becoming cocked, not fully locking the couplers together and hose not securely attached to the coupler itself. Mostly due to user error, not paying attention, haste and lack of inspection.

Also, three 5’ lengths do not compress as much as one 15’ length due to the intermediate rigid couplers, so be aware if storage length space is limited.

This is their blue water safe hose and is quite rigid. You will find it is a handful in cooler weather, as HiJoeSilver indicated and tends to kink due to its rigidity. I recommend you stick with their white hose.

You can remove one of the coupler ends and trim the hose length so that it fits the tube. You won’t reduce the overall hose length that much. I’ve done this and according to my notes you reduce the extended length 3.7” for every 1” of compressed length removed. Do the trimming in small increments to lessen the risk of over trimming. Not near my trailer now, so I can’t give you exact numbers. Note, you will need a wire cutter as well as a sharp tool.

It is difficult to tell someone else what they will need. After a few years under my belt now I would say to start with the basics HOWEVER, I had to upgrade my basics due to not having long enough cords/hoses. I recommend 50 foot and the larger diameter drinking hose. One place I stayed the water tap was clear off in the woods away from the site- they had run a straight line between front/back sites and there was wooded area between. I had to get a longer hose after going and asking where the water hookup was. You might consider those newer crinkle hoses that really shrink down when not in use. I bought the nevRkink and hate it. I have never seen a hose that kinked more- every few inches. Also consider extensions or second hoses 25x2 if the price is good. That way you can have less weight and pull out more length only if needed.

I have one 10' water hose and two 20' water hoses. Almost always one ten footer will be enough.

I bought a 25' shore power cord extension; So far I have never needed to use it, but you never know. I also have a 50 Amp dog bone and have used it three times. Rarely, but a few places only have a 50 Amp receptacle at the power post.

I have a water pressure regulator and only use it when the camp ground has very high water pressure; They will let you know at the office if they have extra high water pressure. I use it at the spigot to protect my hose.

Hi, my post previous to your's explains it. To protect your hose.

Rich,
These are called Cord Pro. http://www.cordpro.com.

I use the XL size for my 30A Electrical cord and the regular size for my 25' hoses. I love these.

I think Camping World carries therm.

Drinking hoses, some have plastic connections. I would stay away from those. Speaking from experience like most plastic they do not handle UV or repeated use very well and will fail at the worst possible time. Brand is not important. I recommend 5/8 ID with quality heavy duty brass end connections. I have yet to find a rubber hose that will not eventually kink or develope cracks in the outer cover. I do have a length of 1/2 inch coiled plastic hose. It seems to significantly decrease the pressure. Only benefit I can see is it does store in a small space. I continue to carry it to use for a secondary outside shower/rinse hose using a splitter and a spray head.

Don't forget your Airstream has over 30 gallons of fresh water capacity plus storage for black and gray water if you get in a pinch. Try to travel with water tank full and storage tanks empty, you may not need a bunch of extra hoses.

I forgot to mention this, a few others have I believe, a surge/undervoltage protector. I have been camping only four years now but in that time this accessory has "warned me twice" not to say something would have happened but at least the thing did what it was supposed to do. Both times it was UNDERVOLTAGE which can cause problems. Two co-workers that are camp fiends have a motorhome and went out west. Their RV electrical was destroyed while staying at a park that had a damaged electrical. They ended up getting on board electrics replaced as well as some appliances that trip. After their sharing is when I bought this. I do NOT use it when on the generator.

Does Airstream supply hoses, cords, etc with new Airstreams? I know that some SOBs do. We have a new Camping World in my area. They provide to all NEW trailer RV buyers a kit that includes all necessary hoses and cords. Also in the kit is a bucket, sponge, soap, wax, black tank treatment and some other goodies. This all comes in a large Good Sam/Camping World tote. Of course not everything that will be needed but enough to get started with the basics.
The Airstream Dealer, Bates RV, gave me a kit when I purchased my AS. It will get you started but it is bare minimum 10ft of hose, etc. I was thankful it is just that I knew it would be soon replaced.

There are some campgrounds where the water pressure is so high that the freshwater hose will leak or burst. There is one place where we stay every year or two where the pressure is 100 PSI where that is the problem. They warn people and have pressure reducers for sale. I just fill the freshwater tank and use that instead.
