city water intake fitting broke off

[Driver1]

Hi,

I've been using one of those 6" hose extensions with a spring around it to prevent it's kinking. The spring was too strong and while closing the outer cover of the area, it caused the city water intake fitting to break off. The line to that point seems to be about 5/8" thin walled brass. And, the line seems to emerge from a plastic part about 2.5 to 3" diameter but with a roughly square face to the outside.

Does anyone know what's inside there that will need to be replaced? What about how to do it?

This is on a 30' 1998 Excella 1000.

Thanks in advance for any help.

Hi again,

Hopefully someone's familiar with this and and can offer some help. My prior attempt at a word description seems to have failed, so I've taken a few pictures for clarity. Included are my city water hookup point, the part that broke off, & the extension I wish I hadn't used.

This is not a difficult job. You will need to remove the entire component/assembly. There is a small access hole on the side to get to the backside of the valve assembly. When you buy the new part, it is available with a water pressure regulator or not (your option) and it will come with a check valve built-in.

Hi Dwight,

Thanks for the response. When you say there's a small hole on the side, do you mean the side of the housing where the black tank backflush enters? How is the assembly attached to the water supply (Threaded, slip, soldered)? Where can I buy the new part and what's it called? I'll probably want to go with the water pressure regulator.

I did try removing the 4 screws in the assembly's face and pulled about a 0.25" until it felt like I might break something, so I can see there must be a rear access as you described.

Again, thanks Dwight.

Driver1, Dwight is right, it's not difficult to change. The water line on the inside is just finger tight, maybe a litte snuger connection. Once you access that and unscrew it simply remove the 4 screws and it's loose. I bought a replacement for my 1990 from PEXsupply,com You may find it elsewhere. My 1990 has the model with the built in pressure regulator. I'll bet yours does too. Airstream has used pressure regulators since forever. The part that seperates when they break is held together with very thin brass that is simply rolled around the fitting. On my 90 the thing is mounted on the outside skin. It's very vulnerable to breakage if someone walking by hits the hose. Since I replaced mine I've carried a spare. I should put a valve in the water line inside because if this thing breaks and you can't shut off the supply you could be without water till a repair part comes. There is supposed to be a check valve in the line also but those sometimes stick or don't work or leak. If it leaks when the intake is removed then the open line inside the trailer could create a mess. Good luck. Charlie E.

Driver 1,
I just looked again at your pictures. Your connection is below the floor level. Unless there is a cutout hole in the floor to reach down and access it you'll probably have to drill some rivets holding that little compartment on the belly wrap or cut a slit or two in the belly pan. I can't tell for sure from here in Maine, it's about 3,000 miles you know. Maybe you can drill out the rivets holding the hinge on the access door. Check it out. If Airstream put it together it should come apart. They don't hide their work that well but what you should be able to figure it out. Charlie E.

I had to replace mine about 6 years ago and the trailer isn't at the house for me to look at it, but the access area is the area for the black tank spray hose. It is tight and I didn't have to cut or make any extra holes to replace it. Just take your time and go easy.

Hi Dright & CharlieE,

Thanks for the coaching, I truly appreciate it. I'll have another look in the morning after the frost thaws.

Hi CharlieE,

I looked at www.PEXsupply,com and didn't find a part that seemed right. With a Google search, I did find the following. Is this the correct part?:

Shurflo RV City Water Entry Polar White
CDRV #26215
Mfg #183-029-18
Ship Wt: 0.626 LBS.

CD RV Parts Price! $36.02
Shurflo RV City Water Entry Polar White
Shurflo RV City Water Pressure Regulator
An exclusive diaphragm design prevents high-pressure damage often caused by city water systems. Leak-tight, stress and crack-resistant, these high-performance water entries limit water pressure safely to 50 PSI [3.4 BAR] or 65 PSI [4.5 BAR] while meeting or surpassing all check valve code requirements.

Driver!
That's the one. Glad to help. Charlie

Walt,

I just replaced mine yesterday!

There is a female threaded swivel fitting that screws into the back of the Shureflo.

Make sure you take the screws out of the hose spigot right next to the water inlet.

Good luck.

Hi Dright, CharlieE, & ArtStream,

Thanks to your coaching, the job's done. In our unit, I found that access to the back side of the City Water Entry assembly is somewhat different than what you've seen. The attached pictures highlight what I found. Once you have the access, the change-out is simple.

Hi Dwight,

You were right about how to get in there. Thanks.

Walt,
Nice job.

Next project:

Shell off, floor replacement

Don't know if you have room, but I use those brass 'quick-disconnect' hose fittings on all my fresh water hoses and connections.

I put one on the city water intake fitting and fit the matching fitting with a plug in it, into the intake while on the road to seal the connection from unwanted bugs, etc.

I carry an additional spare Q-D brass fitting to screw onto the water supply valve at the park when I'm hooking up...then it's simple to Q-D my hose to both the trailer and supply. I have several other spare hoses, so I can simply Q-D another if I need a longer length, etc.

I think there would be less 'strain' on that water inlet fitting on the trailer by just hooking and unhooking the pre-installed Q-D on the supply hose, as apposed to screwing/unscrewing a hose...or maybe you could permanently mount that 'spring' extension hose with some kind of rubber covered clamp - then put a Q-D fitting on the other end...to transfer the strain away from the valve assembly.

Hi Mexray,

I use one of those in-line filters before going into the trailer (It's blue & I forget the name). In any case, I'd like it to hang down a bit on something moderately flexible to reduce the chance of a bump breaking something like what did happen. Does anyone make a short (Maybe 4 to 6") hose stub without a spring (The spring on those I've seen is overkill by far)? The PEX itself in those I've seen seems more than adequate to avoid kinks (Especially if I have more than 40# of water pressure coming in).

I just made up my own hoses using brass garden hose end repair fittings...you can see them in the photos below...also the brass Q-d fittings I use.

I mounted some fittings, a valve and in-line water filter in a plastic tote box...

I also use the SewerSolution type sewer drain device that used a water jet to break up the solids and then drains through a one inch hose...works great!

I stow the whole set up in a larger plastic tote...all the hoses connect to themselves with the Q-D ends during storage.

Mexray,
That's a pretty cool little setup you've got there. Can you provide a quick parts list so I can make one???

[Mexray]

If you click on the pic of the tote box, it will enlarge so you can pretty much see the components I used...

Inlet side;
1. female garden hose adapter x 1/2 PT (pipe thread)
2. 1/2 PT three-way ball valve

LH branch:
1. 1/2 PT street ell
2. 1/2 PT x male garden hose adapter
3. water filter with garden hose threads
4. quick-disconnect female connector
5 garden hose to trailer inlet with Q-D fittings both ends.

RH branch;
1. 1/2 PT street ell
2. 1/2 PT anti-drain back valve (check valve)
3. 1/2 PT plastic pipe nipple - 10 inch, or to fit
4. 1/2 PT x male garden hose adapter
5. garden hose to sewer solution device with Q-D fittings on both ends.

You may need several 1/2 PT close nipples to attach garden hose adapters, depending on what type are available.

Use all brass components to avoid rust of iron pipe fittings.

Large hole in end of tot box for water filter so it can easily be replaced when needed.

hope that helps...I bought most of the fittings from Home Depot and Lowes...
