Technical Support / Re: Air hose/tank fittings

Bill, What your looking at is a compression air brake fitting that somebody has over tightened, that blue ring is the air line that the ferrel has cut into.
Remove the elbow and figure out what size you need, most truck shops will have air brake fittings not many auto parts stores will have this type of fitting. If you know the size you can get them from amazon or many other suppliers on the web.
Just make sure that what you replace this with is a "dot brass air brake fitting".
You can get brass compression fittings at hardware and home stores but those are not approved for air brake systems, so don't go there.

That is a "air line compression fitting". The brass "band" is what does the sealing. Usually they are smooth (like a wedding ring).

My coach was built with the "Push-To-Connect" style fittings. These are great for assembly line work but not so good for coach owners (they always leak and are hard to impossible to get the line out of for replacement). When I come across a leaking PTC fitting, I replace it with a standard "Air Brake Compression fitting. I just cutoff the nylon air line at the fitting - as most of the time you cant get the old line out of the old PTC fitting.

The most common sizes on our motor coaches are 5/8", 1/2", 3/8" and 1/4". Your photo looks like the line is for the tank drain, so 1/4 inch air line (with 1/4 inch NPT threads going into the tank) is most likely what you have there.

Remove the 90  elbow and take to Napa Auto/Truck parts store. Probably 5/8 threads 1/2" air hose slip on for the air line. Hopefully enough air line to cut the end off and slip into the new.

I have an air leak in the hose connection coming out of my air tank on my 1998 Patriot.  The picture below shows the fitting.  Not in the picture is the nut that goes over the fitting that threads to the open connection on the tank shown in the background.  Does anyone know what this fitting is called?  I'm thinking the leak is caused by the flat blue o-ring seal hardening from age and no longer sealing.  Does anyone know where to get replacement seals?

Greetings! I currently use what you mentioned, buffering seems to only be a problem during "high traffic" times in the evening. If I use Neflix stand alone app, I get far less buffering then going through Dish Network. Good luck.

We have the same coach. The Hydro Hot is the same thing as an Aqua Hot. Vehicle Systems, the manufacturer, changed the name a few years back to sound fancier. Other than that, and the size of the tank, they are the same components, and system.

If you are not familiar with how it operates, there are some good pictures with flow charts on the website, We have had our Monterey for 8 years, and it has been the single steepest learning curve, among many.

Even if you don't use it like a full timer, it should be serviced once a year by yourself when you become an expert, or a certified aqua hot tech. Especially, change the nozzle, change the diesel fuel filter, and clean the combustion chamber.

To access the inside of the metal box (it has a double hinged lid) get on your hands and knees and look under the bay door. You should see two black rubber plugs. Pry them off, and use a long phillips screw driver to un-screw the screws holding the lid down. Over time, when its time to put them back on, you will learn to use a magnetized screw driver to hold the screws in place while you stick the screw driver back through the holes under the bay door.

Bill Sprague is absolutely right. You must winterize if you are going to store the coach in cold weather. Temporarily in cold weather is okay if the ambient temps rise above freezing during the day. Your coach has a thermostat that will provide heat to your water bay, and the aqua hot components when the temperature gets below a pre-set threshold, usually around 43 degrees F. For it to kick on, the diesel burn switch under the kitchen counter must be on.

Good luck. Its an awesome system once you learn it relatively well.

We had a '04 Monterey for a dozen years.  I got to know the HydroHot quite well!  We loved our Monterey in every way but one and it was the HydroHot.  When it worked it was spectacular.  It even kept us toasty in a South Dakota blizzard with below zero temperatures.   When it broke, it was always confusing and sometimes expensive.   

If you are new to Hydro/AquaHots and ever near cold weather, be sure you know how to winterize it.  If it ever freezes, the cost to you will be HUGE.

There are three pumps in there.   Two circulate the heated coolant to the radiators throughout the rig.  One does the front and one does the back.  Both have check valves that point straight up from the pump and go vertically outside the box.   In normal operation, both of the tubes coming out of the box should feel hot.   

The third pump is called the stir pump.  It is on the right.  The HydroHot is a smaller version of the AquaHot and needs the stir pump to circulate the coolant in the tank for consistent hot water.  It has an odd magnetic drive that gradually fails over time.   It is very hard to trouble shoot because the magnetic drive can keep it "stirring" but only marginally.  If hot water is inconsistent, suspect the stir pump.

     Fred, After reading your response, go ahead and lower the room 1/16 to 1/8" and see what happens. The way the room was originally engineered is: when the room extends the top horizontal seal engages first and then the bottom finishes extending. Like wise when the room retracts, the top always seals first and then the bottom draws in last. This is so the top seal always engages first to keep water out. Let me know how it works out. Fred

The Aqua Hot (or Hydro Hot) is the grey box in one of the basement bays. Most have a couple of screws holding the cover on. Some coaches have access holes for the 2 screws at the bottom of the cover.
Here is the Aqua Hot Manual library.  Download the Service and Owner manuals for your model.
If one hose is hot and the other cold while the thermostats are calling for heat, probably that check valve is stuck, the stir pump (round shiny unit) is not getting 12v or the pump has failed as Gerald noted in his post.
