City Water pressure regulator (location) leak?

Where is this regulator located in a 2009 28' International. We have a leak somewhere and have ruled out everything but this component, but can't find it.

Help!

According to the 2009 International Parts Book, the pressure regulator is incorporated into the city water hookup, part #601392-05. It's not a separate part.

Sinjin,

It should be just inside the trailer close to where the City Water connector is on the outside.

On my '76 Argosy, it is at the rear under the street side bed.

However, in redoing my plumbing it made more sense to relocate it outside before the fresh water hose. That way it not only protects the plumbing inside the trailer but the hose too!

I used the JABSCO 'Water Pressure Regulator' under their Model Number 44411-0045.

Good Luck!
Chris

It's all one part of the city water hookup.

Describe your leak. For example does it stop when the hot water heater is off. The reason I ask is this is a common problem of water pressure increasing in the water system by the thermal expansion of the water heating. If there is no air "bubble" in the top of the hot water heater to absorb some of this expansion it maybe forced out of the weakest fitting(s). This is especially true of the newer electric/propane combo units, probably due to a higher water temperature or the faster heating.

Yes, there is no leak when the water heater is off, or if the pressure caused by the heated water swell is relieved. I do not know if this happens when connected to city water. We have been running off the fresh water tank lately. Hmmm... Will this happen if connected to city water?

Another thing to consider is a small expansion tank. Just don't know where I would mount one.

Help!
How do you know you have a leak? Where is the water dripping From?

Have you looked thoroughly at the connections and valves on the toilet? That is a common place for small leaks.

Have you checked the connection on the outlet of the water pump?

Oh yea there is a leak! The dripping shows up on the street side forward and aft of the wheel well. For the final 'Here is the leak' we used dry toilet paper placed at several locations. And the winner, WET ONE was at the city water inlet connector. I was just able to place the TP there with the help of long arms and a pair of pliers. All other fittings were dry.

You are confusing me. Are two people with different user IDs posting about the same leak in the same trailer?

That's a bummer.
I'm guessing that if you detached the filler fitting on the outside of the trailer, you might find enough slack to pull it out far enough to access the back of it.

This WBCCI article from Airstream describes how to restore how to restore the "bubble" in your water heater to take up some of the thermal expansion in the water system.

Thanks Doug. I did not know how to create this air space in the tank. In essence making the water heater tank an accumulator too. It makes sense. Good information.

PS Brother in law had good walleye fishing on West over the holidays. I have no idea why anyone would want to ice fish?

One of our trailers has a built in regulator, one does not. On both trailers I use an adjustable regulator with a gauge hooked to the park water connection. Many parks in areas where it freezes use underground valves with an outlet and handle above ground. Many times these systems have loads of pressure. I want to protect not only my trailer, but my hose as well.

Works well everywhere for me.

David, this is a reason why, our granddaughter today in the fish house on West Battle. She's proud of her catch.
