Pressure tank on domestic water

I would expect that with the pressure tank the pump should not be running immediately, but it starts the instant the water is turned on.  Is there a fix for this or am I expecting to much?

The pump should run intermittently. I just went out and read the air pressure on our blue tank.  It was 44.5 psi.  When properly pressurized your pump will only turn on when the water level in the blue tank reaches a certain level.

The fix is easy.  Use your on-board air hose to add air to the tank.  Just unscrew the black cap and add air pressure until you reach 44psi.  My psi could be different than yours.  It would be helpful for you to tell us the year and model of your Foretravel.

Just think, this is one fix you can make without paying someone $110 to $125/hour.

This is how our 1999 U320 works. I assume there is no pressure tank

(accumulator?)

Our 1997 U295 worked with a pressure tank as you suggest. best, paul

Note to old_nodaker

In re-reading your post I noticed that you said you were on domestic water.  If you are using "city water" your pump should not come on at all.  But if you are connected to "city water" and you have your Pump switch turned ON, then it will pump water from your water tank. 

My answer applies to our 320 only.  Your coach might be configured differently.

It would be real helpful to others to let us know the year and model of your Foretravel.  But, if your coach has a blue tank next to the pump I am pretty sure the pump does not run continuously.

George, you are right but the pump will run if you try to fill the tank and leave it on.  Also, if you have it on without it being plumbed in to the accumulator tank. I have seen that too on coaches. Why it was not removed, I didn't know but they put in a sureflow and left the blue tank and plumbed around it.

Open up the bay and follow the lines. The pump should run off and on as the pressure drops as stated above. If you are on the tank water and sitting still with nothing open, you leave your pump on and you hear it running but you are not running the water (ck the icemaker and make sure it has the bar lifted) then you may have a air or water leak. Other than that most FT are plumbed with the blue accumulator tank for a residential feel to the water pressure.

Okay, guess I need to figure out how to do the footnote for the pertinent data.  I've been going through life here thinking they were all the same!!!  You've answered my question, the only thing I wasn't sure about was if I had to drain the tank first.  In the olden days they would get waterlogged and have to be drained.  I assume these new ones have a bladder in them to prevent that.

On my '96 U-320 I discoveres the accumulator tank bladder had worn out by pushing on the air valve and having water come out. My pump went on every time I called for water. I had to replace the accumulator tank, it was an easy & simple job.

No need to drain.  And yes there is a bladder.

No "olden days" here[?]

So -- what have you got for us next?

It is good to see you here.  You've got a great motorhome

I had to replace mine last year (I think) with a new accumulator tank that I purchased at Home Depot or Lowes'.

Seems to work fairly well but, not as well as I had expected.  I draw off  1 1/2 cups of water and the pump kicks in to re-pressurize the system.

It is not to difficult of a job if you have long arms and can work by feel.........
