Noisy pump? Check this out.
So my 04 22' ccd has had a noisy water pump or its probably just normal pump loudness. Probably one of my biggest beefs with the airstream. I decided to install an accumulator so the pump does not come on all the time. Installing that helped a bit. But was still not acceptable. So i decided to tear it all apart and start fresh. Here is the line going to the pump as installed by the geniuses at airstream. You will notice 5, 90 degree elbows which i replaced with 1 flexible line. Also after the accumulator i installed another flexible line outputting to all fixtures. Vast improvement. The accumumlator now works much better as i can run my tap for about 5 seconds before the pump will even come on. Might try this if your airstream pump noise is not to what i think should be airstream standards.
Enclosed for your viewing pleasure.

The els were probably needed to go around the square column holding the roof over the pump!!!! HA! HA! Not to make lightly of the whole thing.

That's where the assembler was kneeling while plumbing the water pump. He had to get around the spot where he was kneeling.

lol. Those pesky knees get in the way every time. A guy with an IQ could have run a straight pipe behind the waterpump bracket with one 90, up to the pump. Unbelievable. Its a good thing it happened though cause otherwise what would one talk about?
David. No i dont have a pic but i guess i could pull off the panel and take one.

And I believe that the manufacturer of the pump actually RECOMMENDS flexible lines instead of rigid! We installed flexible lines and it makes quite a difference - so does putting a rubber pad or bushing between the pump and the wooden floor - I used an old mouse pad.

While we're talking about water pumps.......
That looks like a great improvement to the water pump.
I have been having a problem with my pump and instead of starting a new thread, I will tag on here - I have a 1992 Excella. When I run water, SOMETIMES the pump will not stop running. I can usually get it to stop by running the cold water at the kitchen or bathroom and a bunch of air comes out - then the pump sound swells to really loud and finally it shuts off. WHAT IS UP WITH THIS???? There is water in the tank - could it be that the intake hose isn't far enough into the fresh tank?
I keep trying to think about what it could be - thought I'd ask the experts. I have NOT examined the pump itself - only owned the trailer for 2 weeks and still learning.
I DID, however, have a problem yesterday - all of a sudden (like within minutes), the bathroom sink would give only a trickle of water. Everything else was running with great water pressure. I took off the screen/bubbler thing under the tap and it was full of something that looked like broken shells and sand....I cleaned that out and all is well now.
Could that have been the pump problem?

Sounds like air is getting into the intake. The pump wont compress air. May be a loose connection between the fresh water tank and the pump.

How about replacing your current pump with shurflow variable pump, which is lot quieter than the factory installed. I baught one for $129 and the change over was very simple in my 20 footer under the oven.

The bearings in my original Aquajet pump seized up. The pump had always been extremely noisy since we bought the trailer - and for all the racket it made, didn't put out a whole lot of H2O.
When I removed the pump I order to diagnose the problem, I found that it had a loop of flex hose in the outlet side, but hard piping right up the inlet filter - contary to Aquajet's installation instructions.
After I found the problem with the pump (seized bearing) I emailed Aquajet to see if I could buy parts. Two emails - no replies.
I then decided to just buy a new pump. Local RV dealers only had Shurflo in stock so that was what I wound up with - rated flow slightly less than the Aquatec Spec. I installed wit flex hoses on both sides of the pump.
The new pump works a treat! Almost silent and greater water flow than we ever had with the old one - all's well that ends well.
Brian.

I think you have a leak on the suction side of the pump. If there are rubber hoses connecting the tank to the inline filter and then to the pump; they could be old and dry allowing air to etiher get in at the fittings or simply through the hose wall.
Replace any and all hoses on the intake side of the pump making sure that the connections are tight.

Got to find the pump.
OK, I'm going to try to locate the pump - I think it is in the closet under the floor (of the closet). That is where I hear it all the time. I'll see what I can find and let you know what I see (or take a picture). Thanks!

Mine made noise too. But it was the pump moving the pex pipe I put in. Even though it was tied with pipe brackets. I bought some of the foam pipe insulation. Put it in the bad spots and now it's nice and quite again..

Found the pump - picture here
OK, I found the pump - the far (in the picture) hose fitting seems a bit loose but when I try to tighten it the whole pipe system, elbow, etc. moves....

It is a Shurflo pump - not sure what the thing on the right is.
