Aquajet water pump questions

[Pappy]

I have read there is an adjustment on the Aquajet water pump. Is the adjustment the hex screw on the pressure sensor where the wires come out of the head or is the adjustment located where the spring is located under the cap?

This pump has been noisy from day one even after you get the air out.
Mine has a flex line on the output side only and the rubber feet are not compressed or to lose. But after reading all the fixes via the threads it just appears to be a noisy pump and not from the lines . I have just been living with it but on my last trip it all but quit and was making some noises that were not healthy dead cat sounds and output pressure was way down eventually it recovered to its old noisy self. Plenty of water and proper voltage.

I took the diaphram apart to see if it was contaminated but it wasn't. I did notice that wiping on the little black valves caused lots of black to be removed from the valves. Which would appear to be deteriorating. That should not occur on a 4 year old pump. Thats not good especially if its contaminating the drinking water. Anyone else took a look at this?

And finally can anyone comment on just how this thing functions. The shaft from the motor goes to a metal connection that is offset. I am assuming this is correct and that it causes sort of a concentric warbling action and thats how the pump achieves the pump action??? And probably the reason its so noisy.

I will call Aquajet on Monday but I was just wondering if anyone else had any comments.

Called factory today here is what I found out.

No mechanically pressure adjustments on my ES AES model only electrically can it be changed via the circuit board under the bottom plate not recommended. All red plastic pistons have T's on them the top should be facing inward mine are.
Ask if motor was smooth without pump attached mine is.
Ask if any leakage between pump and motor mine was dry.

Tech says its hard to get them quite in an Airstream??

I put rubber pad under mine today and flex line on input some improvement but not satisfactory.

I agree.

These pumps are ridiculously noisy. (Unacceptable. Anyone using the facilities at night wakens everyone else sleeping in the trailer.)

I would gladly replace the pump with a different one but I am only just starting to research which type of pump would be quieter & reliable.

Hi Evan -- it was cool having side-by-side 25' FBs at Waterton Lakes. Gosh, that was only last month! Well, early last month...

At a later September camp outing, our OEM Aquajet was unresponsive when we turned it on. It would finally succeed after we cycled the switch 2-3 times. I couldn't complete winterizing today because it is now DOA. That's not a heartbreak - some feel the OEM pumps don't last that well.

I always had some quiet pump threads tagged. I'm going with the Shurflo.

Hi Bob,

Yes it was very nice to meet you in person.

We rarely encounter other Airstreams let alone almost identical units parked side by each. What are the odds?

It sure can blow there. (Upper Waterton Lake - Mt. Cleveland in background in Glacier NP, Montana.)


I'm sorry we didn't talk again before you pulled up stakes. We headed out one morning for an all-day hike ( I think it was the morning after all those Yahoos were outside making noise in the dead of night) & then found you gone when we returned. The lake calmed down after you left. It was a pretty nice change.

We headed out a few days later at dawn. We'd like to go back as we saw a lot of wild life when we were there. (That is besides the local party types.)

To stay on topic though...

Sorry to hear about your pump. It could have at least had the decency to wait until you finished winterizing.

Ours still works but I have to say that I will probably replace ours anyways. The noise & shuddering flow it produces is pretty bad. I have ordered an accumulator but will probably also get one of the Shur-flo Extreme 4.0 pumps to finish it up. Please let us know what you think of yours.

OK. I broke down & ordered one of the Shurflow Extreme 4.0's as well.

The stock pump is just unacceptable. I'm not going to wait for it to fail. It will go into the spare parts box.
