Quieting the Water Pump

When we are camping without hookups I have noticed that our water pump is one of the few sources of noise. Today I installed a SHURflo 182-200 Pre-Pressurized Accumulator Tank and a SHURflo 94-591-01 Pump Silencing Kit.

In the original installation the pump outlet was connected to the water system with solid piping which seemed to amplify the sound of the pump. Whenever a tap was opened even a little bit the pump switched on then off again.

The combination of an accumulator and flexible hoses has reduced the noise considerably and the pump cycles much less frequently.

Not an expensive modification, easy to do and well worth while. High resolution version here: http://www.flickr.com/photos/brian_v...5765/lightbox/

Brian,
A few trips ago, I added the SHURflo accumulator and have noticed yellow water. The water in my tank is clear but what comes out of the tap (through the accumulator) is slightly yellow. Have you noticed discolored water?
And I too, appreciate the pump not cycling as much.

Ben

I have not noticed that. Our fresh water tank was empty and the whole water system had been drained from our last trip, then I partly filled our fresh water tank with clean water, and the water that came from the tank was also clean.

You might try draining your whole water system and trying again. There should be a low level drain on the driver side of your trailer for the water piping and also a drain for the fresh water tank. You may need to open the pressure relief valve on your hot water tank and open all water taps to get all the water out.

I did the same thing early last year, and even added more cushioning under the pump. Much quieter now. I also find that after the pump is turned off, we can get a few flushes of the toilet with the pressure accumulated in the system, which is nice for nighttime quiet.

I have had no issue with yellowing of water, and highly suspect it would be something other than the accumulator tank.

We added one to our Scamp and never had any problems with water turning yellow. One of these days I am going to put one in Blue too.

Jim:

Did you use the method shown here in post #25 to cushion the pump? Silencing the Escape 19 Water Pump

Pretty much, Brian. I got my idea from that post of Dougs. Here are the photos of my installation.
Winterizing question and unknown hose hookup

That's disappointing. The ShurFlo installation instructions that I have read clearly call for flexible hose, not direct connection of rigid tubing. Brian, did you ask Reace why hose wasn't used?

Is everyone's pump installed this way? Mine is in my current motorhome (despite the manufacturer's excessive use of hose elsewhere), but I had hoped for better from Escape.

My understanding is that Escape used to hook directly to rigid tubing for the outflow (like in my '09), but now doesn't. (Don't know when the switch occurred. And you're right, Brian, the pump manual specifically recommends against hooking to rigid tubing. I switched over a couple of years ago. Well worth it for quiet and pump life.

Thanks Bruce.
