tackling the H2O system this fall

A goal I have this fall is to work on my on board water to quiet the pump down. I've read on doing the various things to make the pump a little more quiet. One obvious thing I see is that the line coming up from the tank was cut a little short and it's touching the floor where it comes into the trailer. It's actually almost crushed there it's so tight so I'll be adding an extension onto that line and isolating the pump from the floor. My question involves adding an accumulator so the pump doesn't cycle as often and from time to time during the winter we get temp fluctuations in the shower when the pump cycles so I'm trying to cut down on that. I realize it will depend on the amount of room I have which is actually quite a bit but what is a good size to look at? I'm not sure what the minimum should be. I've found the $40 shur-flo designed specifically for RV's. Good enough? Better bigger one out there I should look at?
  • Anyone use a tank with a variable speed pump? Directions say not to, but I can't understand why.
  • I won't have the 5th wheel back here at the house until fall. I've left it out of state at a friends place too save on fuel costs this summer since everywhere we've went this year goes out that way. Saved us about $450 in fuel this summer....that's nothing to sneeze at. :D
  • Why wait till fall? It took me a leisurely afternoon to install an accumulator, and I am not very good with my hands. (I do a lot of handyman stuff, but not very well -- fumble fingers.) I would say to install the biggest accumulator that you can. In my case, that was a quart size -- I have almost no room next to my pump. Even so, the accumulator made a huge immediate difference in the noise.

    Putting 1/2" flex hoses on the pump input and output can make it very quiet, and also solves your short line problem at the same time. Look for the flex lines at your local hardware store, near the bathroom fixtures.

    ALso a 1 quart expansion tank will keep the pump from cycling as much, and smooth out the pressure, making it very quiet.

    X2 on the hoses. I did that to mine and I can hardly hear the pump running. Also made sure that the hoses are not touching anywhere in the cabinet. JMO
