Boondockers and other folks who get away from "city water" connections sometimes complain of a noise when using the RV water system. Sometimes they're just not used to the additional noise produced by the RV's water pump; at other times there are problems--most of which are easily cured.
For "demand" water pump systems--those in use on nearly all RVs built in the last couple of decades--pull water from the storage tank and pump it through the inside lines. While designed with sound reducing isolation pads, sometimes these little "feet" can get away, or even a mooring screw can loosen up, causing undue vibration.
Locate your RV water pump and first ensure that it's firmly tight to the bulkhead or deck. If a screw (or screws) is loose, retighten. If the noise persists, double check to ensure that rubber isolation feet are under each contact point of the pump--and replace any missing parts.
At times, water systems that make noise can be quieted with the addition of an accumulator tank. The accumulator is nothing more than a simple reservior with a cushion of air. When the water pump operates, it pushes up water pressure against that cushion, often reducing the number of "off-on" pump cyclings and evening out the water pressure flow. Accumulators are fairly easy to install, and cost about 40 bucks. Camping World carries one on their website.

I have a 2 gal. water container I keep along side the john . Turn the pump off at night and use warer from that jug. In the wake hours it don,t bother use.

You forgot to mention vibrating lines.In the bathroom the water line vibrate below the floor of the cabinet.
Any comments on that?
Many times, the vibration noise is caused by the location that the RV manufacturer mounted the pump. If it's mounted to a "thin" wall, nothing you do is going to quiet it. Look for a more solid location near-by, and with a minimal amount of new tubing, re-mount the pump.
Our water pump was noisy - sounded like the engine brake on a diesel semi rig going downhill!
Bought a new pump from Camping World billed as "the quiestest" and it was a huge improvment.
I thought about adding an accumulator but if you do remember it is there when it is time to winterize. You'll either have to use more antifreeze or take it out for the winter and keep the accumulator somewhere above freezing. Since we now winterize by blowing out the water lines (didn't like the pink stuff - even if they say it is safe to use.) I'll be removing the accumulator every time I winterize.
Place your old computer mouse pad under the water pump reattach it.. and ahhhh golden silence.
I reduced my noise by placing styrofoam pipe wraps on the pipes close to the walls and securing them with plastic tiewraps. Result: no noise
I don't mind the noise, let's me know when my grandkids left the outside shower on or the bathroom faucet leaking!
Most water pump noise is caused by cavitation until the pump clears air in the system, it will then quiet right down. Make sure you bleed your water heater of air in the spring(open the relief valve a little while if is filling), it will reduce the time required to clear the lines of air and quiet the pump.
I installed a Shurflo Whisper King in my rig some years ago. Although the Whisper King was a lot quiter than the previous pump, it still was noisier than I wanted it to be.
I solved my noise problem by placing a remnant piece of doghouse (engine compartment between driver in passenger in gas rigs) insulation that was leftover from my doghouse insulation improvement project. I placed the 1" thick piece of insulation under the pump.
In addition, I took an old 1/2" white, potable water hose that I no longer used and cut two 3' lengths off of it. Don't buy that expensive braided-vinyl stuff that HD sells. It is not only expensive, but too stiff and will transfer any pulsing vibrations down the water delivery line. Buying a short (white, blue stripe) potable water hose at an RV supply store is a lot cheaper and the hose resists kinking a lot better! I placed 3' sections on each end of the water pump (suction and pressure sides). The extra footage nests quite nicely within the fresh water compartment. Be sure to coil the extra length without any kinks. The added hose sections act like a poor man's water accumulator and really smooth out the water flow at the kitchen sink or the closest delivery point to your pump. In my situation, it alleviated the pulsing that we normally got at that point of the water delivery system inside the rig.
With the piece of insulation under the pump and the added footage of hose, the pump literally cannot be heard inside the rig and can be barely heard next to the fresh water compartment door outside the rig!
Hope this helps...
Its not noise its NOISE way too loud for a new RV 2011 and its so noise ya like a big truck its really terrible!

As for the pipes making the noise,there are two things you can do.
1) make sure the water lines are not on contact with anything ( such as a cabinet or shelf)
2) put a small loop of softer water line between the pump and the water lines.
The loop will soften the vibration and some water hammering and will help quite down the pump.
I unscrewed my pump from the wood "sounding board" that the manufacture had mounted it to and suspended it with nylon cords so it just dangles in mid air. In one rig, I used the horizontal sink drain pipe for support. In another, I installed a cup hook in the roof of the compartment. I cannot even hear it run from across the room.
The water is being outfit from underneath the ground utilizing an engine that turns a sharp edge. This cutting edge makes a weight that pulls that water through the channels so that the required water supply is given. Much the same as in your home, water is streaming to your bathrooms, kitchen, and greenery enclosure to give you the water that you require. Some water pumps are covered underground while some are submerged in the water, as inside a well.
