2008 Coachmen Freedom Express 21QB. I can hear it -- which is why I'm trying to find it. I'd like to try to silence it. I can hear it around/under the shower area, driver's side rear of the motorohome. But I'll be dogged if I can find an access panel.:h

Is this a class C with a basement storage area? Is it near the wheelwells? Many times I have found them near the tank, and that is under the floor in a outside basement compartment on my 97 Bounder by Fleetwood. My 72 Coachman camper it was near the water tank, under the same cover that you can lift to drain the tank, or check the water level. Many times it is under the dinette seat, but not in this case. If you have twin beds, try removing the mattress, then look for a removable plywood cover under the mattress.Look under the RV, you might see what compartment it is in?I found that by installing a accumulator tank, my water pump is much more quiet. Also flex lines - like found at the hardware store to hook up a 1/2" faucet to the shut off valve will work to take away the noise and vibration!You do not need to install the accumulator right next to the pump, though that is idea, it can be on another faucet, or a tee anyplace in the lines. If no space near the pump, then install a tee to the line going to your kitchen sink, and hook it up there. It will take out the surging pulses of water pressure that the pump is creating. So best when it is close to the pump as possible, but will work in a remote location too . . Have fun camping!Good luck!Fred.

What you are hearing is most likely not the pump. The pump itself is pretty quite. The noise usally comes from a flexible water line vibrating against a sounding board (wall panel, flooring, cabinet) as the water passes through it. Few manufacturers go through the extra expense of mounting and isolating water lines to keep them from vibrating agaist anything. Coachmen Express is bargain basement, water lines will be laying against whatever was there when they were pulled trough.

The pumps are usually quiet, what noise do you hear?

In my 2008 Winnebago OUtlook the pump is in the first bay on drivers side. That is where I access the valve to dump the fresh water tank and the pump is there next to the tank. Good luck in finding yours.

I have a 2008 21QB as well and the access for the pump is through the outside storage door at the back of the MH. Open the door and as you are looking in the storage area, you should notice a small panel on the left, about 6" x 10" held in place by a couple of screws. This gives you access to the pump, which is, in fact, under the shower. It is a PITA to get your hand in there to work on it. I did a mod where I put a faucet with a shower valve in the bathtub (I hated the shower hose connected to the sink faucet) and I had to cut a hole through the inside of the storage area, above the panel for the water pump, to gain access to under the shower. Nice to have small MH but they have to fit everything in a small space.

Another option might be to remove the water fill panel at the rear, but I would be careful. Good luck!

By the way, if you find it under the shower, how in the world are you going to get at it to:

- Quiet it via it's mounts or the piping around it?

- Repair it?

- Replace it?

- Remove it's filter to clean it?

- Get at the connections and piping around it should a leak ever develop?

Yep - double checked last night.
Nothing in the closet but furnace and water heater.

I'm now certain its somewhere ?under? the shower. I'm going to re-pull that access panel, already mentioned, and start digging. :)

It's now become a "Where's Waldo the Water Pump" game.

I have a 2007 Coachmen (different model). My water pump used to be REALLY loud - to the point I was embarrassed having to run water at night for fear we were waking the campground! I have a similar rear corner bed layout in the back, and the pump is accessed by removing the lower drawer in the cupboards just forward of the bathroom. I'm guessing you've already looked there if you have a similar drawer, but thought I'd offer the suggestion.

I got pipe insulation (the foam stuff that has tape pre-stuck to the seam) and slid it as far along the pipes as I could from my access at the pump to eliminate the pipes vibrating against things. It helped, but ultimately putting a new quieter pump (one with a variable speed motor) helped even more. Now the old pump is onboard as an emergency backup (to be replaced ASAP if ever needed).

I've removed about every panel I can find... Except the one that hides the pump. :)

The Fresh Water Tank is passenger's side above, mounted on a platform above the wheel well. I can access the tank by removing the forward panel in the large baggage compartment.

I agree the sound seems to be coming from the shower area. I did remove the small panel, bottom left of shower and saw nothing. Just the shower panel.

Nothing under the bathroom sink that I can see. I removed the toilet paper holder and peered down. Nuttin.

Mine jack-hammers too. Loud enough that I worry about bothering a neighbor at an RV park or waking someone up. :)

Toilet is not on a pedestal.

I'll keep looking.

once you find the water tank you can look in that area for your pump. they are not very far from the tank. closer the better for suction purposes.

Looking at the layout and pictures of this unit online, I would guess the pump is either in the pedestal under the sink or else accessed from the big storage compartment under the bed. (Is there an access panel towards the bathroom area there? or maybe the entire wall comes off?)

Maybe you can locate it a bit more precisely from the smallish access panel next to the license plate—which I assume is the sewage compartment by a process of elimination, but you'd obviously be in a far better way to know that I would.e

My Coachmen has it next to the fresh water tank in the base of the queen bed, but that's obviously not the case for you since the base of the queen bed is basically the big basement storage compartment.

the best way to find out if the water sys has a small leak is with the pump...take it from some one who knows and it saved me a ton of money if I had not discovered the leak under the shower by hearing the pump cycle on and off due to the leak.
