Water pump problem

[lacamastraveler]

I previously posted this on the Mercedes Benz Sprinter site but am looking for as much input as possible so I can discuss with my tech when I return to Bend, Oregon.

Suddenly I am getting very low water pressure from my water pump. Was working great earlier then discovered the problem later in the day. It affects all faucets and toilet so has to be in the system. I've had the RV for 18 months and do a lot of dry camping so doubt it is manufacturing debris in tank as one person experienced.

Not a problem now because I'm at an RV park and will be until I return to Bend on Friday.

Any previous solutions will be much appreciated. Thanks.

Have you checked the water pump inlet filter/screen?

Does it start out strong and then drops off after a few seconds? If so then I suspect the inlet screen also. If it never builds pressure then it could be the pressure switch/transducer in the pump.

5 picker and Bama, that's great. No, I haven't and it does exactly as you said Bama. Now I just have to find it and maybe save myself a service call. Thanks!

The inlet screen usually screws right into the side of the pump.
Here is a video that might help.

And if you've got those brass valves like the guy in the video, you may want to purchase some new valves. The brass ones are JUNK.
