Water Pump Question
I purchased a 1999 AS Excella 31’ travel trailer a couple of years ago and have been slowly working on it for my retirement. It’s in good condition, and most of the stuff works. I’ve recently been focusing on the plumbing fixing leaks and other issues. When I connected a water supply to it, I get water to all areas. After filling the freshwater tank, I removed the other source and turned on the pump. I can hear the pump running, but there’s no water being fed to the interior faucets. I feel the problem is the pump, but not sure. Is there a switch to go from hose to tank supply? Anyone had this issue?

I would guess your pump has lost its prime or the strainer cap is leaking. You can kill two birds with one stone. Remove the strainer cap and make sure the o ring under the cap is there and in good shape. While you have the cap off, pour a little water in the strainer to prime it, then replace the cap. I also find it helpful to open a faucet when turning on the pump after the water system has been dry.

No switch, you can run the pump with city water if the city pressure is low.
Your pump might not be able to self prime, a sign of an aging pump. There also might be a valve between the tank and the pump, sometimes installed as part of a winterizing kit.

Replace the pump. Replace the strainer. Use the silencer kit. Add an accumulator.

I replaced the pump and strainer. The system works now. I plan to order the silencer kit and the accumulator. Do these additions fix the vibration issue that happens as the system builds pressure after shutting off the faucets? Or do I have a new issue?

Silencer kit will reduce the vibrations but not necessarily eliminate them. Accumulator will reduce cycling or throbbing when using a trickle of water.

Thank you again. I’ll get and install those items, and keep you posted.

Also, watch the hoses to/from the pump when it's running, since you have things already opened up. Often the pump vibrations are transferred to those hoses, and if they're tapping against anything, there's another source of noise. Hardware-store pipe insulation (I've heard of using pool noodles, also, but they're not as soft) on those contact points will go a long way to silencing noise.

I’ll pay attention to that. Thank you.
