Water pulsating

2012 Bighorn 3170

New to me and just de-winterized the water system.

Filled the water tank and turn on pump.

No leaks, (yet) but when you turn the cold water on the, the water lines starts pulsating. I pulled the panel and you can see the lined moving back and forth.
Any ideas.

Thanks
Tom

Could be air in the lines compressing and relaxing with pump pulses, bouncing the lines....Bleed all water orfices and see if it clears up.

While hooked to city water bleed all the lines and especially make sure the water heater is filled. Shut everything down and disconnect the city water then turn on the pump and see what happens.
