Water pump

[Dogwoman]

I recently replaced my water pump. It's always made some noise, but it's now shaking so violently it sounds like it going to come off of the platform! Recommendations are needed! Thanks.

could be lots of things. You don't say what you replaced it with, why, etc...
could be loose. Could be plumbed wrong. Did you do the work yourself?

Not seeing it or knowing anything really about it, My bet is air. Check all your fittings on the suction side especially. Sucking in air will make it rough and noisy. Check the strainer cap, and all the fittings back to the tank. Might need to take them apart and re-do everything to find it.

Maybe attach some pictures, might help us come up with ideas
