air in pump

[Barry J]

I believe I fixed the leak with some teflon tape...but, my return hose does some vibrating which cause that fountain to vibrqate...any reason why my return hose vibrates...is it too long maybe???

Barry,
One possibility with the vibrating hose is it could be resonating. Everything that can flex will have some natural frequency and normal water flow through a flexible hose can start and maintain oscillation. If there is no air coming out of the return I would guess this to be the case. A resonance would cause it to vibrate at one frequency and the vibration would be regular and not erratic. If it isn't vibrating enough to cause a problem like eventual fatigue of a joint then I'd just live with it. Shortening the hose may help. Best I can do for now.
