RC makes a good point - since the Eco7 is low cost, have a second one on the self as a 'back-up'.
That's exactly what I meant, if aeration is critical in your pond having a back-up really makes sense. If it's not rebuildable then it's disposable, that doesn't make it a bad pump.
My pump runs 24-7 from Nov.-April, and during the summer it runs at night being connected to a thermostat.
It's a matter of application , my pond is maximum of 8 ft. so the linear pump works fine for me, if my pond was deep and larger I would probably use a Gast style.
