Mp 10 problem

[rocksteveo]

I have a brand new mp 10 and in having issues with the pump staying put on glass, its not falling off but every couple days it starts spinning. The glass is. 3/8 thick, not sure what the deal is,

Don't use the rubber coupler/pad that comes with it. If you aren't using it, then it sounds like vibration is turning it? Are you sure it is aligned properly?

Im not using pad, and im pretty sure its alligned properly, i have 2 mp 40 as well and had no problem, its weird i set it the a few days later its just spinning in place

Hit up Dave at Concept Aquatics. I'm sure it's a warranty issue.

Have you checked the spacer on the back to make its set tothe right glass width? Mine did the same thing, just had to adjust.

I dont think the mp 10 has adjustable spacers on the, my mp 40 does

[Coralgurl]

Yep, you are right, I just checked mine. Mine did spin off as well, sounded like a jet plane in the tank, but it's been fine for a few months now.

What glass thickness do you have

Rock, I had the same issue with an MP10
If you get a wetside that isn't 100% it will spin due to vibration
If it's bothering you enough, take the wetside back and try to get one that doesn't go 'ch ch ch' when you spin the prop
