Vortech MP40 failure

[Big_Pun]

I've had 4 mp's and no problems except for wet sides. and that was stuff that was my fault or an anemone or fish going into one and messing stuff up. I had a used one that who knows how old the wet side was that seized up and broke the frame but again if i would have rebuilt it with fresh parts it wouldn't have happened. other than that I have had no major problems and I keep rebuild kits and ceramic bearings on hand just incase. if you heard a high pitch sound the dry side may have gotten wet and bearings internally failed I had this happen and as soon as I heard the sound i sprayed wd-40 and it went away and has not come back.
