best thing, IMO at this point would be to
melt all the plastic down, and make a little card, stamp it and call it a "credit card rebuild" then use your new credit card to buy a new, different brand of pump.
you will be much happier and safer in the long run.
i would suggest either maxi, mag or aquaclear powerheads. for price and performance, these are all good powerheads amd worth the money
