I LOVE mine. An amazing piece of equipment. It has never need re-calibrated...though I've done it anyway.

You guys are costing me money...

It is rather amazing to watch a organism create that much rock from seawater. That's 30 pounds of calcium and Mg it's absorbed over 5 years of growth.

Any of those pumps could probably be cleaned and new brushes and starting capacitor exchanged. If the pump isn't sealed permanently. A motor repair shop would do it for very little expense.

what brushes and starting capacitors are you guys talking about?
the mag drive pumps are electromagnet drives.
There are no brushes, it is simply a coil of copper wire wrapped around a magnet whose polarity flips in accordance with the cycle of ac current.
If it gets too hot and melts the insulation around the copper wire that comprises the coils it will short out and stop working.
In theory, they should work indefinitely as there are no "moving parts" to wear out in the motor block.
and they are permanently sealed. the whole mess is encased in epoxy, that's why they are waterproof.
the lifeguard and similar external direct drive pumps have brushes and capacitors, but they also pull a LOT more electricity and generate much greater head pressure.
I was discussing conventional pumps that cost more than $100, not immersed ones. As Dary mentioned the impellers get accumulated calcium in them. Polishing the magnet on the impeller with some fine grit sandpaper, then wiping it very clean can sometimes bring them back.
