More good news - I cleaned all the damaged pieces of magnet off the main magnet and put the pump back together and switched it on with no hose attached and it worked. I'm not sure how long it will run like this.

I recirculated the system for about 10 minutes and all seems to be working well. The level in the tank stays the same. However, the level was down to start with so I topped up the tank with a hose and it went right back down to where it was.....confused

Another thing, the return comes back into the tank through my spray bar....this thing sounds like a huge waterfall, I couldn't hear my wife talking (not always a bad thing I know

That broken shaft will wobble enough to take out the motor case...The field is sealed in an EPOXY filled housing, the wobble of the impeller WILL wear through to the wiring (110vt/220vt)
Just a heads up, do not run it too long...~B

I have just taken it apart again. The screws look new, so I can't tell if it is an old returned pump or not.
Inside the pump, where the shaft sits has a few small scratches on it, I guess from where the broken pieces of magnet where scratching on the first start up. I'm sending you a PM now

This is because that is the level of the overflows. The water you topped off with is now in the sump...to change the water level in the tank you must raise the level of the actual drains...

even though noise has it's benefits... so does quiet...when you raise the overflow levels the water will be closer to the spray bar. I run spray bars just under the surface of the water line so I get the agitation and brake up the surface water but not the forever sprayer noise...~B

I'm still a little confused. The water level was over 1 inch above the drains when it was recircing. What would happen if I had my drains in the bottom of the tank??

Yeah, I guess I will to replumb my spray bar so that it is closer to the surface.....this is a simple job.

Big mess with out a standpipe...
remember this is overflow system...the only water you want to drain from the tank is the amount of water you pump there from the sump (filtered)
The "drains" are actually the overflows. So when the power is shut off, for what ever reason, the water level will only drop down to the top of the overflows. This keeps the sump from overfilling and draining the tank to nothing.

When my tank is full of water the top of the 2 stand pipes are about 1.5 inches below the water surface, but as soon as the system is running the level drops about .5 inch.

Hmmmm mine raises when I turn on the pump, then equalizes at a running level...When I turn off the pump the tank water level drops to the level of the overflow...

What keeps the water from draining the 1.5" to the top of the standpipes, when the pump is off??

When the pump stops, the level drops 1.5 inches to the stand pipes and stops, just like I want, then when I turn on the pump it goes back up 1 inch. This 1.5 inch drop fills the sump up about halfway.

Since my pump is not working, I will experiment with this more when I get the pump repaired or replaced.
