The point is that the outlet is so huge a powerhead would never be able to keep up with it.
Why do it? It has the potential to create a larger water movement than all the other surge devices (at least in gallons/sec moved), as well as much less noise* and bubbles. (*Assuming I can do it with the venturi of a pump.) You can bet I will be calling it the Wandell surge device if this sucker works
Bry, your idea is good in theory, but it could really only be implemented on a very large tank. It's basically a large piston. Imagine if the container was solid, and inside of a stationary sleeve, and you basically have a wave2k type device. The difficulty is in getting moving parts to stay moving in a saltwater tank, and getting it to work flawlessly. Way too complex.
Roberto,
Can you explain exactly how a pressure relief valve works?

well, i did post again back there.. but in my own defense of such a bonehead idea, i think it could work at the expense of a new powerhead quite often.
all that would be required would be the slightest bit of head pressure to vacate the air from the chamber. the water would probably have to be added from the top to prevent the change in head pressure on the pump enabling a correct throttling on the chambers discharge.
water would be exiting this outlet at all times until the water level sank to a point where there was nothing left to pump up from the sump... the problem this is that the pump would be running dry until the water came back down for it to be pumped back up again.
The prototype run...
This is a big stein I drilled a hole in
I just placed the vacuum to the bottom of the glass, no seal involved. It sucked up the entire glass in about 3 seconds.
I'm going to buy some 4" acrylic tubing and PVC fittings and build a larger prototype next week. Hopefully going on my 40 gallon if all goes well.
(Note my helper. I needed a miracle.)

You usually buy them for a specific pressure. I'm sure there is an adjustable out there somewhere. It's probably as available as the frackin' barb fitting I spent all day looking for unsuccessfully.
That is a sweet pump, though. But following it with a 1 horse compressor doesn't sound quiet.
