Deb,
One problem I see is that if the power goes out and the pump return to the tank sucks in air then there will be no water left in the pump end of things to start the suction again.

Have you tried turning the pump off and seeing what happens? Just the first thing I saw, I hope this is not true.

Hey Steve.... :D I'm beginning to like that decorating theme a lot more...

Jon, actually we did the power down thing several times, the tank water level then drains to the sump just till the overflow level, the pipe to the pump never sees air, so seems to work well on restart ?

Just looking at the pic again, and I guess you can't see that the intake to the pump goes to about 1" from the bottom of the sump.

Good, wouldn't want anything horrible to happen to that gorgeous new tank. [img]smile.gif[/img]

Um ... forgive me for I must be missing a piece of the puzzle here. Maybe I'll see this better tonight. My concern is this. It shouldn't matter that the end of the intake pipe is submerged in the sump. If your pump is off, the main display tank will back-siphon down the sump return line until either a check valve slaps shut or the sump return outlet starts to suck in air. So if you don't have a check valve, eventually your return line will drain down to the water level in your sump (which in this case is below your pump). It may take several minutes for this to happen. The main question to address is, is the pump able to suck the water up from the sump level when it is dry? If so, then you don't necessarily have a problem (although I don't know how good this is for your pump). But if not ........

BTW, if the issue is that the sump is not drilled, and you do not want to go the route of a submersible return pump (such as a Mag24 or something), I can offer this: If you want, I have a diamond-tipped hole saw drill bit which can drill a hole into glass perfect size for a 1" bulkhead. I beleive the size is 1-3/4" (not sure offhand without looking at it, it is at home and I am at work ... but what I can tell you is that it is the exact size of hole you want for 1" bulkheads, whatever that is.)

Well, you guys certainly know how to pop the old bubble [img]tongue.gif[/img]

This is why you DIY and we buy.... :rolleyes:

Going shopping now for a checkvalve - thanks eh :D

[Canadian Man]

That's precisely what I was thinking of Tony,

[EmilyB]

After hearing our checkvalve, and experiencing our pain, Tony and Linda have decided to do a repeat mission to the NW to save our asses.

Saturday September 24 roughly 5:00/ish. Of course, reefers of all afflictions are welcome...a demonstration by Tony of tank drilling, to be followed by food and merriment..and maybe a little DOG hair.

[Canadian Man]

I'm in, and katie too :D
