Nice setup but no unions?

Thanks for the input, i have brackets for pipe support just forgot to mention.<a href=showthread.php?s=&postid=11382768#post11382768 target=_blank>Originally posted</a> by Chrsnwk
First off... very neat, well routed plumbing. I'll chime in too about the union thing... they are a really good idea. I'd add a union valve, or a union and a valve on each side of that pump. It's going to need to be serviced from time to time and as is look now, you are going to need a hacksaw to facilitate that.
For an additional $.02 I'll mention one more thing... As we discussed in the concerns on the strength of your stand, water can be rather heavy. When those return lines (and drains to a lesser extent) fill up with water, especially that cool looking manifold you have, it's going to have a good but of heft to it, and it's just hanging off the back of a standard (i.e. not heavy) duty bulkhead fitting, mounted through the relatively thin glass of a 40g tank. You have what's called a cantilevered load that is pulling downward, pushing on the lower part of the bulkhead, and pulling on the upper. I fear over time the bulkhead fitting or worse the glass will crack. Technically, the vertical return pipe from the pump is giving it extra support, but in doing so you are stressing the plastic pump housing, which might lead to something unfortunate there. (which factors into the serviceability/union issue again). What I'm getting at is I'd like to see some bracketry to either clamp the vertical pipes to the fram of the stand, or some other hanger/clamp type thing supporting the horizontal runs somewhere.
Good Luck !

Murphy's 7th law states that all check valves with fail when you need them to work.

Ok, how do you do the siphon breaks?<a href=showthread.php?s=&postid=11731779#post11731779 target=_blank>Originally posted</a> by Chrsnwk
I'm happy to have helped. The stand and plumbing look good. Is that a check valve I see above your return pump? If so, please don't rely on it to avert disaster. Murphy's 7th law states that all check valves with fail when you need them to work. Even if it's a top quality on with sapphire bearings and NASA quality sealing surfaces, all it takes is one little tube worm, adventurous starfish, or baby snail to defeat even the most precise check valves. Please also incorporate some siphon breaks into your returns if you haven't already. Also be sure that if the power fails, the top tank can't back flow into the middle tank, since the path to the sump is impeded by the aforementioned check valve.
