Drilling problem

[reefdogg1107]

Ok well everythings running fine and if an emergency happens the sump doesnt over flow. The lfs didnt say anything about the plumbing i did little research but i guess i should have done better.

Its all a learning experience, use this site to your benefit. A little reading will pay off big around here! :bounce3:

It's not the sump that overflows it will be the tank , if your not tuned exactly what do you think happens? There's two scenarios one is your undertuned and there's bubbles and noise below the other is over tuned where the pump out competes the drain this is when the tank itself overflows

your sump is way too full as well…hopefully this is a power out pic and not an operating pic, other wise you are going to have flood troubles with back siphon….

if your fish store told you to put that valve and check in the drain line i would seriously be looking for abetter store, as they know very little of what they are talking about..
you should remove the plumbing from the drain, an redo it wit a simple drop as mentioned and add either an air line or open top…

you really should either buy or build an overflow box to control and skim the water properly…

you should also redrill the hole for the return to also accommodate a 1" bulkhead, then either bush it down to 3/4" or use a valve to control the flow better. or somehow figure out how to make it an emergency drain, and then just run the return up the back side of the tank and over the top.

Its a union not a check valve. And the power was off bud

I would build a simple overflow inside tank. That would fix the sump of flooding potential. As far as tank overflow, the baffles look pretty high so I don't see but a few gallons before the pump would be suckling the last sump chamber dry. Guess it depends on how high you keep the water lvl in tank as to if it would overfill. Jmho

There is also the added benefit of surface skimming of the overflow box in tank. Wouldn't have to be that big.
