HOB Overflow Flooding solutions

Well I guess my problem is solved then, I will just get the bits and drill the back and not worry about the HOB overflow. Thanks again for the help.

 

I recommend that you somehow elevate you return pump in your sump so that if the siphon would be lost then only so much water could be return to the tank before the water level dropped in the sump and then the pump would pump air in the tank. of course this would require you to watch your water level closely in your sump which you should do anyways...of course this probaly wouldnt be good for your pump if siphon was lost but hopefully you would catch it before too long. and your DT's water level would rise but not to where there is an overflow

 

What you said made no sense to me. Please explain.

 

I think his logic is that if the return pump is not on the bottom of the sump, it will pump a little less water into the DT when the HOB overflow stops flowing.

 

keep your inside box as high as possible to that helps.........my water level in the DT is like a 1/2" from the top.
my sump level allows the DT to drain until the return breaks suction and fills it about 1/3 from the top LOL....close but works
I have an EShopps sump love it as the main sump chamber stays at a constent level...good for keeping your skimmer from fluctuating

 

That makes no sense to me either. You are still dealing with the same amount of water that will be returned to the sump. Just keep one of the returns close to the surface so that the suction breaks sooner than later.

When you have the water levels where you want them, turn the return pump off
and make sure that the sump does not overflow. Adjust the amount of water, or raise the return if necessary, then mark the safe zones on your sumps return chamber with a marker or whatever. The maximum and minimum water that you want.

 

I am talking about when the u-tube breaks siphon on my tank then it is unable to overflow to my sump therefore. The level in my sump keeps dropping but the sump keeps pumping water to the DT which could cause it to overflow, not the sump.
Sorry I guess I misunderstood the question:/

 

Yours loses its siphon? Do you have the u-tube on the correct side of the overflow? They are designed to not lose siphon.

 

Exactly. The u-tube should not break siphon whether the pump is on or not.

 

Yeah, I didn't say I agreed with that logic.

If the U tube loses siphon, something is wrong. That's when you get wet carpets.
