Moving, setting up a 240 and just cracked the sump....

Any ideas on good sumps. I'm in a hurry and will probably end up buying a new one.

Tough way to start a new year. Just do a DIY sump if $ is an issue. You can find many of them at the DIY section.

Post up some picks of your old sump. Since it is a sump, it will be easy to fix because it doesn't have to be pretty. I dropped my 55G acrylic. I spend about $10 to buy the Weld-on and got a couple acrylic scraps from the plastic shop. It was easy.

Basically, I'm thinking that your pump can only flow as much as your drains allow, and as long as your sump is large enough to hold the capacity of the extra water, there is no way that it can overflow.

Tell that to your pump!!!

Doesn't really work that way. Your pump is gonna flow what it's made to flow. This won't vary based on what your overflows are draining. The only thing that will reduce the pump's output is head pressure, or restricting the outlet a bit.

If your pump can push 3000gph, it's gonna try and push 3000gph regardless. If for example your overflows are capable of only draining 2000gph, then you're gonna have a problem. The overflows will back up, the tank will flood, and your pump will run dry, sucking air. This is because your pump is pushing out more water than it's receiving from the overflows.

Sumps can handle A LOT of flow, much more than stated by the manufacture. The bottle neck in the setup is the overflows. If your overflows are too small to handle the pump's flow, then you will have issues.

Thanks, I should've worded my statement a little better. What I meant to say was in order for your system to work correctly, you can only have a pump flowing as much water as your overflows allow or less. Of course, the pump will put out as much water as it's designed for. Lack of better wording on my part!

Ah yes, that's exactly right. This is why many people oversize their overflows

I'm not sure exactly what size the overflows are, but I do know that I saw the setup and how it worked. It's perfect and very quiet and the original owner showed me that when the power to the pump was off, all the water drained into the sump with out overflowing. I just can't wait to get it up. We're moving Feb and my goal is to fix/buy a sump, rough up the stand and canopy for prime and paint in satin black and move it all in, brace the floor, tear down a 150 all in 3 weeks or so!
