You`ll need to get a HOB overflow and put a 20 or 29 gallon tank under your tank in the stand. You`ll also need a pump to return the water back up to the main. Do a search on this site on sumps and you should get some good DIY ideas.

ah... found it... thanks.. im afraid to do DIY because of possibility of a flood

[mike3epanda]

so what happens when they return pump is stronger or weaker than the overflow?... isn't it almost impossible to have it matched of same gph?

If the pump is stronger use a valve on the pump output to reduce the flow back into the tank. If the pump is weaker then there is no problem.

but wouldn't the sump overflow if its stronger?.. also how do u use the valve to make the return pump weaker.. TIA

I ran a pipe from the return line back into the sump in case the pump was stronger was too powerful. This way I can control the flow back into the main without harming the pump.

[mike3epanda]

so how does that work?... wouldnt most of water just go back?.... and it would harm the pump if it ran out of water to quick?... sorry for too much questions

The output from the pump is what causes the water to overflow. The overflow box will stop if the pump stops flowing thus stopping the sump from overflowing.
