How do you increase the water flow coming into the overflow? I have 2 bulkheads with 1inch tubing going to the sump with a rio2100 pump. For some reason the pump is pushing the water out faster then it is coming in so every now and then I can hear the pump "slurping"
overflow ??

This, or just put a ball valve and restrict the flow of the pump. It sounds like your pump is a bit too much for your overflows.
or ....you will get the max flow by having no air intake anywhere in the line. for example, hang on back type will suck in some air as water drop down. air will take some room instead of water only. kinda hard to explain it without picture...

This is the easier way, but doesn't that increase the load on the pump, possibly causing it to burn out early? You may need to add in the extra friction loss by the valve.

Doing it this way wouldn't add any load to the pump, but then you may need to test to make sure you don't have too much returning to the sump and then overflow it.
IMO, either way could be made to work.
Just to double check, the 2 bulkheads are for 2 return lines to the sump, and another line from the pump back to the tank?

Restricting the flow of the pump will have the same effects as having a higher head height on the plumbing. It should in no way damage the pump as they are designed for the additional height. In most cases, the pump will be a bit more efficient with a little restriction on it. Check out the flow chart for this information.
Sometimes closing the ballvalve on the return just a tad to the display quiets down the pump a bit. It is sorta like adding a little extra head to the tube.
Recirculating excess flow back to the sump is just recirculating water volume not increasing it so you can not overflow your sump doing this if the sump is set up to the correct levels before powering up.
