Overflow Question

Also if you go with a CS 102 that is rated for 1200 gph and a pump that is only rated for 900 gph you will need a gate valve to slow down the flow form the box to the sump in order for the pump to keep up.

Hope that makes sense.

yeah that makes sense, thanks, the more i thought about it thats what i figured you meant.


@axe_man16 - Ive read numerous threads on various forums debating these two overflows which actually confused me even more. Ive read that even u tube setups can eventually have an air bubble buildup causing them to fail? Even if the airpump on the cpr failed wouldnt you have time to notice a slight air build up between the siphon?
