I will be installing a sump pump in an old farm house that has a drain in the basement that dumps into an old drainage field tile. The house has two seperate basements sperated by a crawl space. The newer basement built during an addition 30 years ago already has a sump pump that using a plastic water line going into the tile drain in the old basement and works good. The old basement needs a sump as well and I would like to place a valve in the dischage line so I can alter the flow of water if I choose.
The problem is the tile line works well and is legal to use for the sump pumps but in cases of very heavy rains the ground will become so saturated that the tile line can not keep up causing the old basement to flood. I would like to have the new sump pump in the old basement also dump into the tile but also have a valve in the PVC discharge line so I can divert the water during times of very heavy rains so the water will then exit the basement wall above ground and connect to a flexible hose that will make the water run away from the house down a slight slope to help keep the tile from backing up during those rare 5 or 6 inch rains we get every couple of years.
Is there any problems using a valve and alternate routing? Do I need to install a check valve above the pump as I see some web "experts" suggesting? The newer basement's sump pump does not use a check valve and its line goes up a good 6 ft before going horizintally through crawl space and then back down to the tile line in old basement and it seems to work just fine.
