The drain line is so small that when it gets air bubbles in it then it stops draining. I have water filling into the tank at 4-6 gph so I ended up having my sump flood several times due to the drain line not working.I am failing to comprehend what is going on here. Pictures?
I need the drain hole to be larger or a pump to pump the water out.
I found this pump last night that has an auto shutoff and it turns itself back on once it senses water. It may be an alternative to boldtogether's suggestion. http://www.amazon.com/gp/product/B008EFGQLA?ref_=pe_623860_70668520
