Need some plumbing help. When my pump powers off, I am getting backflow that is defeating my check valve. The water will continue to siphon until the water in the tank drains far enough to break the siphon of the water return, all the while slamming (loudly) the flapper in the check valve. To this point I have been able to manage the backflow with the extra capacity in the sump and by keeping the water returns aimed high toward the front glass (instead of pointing down) so the the siphon is broken quicker. My fear is that the returns may slip so they are pointed downward, increasing the amount of water that must drain before the siphon in the main tank is broken.
I'm not sure if the problem is something I will have to live with, or if I need to replace the check valve. The check valve is less than a year old and I would have thought it would have lasted longer. Any other "tricks of the trade" that I can apply to sleep well while out of town knowing that it would be pretty tough to overflow the sump?
