I'm planning on installing 2 return pumps on my waterbox 220.6 for redundancy purposes. Neptune Cor15's (already purchased). The system was plumbed for 1 return line back to the tank feeding the two return jets in the display tank.
It will be a simple addition of adding a Y tee connector do this however I suspect it would be best practice to add a two "swing check valves" to prevent backflow on each return line from these pumps. In the event of a pump failure this would prevent the water from simply returning to the sump through the failed pump.
Thoughts? Thanks!
