Check valves on return

[CaptainB]

I'm going to plumb check valves into my return, not because I need them to prevent a flood but just to keep the level constant when I shut off the return to feed and less disturbance when I turn them back on.

Are the wye ones from brs better than the flapper/swing ones? Both seem like you can tear them out pretty easily if need be.

I used check valves when I first started many moons ago. If you don’t clean and maintenance them. They are useless. Just flow restrictions

We also didn't have 3000gph DC pumps with feed modes many moons ago. I never used them either because I know they fail. But as a nice to have they make sense to me now.

Easy enough to drill an anti siphon hole.

A check valve will probably be more of a headache than a siphon break, or even hooking a DC pump to a controller for fine tuning a “feed mode” (such as VDM module on Apex).

Quality gate valve

I picked up some small mesh bags from Neptune's that have a Velcro closure. When I turn off the flow to feed, I secure them around the outlet nozzles on the return. When I turn the flow back on...it catches any detritus from the sump and disperses the flow...then remove them after about 15 minutes
