Ball Check Valves????
Hello,
Has anyone ever tried ball check valves in their return lines? I bought a couple but I haven't decided yet if I will use them. Thanks, Ron |

The balls usually move around too much, cause a rattling noise, so I wouldn't recommend using that particular type of check valve. A swing type is better but ultimately unless you have some particular reason for using check valves in the first place I would suggest no check valve at all.

I would also suggest no check valve. They will fail at some point (even with maintenance, and even a brand new one has a potential to allow backflow).
But, since I'm always open to new thoughts and ideas -- I would love to hear your requirement... maybe we can help brainstorm another option, or learn from it

I went with this valve mounted on a horizontal, I never thought I should remove my returns and drill a Anti siphon in them, I added it on mine as I have 30 plus feet of plumbing and this helps even the return line draining at all.

Thanks for the replies guys.
Quite honestly I probably don`t need any check valves but redundancy is always good. My tank is 70 gallons and my sump is 55 gallons. I am going to use 2 90° loc-line elbows to bring my return up and then barely back down into the water so it should break the siphon very quickly in the event of a power failure. I bet I could flow 15 gallons back to my sump without a problem but I guess we`ll see when I get it plumbed and tested. Thanks again guys. |

The best way to install a swing check is vertical, then the head of water above the valve will always drive the flapper closed when the return pump stops. I just went to new Speedwave pump and pulled my check valve apart to clean it and it was spotless inside. Anti syphon hole or a short lock line outlet at the water surface is also a great idea, redundancy is a good thing.
