I'm toying with the idea of getting a couple of 50mm motorised ball valves for my two Overflows. So that when there is power they are open but incase of power outage they shut. Has anyone tried this? Currently using them?

I can see a good usage for this. My 1st thought is to use them with a relay and not a controller.I'm toying with the idea of getting a couple of 50mm motorised ball valves for my two Overflows.

Just really to save Overflowing back to the sump. I'd like as little water as possible to flow back in case of power outage.Just curious as to why you would want them to shut? If anything I would be worried they would stick shut and flood on power restoration. If you wanted to do it you just need a motorized ball valve that’s normally closed.
Okay, would you be able to send me a link for one? Haven't heard of a sprinkler valve. Assuming it's used it sprinkler systems? LolIt seems to me that a sprinkler valve would probably be less expensive than a motorized ball valve.
I just saw you're in the UK, but yes. They're used in sprinkler systems and I'm going to guess that maybe sprinkler systems for your lawn aren't as common on your side of the pond as they are over here.Okay, would you be able to send me a link for one?

Check valves won't work for overflows as they are designed to stop the flow from reversing from the normal path. Op wants to prevent flow from the normal path.I would use a simple check valve. Yes, they can fail, but I've never had it happen. You could run a couple of them in series for added peace of mind if you were worried about failure.
Yep. Valves need to be exercised if you want them to be reliable.I'm using a motorized ball valve for my CO2 scrubber. I imagine it would work well in your application as long as you could find the appropriate size.
Concern would be with the moving parts and gunk (snails, slime, etc) messing with the functionality. How often would they be triggered? Everyday during feedings?

That's a fair point! I suppose I could 'exercise' the valve whenever necessary really. I could probably even automate that depending on the valve type. I'm seeing wifi enabled ones. I think it'd be difficult to have 100% failsafe against failure when going the automation route suppose its the risk I'd need to take in to account.I'm using a motorized ball valve for my CO2 scrubber.

As others have stated, best option would be to make sure your sump can fully handle what is "relieved" when power is cut and then add complexity as needed from there.That's a fair point!

Although I would say my pond is in a garage on concrete and water would end up going outside and wouldn't cause property damage so probably a risk I may feel more inclined to accept over another person
Any particular reason why you get your water delivered like that? For that money you could have gotten a high quality high output rodi unit and plenty of saltAn update. After like 5 floods because of a faulty vectra L2 which likes to shut itself off for no apparent reason and loss of 200L of sea water which costs like 80 pound a time to have delivered. I decided to add a secondary sump to handle the excess water. I really should have done it to start with but I was stubborn lol
I do have an Rodi unit for the top off water and did start out mixing my own but it became a bit of a hassle. I also like the idea of using natural sea water, I feel like nature's best. Whether that's true or not I don't know.Any particular reason why you get your water delivered like that? For that money you could have gotten a high quality high output rodi unit and plenty of salt
