Mag-drive works too well!

My Mag-drive 5 (500 GPH) pumps out saltwater faster than it can flow back into the sump. I guess I need to get a Mag-drive 4. Anyone in the tri-state area want to swap? I will do it straight up, send me a PM.

Alternatively, is there a good submersible pump where you can adjust the flowrate out there?

 

ALL return pumps should have a gate or ball valve installed inline after the pump. This will allow you to dial down the flow.

 

A-ha! I knew there would be an easier solution...

now let's see if I can find such a valve and some connectors...

...to be continued!

 

You can buy ball valves at any home depot/lowes/ace etc. I do recommend a PVC gate valve though, as they are MUCH more accurate and easy to adjust. However, you would probably need to order one, or check with any local pool/spa supply companies to see if they have any.

 

Ball Valve (FPT x FPT)

Should work.

 

if your using hose tubing, dont forget to pick up appropriate threaded hose barbs, teflon tape, and a threaded ball valve to make everything really easy.

I would look into the gate valve before buying the ball valve. I tried to shut mine down the other day and couldnt get the handle to turn completely closed, I had to pinch the hose shut to stop the water. I learned something from that, if it was an emergency I would have been in trouble. In 2 weeks I am going over to gate valves, I have to take the tank apart anyway when I move. Are there any drawbacks to be expected from using gate valves?

 

Ok, being new to this, I'm not sure what to do...I've found some ball valves here:

Aquarium Plumbing: Threaded Ball Valves

the outlet of the mag-drive is 1/2" and is connected to tubing.

The ball valves seem to be threaded so I'm guessing I need some kind of hose barbs or something? Could someone explain what I'll need to buy to connect one of these valves in-line? Sorry for the noobie question!

Thanks in advance!

 

1/2" x 1/2" hose barbs will work. home depot has all this, I prefer to get this kind of stuff in person. bring a small piece of your hose with you and make sure the barbs fit in the ball valve and your hose before you try them out at home.

Thanks, good idea to bring the hose.
