Valves???

[stevearthur]

Well I am looking for suggestions on a valve that would be between my return line and my water pump. Any suggestions? Gate? Ball?

Ball valves will work just fine on a return pump.
Ball valve= cheap, hard to make fine adjustments.
Gate valve= about 3x the cost but makes small adjustments a breeze.

Is it cheaper to buy flexible tubing online or locally?

HI,

I have order from here 5 times with no problems.

I also think its easier to order online, then try to find all the sizes from a spa company.

You have to order in 5 foot increments

They don't sell hose barbs do they? I didn't see any. I 'll need two more hose barbs, two 90 hose barbs, a valve, and some hose.

My local Home Depot sell the hose and the fittings.
I would think it would be cheaper than buying online and paying shipping.

Flex tubing yes go to Home Depot.

If you want Flex PVC go to the link on my last post.

What is the difference in flex pvc verses v. hose? Should I use a union ball valve or not? My design is a submersible pump to the ball and then to a scwd. Is it better to use a gate valve on the outlet from the main into my fuge?

See THIS (http://archive.reefcentral.com/forums/showthread.php?threadid=168265) thread.

If you want to be able to precisely control the flow, go with a gate valve. Ball valves are not good at controlling the flow. They are better for on/off applications.

I find my ball valves on my refugium lines, retrn line, and tank to sump line, almost impossible to dial in well. I should have used gate valves for sure. That is why my next DIY uses only them:cool:
