Plumbing Question - Non-kink tubing

Ask kevin95695 and wpnorton and they will tell you, "with kenny it's all about asthetics!" Your absolutely right and when I'm done I always hear, "that looks nice". For me it's not just a trip to the hardware store to make do with whatever they have.

So here's the scenario. The tank build is coming close to an end. While running the set up in the garage I used clear vinyl tubing for the lead and return for the sump. As you know, with time that gets to be funky looking. So I would like some black hose and preferibly "non-kink" hose.

Anyone know if this will this work?

John at woodland aquarium has black vinyl tubing. Sells it for the same price as the clear stuff and it looks much nicer.
 
Thanks Tilmo! Is it the non-kink stuff (ribbed) or just regular tubing.

Funman, here's a picture. I posted the link above also which has a "little" more info.

I would not use that stuff. It looks like it would crack at the seams to me. How thick is it? Is it saltwater safe? Rated for pressure?

Flex PVC is made in black and is much more aesthetically pleasing IMhO.

Company emailed back and stated it can handle 15PSI. Anyone know the typical PSI of a 1000gph retrun pump?

Also the ripples are only on the inside for the 1/2" tubing. All other sizes the ribbing is external.

Definitely not suitable for plumbing a reef tank. Discharge hose is meant for low back pressure (like pumping water from a pool to a floor drain) applications.

For comparison's sake Schedule 40 PVC has a working PSI rating of ~450, Flex PVC is 100 PSI.

From the flexpvc.com website:
#Application guidelines: Flexible PVC Pipe should not be used in conditions of deadhead pressure. There should always be a flow through the pipe. Constant deadhead pressure may balloon the pipe and eventually it may fail. Please keep this information in mind when selecting flexible PVC pipe for a project.

Matt,

If I understand right, you are saying the non-kink hose I posted is not suitable. Is the flexible PVC not suitable either?
 
KMP...You saw that I used the 1" and 3/4" white spa-flex for my plumbing. It's flexible but not as much as you might want. I think the problem is that the softer you get, the less PSI rating you get.

I'd figure a way to use that Black spaflex (PVC) with your system. If you have any hairpin turns ...you just use a 45 or 90 fitting and glue it.
 
Well I've shy'd away from the non-kink. See - asthetics aren't everything - I'd hate to have a flooded living room. In a sepearate thread I was told our systems only run (no more than) 20 PSI.

Anyone know where you can get black spaflex locally (I commute daily so local for me is Fairfield - Woodland - Davis - Sac)

Sorry, the non-kink hose=NOT suitable.

Spaflex/Flex PVC IS suitable for plumbing a reef tank, but you cannot put it in a "deadhead" or "dead end" situation where the pump is on but the output is completely shut off by a valve. I think this only becomes an issue with very large pumps and large diameter FlexPVC. I would honestly not be concerned about it.
 
you can get spa flex at home depot. I used it in every spot i needed pvc overflow, return and closed loop. I like it, i may not be as sturdy as hard pvc but its done great so far.
 
It's a gravity fed return from an upstream refugium. The flex hose is a fairly snug fit over the pcv which goes about 12" down into the flex. I did also buy some smaller ID hose that I planed to run from the pump to the fuge, but the id of the hose does not fit snugly enough over the hose barb. It is made of a rigid plastic spiral that is enveloped by a softer/flexible heavy duty vynal looking product which is smooth on the inside. Nice stuff...but I'm not sure how to secure it well enough to trust it under pressure.

A hose clamp might help, but over rigid PVC is not what it's designed for. Even clamping it down there's nothing to grip on to. I talked with several engineers who are very experienced in moving water and none of them have seen this stuff before. It looks good, but honestly I would ditch it and buy a product that has a long track record of working correctly. A few bucks in cost is not worth risking your tank/floor to a flood.
