Flex PVC
I am looking at making a closed loop system for my tank, since i am tired of seeing the Powerheads in the tank. However, I know that due to my plans there will likely be one, two, maybe even 3 90 degree turns and I dont want to stress my heads out too much. With that in mind, has anyone used Flex PVC and to what results?
Is it just Flexible PVC (i.e. Carlon Flextube) or is it the corrugated ENT tubing? Also is there any fears to deterioration with the salt water? Also can you use PVC glue with it, or do you have to do some other mumbo jumbo to make the connections watertight. |

I just got parts including flex PVC through the savko.com site. The true union ball valves are way cheaper than any place we looked in town. I also got the pvc gate valves for better flow control. Set up a user account with them before you start putting things in the shopping basket.
The tubing is great. You can see it at Home Depot (spa flex) to get an idea what it looks like but it is way cheaper through savko (1.09 per foot for 1.5 inch) even after shipping. From what I read, the flex pipe results in less noise.

is there any chance that this stuff would work as well...I can get it for fairly cheap, but am somewhat hesitant about putting it in my tank.

I used "Spa-Flex" from Home Depot, and long radius 90's from a local comercial plumbing supplier. The Carlon stuff is the same, except it's gray. I used the Christy's brand blue glue from H.D. as well.

FWIW, normal PVC glue wil work, for a shorter duration then the stuff made for flexible PVC glue. The proper glue is less stif then then normal PVC, allowing the joint to expand/contract. The normal stuff is more rigid, and over time, seperates from the flexible PVC and at some point....POP...lotsa water to deal with

I don't know, i've heard the same with the flexpvc glue (people have had problems.)
I just used Christies Red Hot Blue Glue and regular purple primer, but I put an enormous excess of everything. It seems to have some flexibility. I have heard of people being successful and unsuccessful both ways with the flex pvc. Be careful with SAVKO, I got a letter from them about their website having been unsecure and some stuff got leaked. This following some fraudulent activity on my credit card. I will no longer be shopping there. -A

As I built my tank I used the clear vinyl and barbed fittings with the intention of a more permanent setup eventually, possibly hardlined, when all the mechanicals where added and in there final orientation. I would rather use flex, but hadn't seen this stuff where is it located in HD? Is the Spa flex the same O.D. as typical sch 40? I assume that because you used the long radius 90s reefgeek, that it is. Just curious about the fit of the joints and if the Spa flex is made for those fittings or if there are "Spa-flex" fittings to go with the pipe. Glad you guys are talking about this!!!

I had never heard of flex PVC joints failing like this. 8O Off to check a few crucial plumbing jobs next visits I make.

Anyone besides me using conduit (gray) PVC?
It is designed for outdoor use and has large radius turns so molex can be threaded through it. It isn't rated to carry human consumable liquids like sched 40/80 so there could be leaching problems.
