Great product By Sean on 3/15/2014Sean would recommend this product to a friendMade my life easier. Breaks down easy and no leaks. The best part is peace of mind.
Check it out! By David on 12/14/2013David would recommend this product to a friendSometimes we as aquarists spend money only on filters, rock and stock for our tanks........DO NOT cheap out on this item. This check valve is super quiet and works well (tested it out) not to mention you get an extra union in your build. I am super satisfied with this item and will get it again on my next build.
Wouldn't Run a Tank without It By JC on 5/12/2013JC would recommend this product to a friendVery reliable and also simple to clean. It takes away the need of adding an additional union to the plumbing system.

To piggyback on Richard's question. I'm using the braided vinyl for my return with the CPR return. I need to get a check valve in there as well. So with this valve would I be able to use PVC cement to attach it in my vinyl line? Or would I be able to use more ratcheting clamps? Just need to know how I can get a check valve in there safely.
Bulk Reef Supply Hi Andres,
These check valves come ready for rigid pipe. In order to use flexible tubing you would need to first glue in a barb fitting, for example the street x barb fitting. From there you can put your braided tubing over the barb and secure with ratchet clamps.

Do you guys recommend placing these in the return lines routinely? How much will they decrease the flow back into the tank due to increased resistance in the return line? Thanks!
Bulk Reef Supply Hi Sean,
The best thing to do would be to set your system up so there it is not a problem if there is no check valves (so you have enough room in the sump to handle the water). Then if you want to, you can add check valves for convenience if you like (you will have less issues like skimmer overflows if the sump doesn't fill with a bunch of water every-time the power goes out). They will have a bit of an effect on your flow but for the most part its not something you would notice with the naked eye.

Does this check valve attach to pvc pipe or flexible tubing? If pvc are the connections threaded or smooth?
Bulk Reef Supply Hi Richard,
The check valve is a slip connection for pipe (which would be smooth).

My return from sump to display tank is 3/4" clear tubing. Would this product be best to prevent back siphoning?
Bulk Reef Supply Hi Becky,
This product would work just fine for that purpose. Just keep in mind that the fittings on this valve are slip fittings (for PVC pipe) so you will want to glue in a pair of barb adapters like the ones linked below so that you can use it with your flexible tubing.
The golden rule of plumbing is that every job takes three trips to the store. While this can be frustrating locally it can be much much worse when shopping online. Being short a fitting or two can delay a plumbing project for days. Here are some quick tips to avoid this.
- Plan your plumbing on paper
- Don't skimp on unions. Unions allow for easy breakdown and maintenance as well as remove the need for precise elbow placement. Use them as often as possible.
- When in doubt order extra. We happily accept returns for a full refund (less shipping) on all unused fittings within one month of purchase. A few extra bucks in return shipping is less frustrating then a project delay.
