- Return Jet - CPR Aquatics
The CPR Return jet offers a fast and convenient solution for plumbing return lines up and over the rim of the aquarium. This is a great option when drilling the glass for a bulkhead is not practical or possible. The U-shape of the return jet allows the assembly to simply hang right on the rim with no special plumbing required. Just pick the Return Jet sized for the flexible hose you are using from your return pump, and attached to the molded barb, and you're set! The return side will sit below the water surface to avoid excess turbulence and splashing, and a custom ball and socket connection on the return nozzle allows you to adjust the direction of flow to wherever you would like in your aquarium.
We do recommend the use of some plastic ratchet clamps or other clamping solution to ensure a secure fit on the barbs. Return Jets are available in two sizes for either 1/2" to 3/4" ID hose, or 3/4" to 1" ID flexible hose.
Note: Hose not included. CPR Return Jets use a custom ball and socket connection to allow the flow to be angled anywhere in the tank. This socket is not designed to work with other ball and socket style connectors.
Gets the job done! By imjesstwoone on 9/12/2019imjesstwoone would recommend this product to a friendI have used these return jets in both sizes for 5 years+ & (fingers crossed) never had an issue with the tubing coming off - WITHOUT a hose clamp. Just for redundancy, I've added hose clamps on my latest installs. However, every size is TIGHT & secure fit with exception of the 1/2". Fat chance you'll get the 1/2" tubing onto the jet within 10 mins, let's even say 20. You will think the 1/2" doesn't fit or you have the wrong size tubing.
Regardless, with a hole drilled in these things - they have never failed me. Read through the reviews on BRS & follow the tips included. Esp the foam piece across horizontal section.
Some cons - these are way bulkier than you would expect. The space between the front & back vertical sections are too wide. Secure the tubing to your tank some how or these will flop all over the place. Finally, these go deeper in the tank than you might like. Most people only use return flow for surface agitation. Depending on your water line, jet end will be 2-3" under water.
For those who do not mind this over the back tubing vs drilled returns, this is a go to.
Not for 1/2" Vinyl Tubing By Chris on 1/26/2019Chris wouldn't recommend this product to a friendIt seams fine for the price, but as other reviewers have mentioned putting 1/2" tubing on this may be a problem. The end of it measures 5/8". I tried to put 1/2" vinyl tubing on and there was no way it was going on. The OD of the tubing is 5/8". Maybe something softer like silicone tubing would not be a problem. I was only going to use it for water changes, hang it over the edge connected to a pump in the fresh saltwater bucket. I bought a Two Little Fishes 1/2" ball valve as well for the setup and that worked just fine with the same 1/2" vinyl tubing.
My not recommended is for use on 1/2".
Can These Guys Even Measure? By Dave on 8/7/2018Dave wouldn't recommend this product to a friendThese returns absolutely *suck*. The smaller version is supposed to accept 1/2" and 3/4" tubing. I'm here to straight up tell you that the manufacturer *cannot* measure worth a tinker's damn. To get 1/2" tubing onto these, you'll need a) silicone grease, and b) some *really* hot water to soften the tubing. You'll also need an abundance of patience, a clamp, and something to really get your adrenaline pumping to get the strength to wheedle that 1/2" tubing onto the fitting, let along inserting it to a reasonable depth in order to get a clamp onto to tubing to hold the tubing tight to the fitting.
You can bet your sweet patootie that the next time I need to use this type of return, I'll be hand-creating it out of PVC, adapters, and LineLoc (which these aren't compatible with). Stay away. Far, far, away. Unless you like inflicting punishment on yourself, in which case, order a dozen of these and you'll be content for quite some time.
Works well By Thomas on 7/2/2018Thomas would recommend this product to a friendIt works well. Not very good for a timeless tank. It is wide and can slip back and the water shoots up. It worked in a pinch, will probably still a hole and add a bulkhead for a return.
Bargain Alternative By Tedzilla (R2R) on 3/23/2018Tedzilla (R2R) would recommend this product to a friendI have 3/4 inch tubing, and went with the 1/2 to 3/4" option. I just cut the 1/2" piece off. and it works great. It's easy to drill a siphon break into. I am going to build an acrylic holder for it, to make it more steady on the tank. It's a great solution if you aren't ready to drop more $ on a return at the moment. The only cons I have are that it is wider than the tank rim (hence the holder I am making- which is fine), and the actual nozzle is super tight fitting.But that's better than being too loose, so I am not complaining about it at all. Which is why I'm going to still give it 5 stars- it does the job I needed it for- bottom line. And it's inexpensive.
Good product. By Monsterob on 10/23/2017Monsterob would recommend this product to a friendLooks great. Ill buy another for sure. It fits 2 different sized hoses. You just push it on a lil farther, it gets wider.
Does not fit By Lola on 7/11/2016Lola wouldn't recommend this product to a friendI bought the one for 1/2" or 3/4", it does not fit the 1/2" tubing I bought from BRS. It works fine with 3/4", but that's not what I bought it for.
Great build quality! By Joshua on 3/3/2016Joshua would recommend this product to a friendVery nice product, solid construction!
Does the job By dmolavi on 2/2/2016dmolavi would recommend this product to a friendDoes what you'd expect...gets the water back into your tank. A few modifications are needed to make full use of it though: 1. Drill one or two small (1/16") holes in the jet just below the water line to prevent siphoning if your return pump turns off, and 2. If you wrap the horizontal part in a small piece of foam pipe insulation, it will completely deaden any vibration. Great product.
Appears well made but does not fit appropriate size tubing By Butchy21 on 2/1/2016Butchy21 wouldn't recommend this product to a friendI purchased this to use as a return for my media reactor that I recently set up. I bought the 1/2inch to 3/4 inch size item to use with 1/2 inch tubing from my BRS media reactor and it does not fit at all, making it useless. The item appears to be made well but does not work as labeled.
Multiple uses! By MikeB on 10/8/2015MikeB would recommend this product to a friendThese are great for a simple return. Works great. Looks great. Simple to install (use a hose clamp, obviously, as with any hose on a barb). Zero complications. Done and done.
Additionally, I use one of these when I pump new saltwater into my tanks. I have an old return pump and hose I use to do this, but I have this return jet on the end. So, Brute can full of new saltwater, pump with hose and return jet attached, return jet easily hooks on rim of tank (I adjust nozzle so water shoots directly along the glass to avoid damage to corals or substrate), turn on pump (I use a power strip for an on/off switch) and then, instead of standing there holding the hose for several minutes, I can actually sit down and finish my b.... soda. Keep watch to avoid overfilling, and pull the jet out above the water before you turn it off (to avoid a reverse siphon), and roll the setup over to the next tank, rinse and repeat. This little device made water change day a lot more enjoyable.
Does the job By dave_pr on 9/27/2015dave_pr would recommend this product to a friendIf you're using a 1/2 tube put a clamp around it because it will leak. Another disadvantage is that the u tubes are too far away and will not stay in a single place once you put it in the tank. Besides that, works good.
Are these compatible with 1/2" loc line?
While similar in concept they are not interchangeable. Loc-line is a brand name with its own standard that isn't interchangeable with other similar looking fittings.
Can this be fitted with a random flow generator?
Will these work 5/8" hose?
This return jet in the 1/2" to 3/4" size will work with your 5/8" tubing. We recommend a zip tie or hose clamp to hold the tubing. Feel free to let us know if you have any further questions!
I curious about the dimensions of the 3/4" to 1" return jet. What is length of the drop to the ball joint on the outlet side and how big is the gap between the pipes? I want to use this for a return from my sump and want to make sure it'll fit where I plan to use it.
The gap in the "U" of the return jet is just shy of 2 1/4", so anything under this should be fine. The ball joint starts at about 2.5", and the actual outlet starts at about 3.5" from the inside bend. Hope this helps!
Hi, I've got a tough question for you. You guys are good but if you know this one, I'll be really impressed. What's the maximum flow rate that can pass through one of these (large) returns? I've got a 1,000 gph pump but I think its being restricted. I'm going to get a 2nd one and split the return, but I'm curious what the max is..
This can be a bit of a complex question because this depends upon a number of factors including input pressue and acceptable pressure loss and velocity. Ultimately for most practical applications and regular hobby pump pressures, the most you are going to get through a 1/2" ID pipe such as the return jet would be about 400-500gph. For a 3/4" line you may get that up to a bit under 700gph. Bottom line, for those returns you are almost definitely being flow limited by the ID and losing flow capacity from your pump.
Hope this helps!
Will 1⁄2" Mur-lok Polyethylene RO Tubing fit on this return?
Unfortunately this would not connect directly to the return jet. You would need additional plumbing fittings in order to do that.
