00:00Top 5 Barbed Non-Return Valves for Aquariums
00:03Okay, so if you're running any kind of aquarium setup anything with a siphon line,
00:08a return pipe, CO2 line, or a dosing system, you know that one small drip can turn into a
00:13flooded cabinet at 2am. So today I'm breaking down the top 5 barbed non-return valves for
00:19aquariums, and honestly, I went through the highest rated, best-selling ones so you don't
00:23have to waste a weekend troubleshooting a leak. These are the ones actually worth your money,
00:28and by the end you'll know exactly which one belongs in your setup.
00:32Starting at number 1, and this is the one I keep coming back to for basic builds.
00:37This is the plastic Pagoda-style inline check valve, and it comes in a range of diameters,
00:423, 4, 6, 8, 10, and 12mm so you can match it to pretty much any standard tubing you have
00:48lying
00:48around. The spring-loaded poppet does the work, so it only lets flow go one direction and stops
00:53it dead when the water backs up. At under a dollar, it's basically a no-brainer.
00:59Nearly 5,000 people have bought it, and for a single cheap insurance policy against a flood,
01:05I'll take it every time. Number 2 is the one for serious aquarists,
01:09the KHCSDV PVDF spring check valve with barbed fittings, and it's a 10-piece pack.
01:15Here's the big deal, it's PVDF, which means it's ozone-resistant,
01:18so if you run an ozone reactor, this thing won't degrade and let go on you.
01:23The barbed sizes, 3.2, 4.7, and 6mm OD, are actual tubing IDs, which is way more useful than
01:30the vague sizing on cheap valves. Yeah, $15 for 10 is more than the others,
01:36but if you run ozone, this is the one that survives. 4.8 stars, and close to 5,000 sold,
01:42so it's clearly working. Number 3 is the fan favorite, and that's a rating of 4.9,
01:48the highest of the whole bunch. It's the plastic one-way check valve in a 2, 5, or 10-pack,
01:54again in those same common diameters from 3 up to 12mm. What I like is the flexibility on pack size,
02:01grab 2 if you just need to replace 1, or grab 10 and stock your whole room.
02:05The Pagoda body is compact and low-profile, so it doesn't stress tubing or sag in a vertical line.
02:12Just over 3 bucks, almost 5,000 sold, and it's the one most people in the comments swear by.
02:18Easy pick for a standard freshwater rig. Now, number 4 is a bit different,
02:24and I think it's the most underrated. This is the 2-in-1 1-2 straight check valve with a
02:29locknut,
02:29the kind of splitter where one inlet feeds two outlets, and each outlet has its own one-way
02:34valve built in. So you can feed two separate lines from a single pump and still keep them
02:39from backflowing into each other. The locknuts tighten down and stay put, which means you don't
02:44have to worry about them loosening off. It's 10 pieces for about a dollar, and while the 4.5
02:50rating is the lowest here, the function it does is unique. Great for dual return tanks.
02:56Alright, that's my 5. All 5 links are in the description,
03:01so you can grab whichever one matches your tubing and your setup.
