Aquarium Air Pump Splitter 10 in 1 Set 3-Way Air Flow Control Lever Valve & 3 Non-Return Check Valves & 6 Suction Cups for Fish Tank Airline Air Tube Hose

Did exactly what I needed. The black rubber nub can go on either side of the metal air intake, so it sits nicely whichever side of the tank your stuff is on. The valves do a good job limiting and/or blocking air however you choose to adjust them. They both would completely shut off the air without leaking if I chose. And I haven't tested the water backflow valves, but they seem to effectively allow air to go one direction but not the other.The connector ends are the right size for a super tight fit around my standard airline tubing. It was actually really hard to shove them on, since the tubing I have is really stiff, but they all worked!

The media could not be loaded. I needed a splitter and I was glad I chose this one because in the fish world if you buy one fish within a day or two you’re gonna be buying more and wait a week or so you will have a tank! Needless to say I went a month and now I have two tanks. Heaven help me if I see something really cool. I might end up with three. I really enjoy this. They’re so easy to operate even if you’re older, you know and have arthritis in your hands which I do have it’s fantastic. Great value for the money. The airflow is awesome. The size is nice and compact and noise level. You can’t even hear you just hear the bubbles.. product rating A+++

Levers make it easier to regulate than the knows would. Easily hook up to three nozzles or have them shut off completely

The control valves work great and are made from good material. The backflow preventers on the other hand were unusable because they all but stopped the airflow.

with a single new air pump for my aquarium, I needed to split between 2 foam filters and 1 air stone. This splitter handles the job perfectly, allowing me to control the air pressure to balance both filters. a great purchase for my needs.

I got this mainly for the splitter. The other parts were just a bonus, so I won't focus on those.The air flow control works great. I split this off so that one tube is running my sponge filter, and the other is running an air stone. I am able to fine tune the air flow to both of them to get optimal pressure from the single air pump.The suction cups that come with it work well, and have not come loose in the few days I have had this, keeping my air lines securely in place.

Based on my experience (and opinion) The check valve part works well on soft hose but not on the the standard hard hose. The only thing that I can think of to ensure a solid fit with the hard hose may be to sand the tip down a bit or try to stretch out the hard hose. Does anyone else have any ideas? The metal gang value was solid. I liked it and it looks as if it may last a long time. So, overall I gave it three stars due to the check valve design (materials issue). I just got the hardware. So, I will revisit my review if conditions change on the gang valve.

Works like it’s supposed to
