Acrylic pipe is probably the cheapest and easiest to get. Amazon has it: https://www.amazon.com/11-7-Polycarb...lic+pipe+clear To make a "tee" out of it requires some skill. And, shipping charges for things like this are pretty high. This is how I would make such a device though.

I can use a regular PVC Tee and extent the vertical with the clear tube.

I have had trouble finding acrylic pipe that has the same diameter as PVC pipe. I finally gave up trying.

I found some acrylic at USplastics. It's a little cheaper than PVC.
For prototyping, I might use a tube from a python water changer I don't use.

Oh! I found some clear 2" pvc tubing off eBay for $10 with free shipping. The walls are thin but it should work.

If I remember correctly, the cement that works well with acrylic, also works well enough with PVC. But, the 2" PVC tubing is the easiest way to go. This should be interesting!!

I've used these check valves from clippard, http://www.clippard.com/part/MCV-1BB
previously in my CO2 setup but they both failed. I guess when in contact with water (dirty aquarium water), it fails. I have a spare one but would a cheap check valve from the fish store be better?

I have been using these check valves, https://www.usplastic.com/catalog/it...3369&catid=489 in my CO2 system for about 3 years, with no failures yet. I have had, one in my tank, in the water, with CO2 going through it for all of that time, and it still works fine. They are made of plastics that are highly chemical resistant. Shipping costs for buying them drive up the cost substantially, but I still like them. I mistakenly bought the 3/16 inch size the last time, so it can be difficult to slip tubing over them, but they still work. The 1/8 inch size works much better.
