So, I got the materials to build a DIY spray bar for my Eheim 2236 filter. I just had a question about PVC glue?
Is it safe to use?
Is there a certain kind I should look for?
I have a clear and a blue type out on my work truck.
I have a salt water tank and have used the purple primer and the clear glue and have not had a problem, but I do let it cure for a day or so before I run water thru it just to make sure that there is no glue getting into the water. I know the stuff dries fairly quick, but......

I use it at work all the time (HVAC), but that's for drains, I know some drinking water runs through pvc, but I wasn't sure if if was a certain type. Well, I'll work on doing a dry fit and wait to see if there is anymore feedback.

pvc glue is safe as long as it is cured.

PVC glue is safe when cured but when I used to build spray bars for tanks I never used it. With straight cuts the fittings tap on tight enough to hold and then if you ever need, it comes apart easily.

So, I got 1/2" CPVC, 3 elbows, (1) 1/2" female threaded end, end cap, and a Barbed male treaded adapter. I cut all the pieces to fit. After dry fitting it, I realized the bar should be 14" instead of 12". Now, I only need to drill, glue and paint it. So, I was wondering how many holes to drill and about what size should the holes be? I was thinking 7 holes 1/8" big spaced about 2' apart. Any suggestions would be appreciated.

Nice. I'd use 1/4" holes.

You know what. I would even consider 3/8" because of the risk of getting debris stuck in there.

I make mine with 1/8" holes about an inch apart.

Okay, I've glued the bar together, except the spray bar that goes into the last elbow. This way I can change the hole size and bar if need be and clean the bar out. I let it cure for 2 days PVC and Paint. (Fusion paint) I Drilled the holes 1" apart. The holes are between 1/8" and 1/4", 3/16". I added two very small holes to the top that shoot up more. They give a little ripple to the water on the top of the tank. So, far I like the water movement. I might go ahead since I have left over straight pipe and drill out a bar with 1/8' holes and see how that moves the water. I included pics.

I made my holes 9/64ths, 1" apart. They water does not spray as such but it comes out in a steady stream agitating the top of the water.
