Plumbing not pushing all the way into union? Is this okay?

[Leon Gorani]

I am plumbing my tank with pipes and unions bought from bulk reef supply and when I put a union onto the pipe it looks like the pipe doesn’t push in all the way. There is some space on the inside, Is this normal? If I use a lot of force then maybe I can get it pushed farther in but my question is, is it normal that this is how far the pipe will sit inside the union? I’m guessing that after it is primed and glued that it will not matter? Since it will practically be one piece after it’s glued right?
I am plumbing my first tank and I just want to be sure. Thanks y’all. Here’s some pics of how deep one pipe goes into one of my unions.

in my experience, after glue is applied you will easily be able to push it all the way to the end

Hi I found a similar issue when I was doing my build and this is normal when you are dry fitting. Do not push the pipe in further on a dry fit as it will be difficult to separate the fittings potentially. The pipe WILL go in all the way once you add primer/glue. In fact, you either need to add a little extra length to account for this or just stick with the tick marks you have in your photos above.

Yep, it should be fine once you have the glue. It will lubricate things a little bit (prior to it drying of course).

Even if it does not bottom out, 3/4” solvent welding shoulder is more than enough.

Like other said,when dry fitting you won't get full make up made. Once its primed and glue and inserted into the fitting it'll make up all the way. Give a 1/4 turn and hold it for about 5-10 seconds and you are golden.

Yes don't forget to do the holding part mentioned above until the two pieces fuse together, otherwise it will back off some.

I work with SO MANY people who do not practice this. Also,a lot of people do not bevel their pipe either. I bevel regardless of size,but most people will tell you only 1½" and bigger need it.

My QC guy at work,wants every size done,which I feel is a good practice.

Also,if you want clean joints,if you bevel your pipe ends,you can get away with only priming and gluing half of the amount of pipe you need to.

Well if I did not have the parts to repair it I would maybe use silicone and put it back together so you could run and replace it later
