P-trap with union vs glued-up in crawlspace for shower

[Rocknroj]

Greetings.

I am replacing an old p-trap for a shower.. Access is in a crawl space, about 20 feet from the opening. Should I use a fully glued trap or one with a union.

Any code requirements that dictate which to choose?

Pros and cons?

Thanks in advance

We always use a solvent weld "glued" p-trap on tubs and showers.
I do use tubular traps with unions on kitchens and lavs.

I think a plumber will get things right the first time, which is needed with glue. A novice might tend toward the slip connections because it is more forgiving to the less skilled. I am one of the less-skilled.

Would a trap with a union for a lav be good enough as a cleanout?
