Threaded vs slip

[merfish101]

Which seems to be considered better when using gate valves and true unions?

I personally prefer threaded. I use a thread to slip adapter right out of the valve. That way, if you need to make a change, you can take the threaded fitting out and reuse the valve. Just my $.02.

I prefer slip. I have found over the long haul, most leaks come from a threaded connection.

I like slip over threaded to prevent leaking issues (but that may be because i am not threading tightly enough)

Use slip for sure to avoid leaks. But use a small piece of pipe and then go into a PVC compression fitting. It allows you to maintenance and remove the valve as needed.

I personally use a mix of both depending on the situation. For anything that can have a small leak and not be an issue go for threaded as you can take it apart and re-use. For anything that will cause issues if it leaks go for slip and apply a generous amount of glue.

Note: I was able to salvage some of the more expensive fittings such as 2" slip unions by placing them in an oven for 5 minutes and than pry the pipe out :)
