Those that use gate valves

[linkedsilas]

do you buy slip to glue or threaded and why
I’m going to buy some unions for the manifolds and other areas but didn’t know which kind of valves I should purchase

Really depends on:

- do you have equipment to thread pipe or can you buy pipe segments of the appropriate length?
- is there space to rotate the needed pipe or fittings?

It’s somewhat easier to custom fit solvent welded parts.

I used threaded gate valve with this, it worked great:

I thought it might be easier to disassemble and replace or retrieve the gate valve if I ever needed to

Like what above said 99% of people wont have a access to a pipe threader. What this means (just in case you didnt realize) is that you would then need a male to slip adapter. In the end you would have threaded and glued and add quite a bit of length to your valve.

right I didn’t think about that

Threaded fittings all day. I don't mind having to cut a $.69 fitting out if plumbing needs adjusted, but those gate valves are expensive! Make sure you use the proper pipe dope...

I use threaded just so I can reuse them later on if I change my mind

If you do go the threaded route I would just use Teflon tape instead of dope it's a lot easier. Just wrap the threads 8 times clockwise.

Slip with unjons glued on either side for moi

I used threaded gate valves for the fact they can be reused, but I made sure they were connected to a union slip so they don't need to be threaded in place, I just finished my plumbing here's a pic, side note I used the pipe paste as well, its non toxic, and easy to apply.

I did a slip slip gate valve, and put a union on each side of it. Easy to remove if it needs to be cleaned

I prefer threaded, because it's easy to remove them if I need to fix something.

For a slip -> thread adapter, buy a long piece of SCH 80 PVC pipe nipple (the pipes that are threaded at both ends). Then just cut it in half. Boom. 2 male thread -> slip adapters.

I'm using a threaded valve, NPT Male x Socket adapters jointed to flex PVC. That way if I need to change out the valve or plumbing for cleaning/maintenance, I won't wreck the valve.

With the fittings that are available, there's no need to make the thread on PVC pipe.

Teflon tape is not designed for pvc fittings. Its easier, less messy, but much more prone to leaks and over tightened fittings.

Sorry but your wrong! I did irrigation installation on commercial and residential properties for over 8 years. We used teflon tape for almost all threaded fittings and never had anything leak as long as installed properly. Teflon tape is more for plastic pipe dope is more for metal

I've seen plenty of professionals do the same, but I usually go with the manufacturer's recommendations.

Just because you did it for 8 years one way does not mean it was the correct way.

Depends if u can take the valves apart and if u want to use unions.

Slip for peace of mind. Once it’s in there and glued properly it’s not going to leak. I don’t use threaded fittings anywhere on my plumbing.
