How to Connect 3/4" Valve to Manifold 3/4"


How do I connect the 4 port manifold to a 3/4 inch valve (075-DV)?

Can I use a reducing nipple on the inlet side?

Also what is the correct way to connect the outlet side? Can I just use a standard reducing adapter (MiPT x Insert)or do I need to use some combination of the manifold fittings.

BTW. I'm using 3/4" poly pipe.

Thanks

Spears. It has swivels on the 4 ports and a male nipple on the end.

I've never seen a Spears manifold before. Personally I'd never use a pre-made manifold. I'm obsessed with my work not leaking and working on the first attempt. Call me anal. I did find your manifold online however. Just use pvc fittings. Their suggestion to use a female adapter on one end is a bad idea. Especially on a main line. Female adapters have a tendency to crack or leak if not tightened just so. That's reason enough for me to build the manifold myself.
Good luck!

The Spears manifold is really intended for use with male-thread valves.

Jimmy, It's basically a personal preference. I can name a variety of reasons why I don't like pre-made manifolds. I'm not sure you want to hear them all. What I've found to be my some of my best tools being an irrigation tech are, observaton and anticipation. I will name one reason why I don't like that Spears manifold. It doesn't matter that I've never seen one in person. Look at all the unions. Each one has the possibility of leaking someday. Much more than a simple male adapter screwed into the inlet port. I also think Boots is right.
