Dig Drip Irrigation

I am a newbie and I try to add a drip system on a sprinkler system that waters my lawn. This system includes a vacuum siphon valve and the plan is to use it. I go to The Home Depot and got a Y-filter, pressure regulators, 3 / 4 "connector 1 / 2 swivel and 1 / 2 inch tube.
Now the anti-siphon valve is only a few centimeters above the ground. And if I connect the three components above all, it is about 9-10 cm long, I'm supposed to dig a foot or more in anti-siphon first to get this connected?
(I've already done that, but something tells me that I could be wrong.)

Do I need to apply PVC cement type of things when screwing various components? (They seem to leak or no matter how I touch. Esp the relationship between Y-filter and pressure regulator and the joint between the pressure regulator on the swivel connector)

Thank you very much!

I would put it underground by siphoning valve so that nothing damages being above ground.
siphon valves must be themselves if above ground.
for all your nipples using paste or Teflon tape to seal it.
Ive found that the Teflon paste works best good.

and all fittings slip regular use PVC glue.
You can use the purple primer first, but it is not necessary.

I really drip irrigation that much,
but we did not siphon valves use around my workplace. I rarely see them
but they are most often set above the ground.
our business or drip, as pressure reducer is installed below ground ussually in valve boxes.

good luck and hope this helps.

Anti-siphon valve (ASV) must be approx 12 "above your highest drip, Microspray, nozzle or sprinkler to operate properly. If your Microspray emitters or nozzles are above the ASV, then a reverse pressure differential could cause water to flow back into your house through your drip line. This happens especially when for some reason the water in your house is closed and the falls pressure. But even if this occurs, you may have no health threat to a large potential for contamination of water with fertilizer in it seeps back into your system and drip back in the water in your home. However, you must be aware of that.

Do not glue the threaded! I use teflon tape and generally make several envelopes. Make sure you do not cross thread components, or you'll probably have to replace them.

And ... If this has been one of my installations is what I would do:

1. Ugly as they are, I move the ASV to ten more inches so I can rest better at night.
2. I ran 3 / 4 "PVC valve ASV down to a bend in the ground.
3. I can run short or long, the length of 3 / 4 "PVC to a place where I want and could not reach a 10" round valve box containing the filter and regulator.
3. PVC to fit on the filter / regulator and 1 / 2 "plastic tube, as you know, coming off the exit, and the whole enchilada would be covered by the valve box.

Mounting components carefully in a box with valves in the soil does not make things work better, but it does make things cleaner.
