Whats the best pressure to run this drip line for short runs of approx. 20 feet off mainline?

I run 100 ft segments off a 1/2 inch line. Its gravity fed at about 10 psi, and works very well. I don't have exact figures, but my emitters at that pressure put out roughly .5 gph

If by best you mean most entertaining, try 200 psi. If that doesn't work, crank it up some more. Sorry, I suffer from extreme sacrasm. Your question is too vague.

Generally drip systems are designed to work well at 25 psig and if you give them a lot more than that, they can fail.

I run about 100 total feet of this line in two planters (about 6 foot lengths run off of a 1/2" poly line). I use a 25 psi pressure regulator. It really all depends on the pressure in your water lines whether or not you really need to use a pressure regulator, but in general it is a good idea for drip so that the connections don't leak and the lines don't pop off. Also higher pressure means more water flow out of the drip line, which may or may not be a good thing.

System needs between 20-30 psi to be effective. Most "normal" houses have a water pressure of 40psi or better, which is why this system comes with a regulator. A low pressure well should operate at or slightly above 30 psi, so it should work perfectly fine.

I use it on a low pressure (30psi) system and 1/4 inch lines. Works okay and keeps my orchids blooming and healthier.

No. I rigged something up to do exactly what you're asking and found that I didn't get even close to enough pressure/flow to my mini sprinkler or drippers. You really need the half inch and then use the barb coupling to come off that line to the 1/4. This will save you a lot of trouble.

Going from a 1/2 line to a 1/4 line requires adapters and lines coming off the 1/2 line. Since we have about 60 drippers on our system we plug the drippers directly into the 1/2 line.There is a punch you can buy for punching the holes. We have had success using a nail in a pinch. The red drippers are much cheaper than others we use but they leak around the basewhere the Rainbird drippers do not. They don't work well plugged directly into the 1/2" lines.

Mine was set to cut in at 40psi at factory and I installed a pressure valve in the pump outlet line and set it for 60psi but it can go a little higher if you think your water lines can hold the pressure.

I really can't answer but I have mine installed as a recirculating line and whatever the house pressure is how many G.P.M. you get.

U just have to use low flow and keep on heat. The lower the flow the hotter u get. U should not have to go so slow for 80deg. I get up to 125-130

Unless that line is maxed out (total gpm of valve less the gpm of all the drips already on the line) it should be fine. But may also depend on how long you run the water. all drip irrigation systems parts put out so much water per hour. It would also depend on the type of soil, and how densely it is planted.

It obviously depends on the distance you're running the pipe; for this unit, 1/2 inch black pipe will work well at up to 15 feet

I do not believe that this can generate ample pressure to use a diffuser. Instead I'd think the hose would pop off the reactor chamber. Although, I suppose you could put some sort of clamp on it. This setup works pretty well for a smaller planted tank. I ran it in a high light 29g and the plants grew faster than I could keep up with.

The flow rate is lower than a standard hose. However, the pressure should be adequate for your purpose.

20 gauge is fine for short connections but I would use 16 or 18 for long runs. I used lamp cord (18 gauge) for about a ten foot run and it worked OK. If you use smaller wire for a long distance it will work but your light output will be diminished. For those who don't know - the smaller the wire the larger the gauge, so a 20 gauge wire is smaller than an 18 gauge wire. Think of electricity flowing through a wire like water flowing through a pipe - the bigger the pipe, the easier it is for water to flow through it.

I tried it with 1/4 inch and there is not enough pressure to go more than a few feet. I wanted to do my raised garden. Spent a lot of time piecing it together and the connectors broke as I was setting it up, then it did not work after the first 3-4 feet. I took it apart, plugged the sprinklers into 1/2 inch and was good go to.

The system you use is irrelevant, a drip line is a drip line. The only thing that matters is that your system uses 1/4" line. No connector needed this plug snugly into the end of a 1/4" line.

I have one zone with a small drip setup for my potted plants. It only runs for about 4 min. Once a week. So far no problems.

If you are needing to make the turn in less than a 2 foot radius, I would put in an elbow. I've had to dig up several and do just that on my 5000' of drip line.
