Good question! I've run a lot of drip/low volume irrigation systems & lines but never one from a high volume system. However I have a place that would greatly benefit if I could run some low volume to my pots.

They do have pressure regulators but I don't even know if that would be necessary. I'm going to have to think about this.

Maybe someone will help us out here.

Laura1 - how did you run your drip/low volume irrigation systems? From a hose bib?

From what I've been reading on the internet, it seems possible to connect a low pressure drip zone to a high pressure system, but you have to dedicate one irrigation valve (an entire zone) to the low pressure system. You can't run low pressure and high pressure at the same time on the same valve. That isn't really where I wanted to go with this, so maybe I'll have to rethink my irrigation needs. Seems like I need to do more research.

I have one zone on my sprinkler system set up as low-pressure drip. The other three zones are all high pressure. All four zones run off water pumped from a well.

I didn't use any kind of pressure regulator but I did run the low-pressure hose through all of my beds for a length of about 150 ft with lots of drippers and sprayers hanging off of it. I've been using it like this for over 5 years with no problems.

It seems like I remember reading that you're not supposed to combine high-pressure and low-pressure on the same zone, so that is probably why I did it that way.

There are standard pressure reduction valves to run drip systems off city water at high pressure. Any store that sells drip irrigation parts will have them in stock.

I set one up for a customer in Ocean Ridge years ago. We just tapped off one of their zones, installed the pressure regulator, and connected the other end to the drip lines. When that zone ran, so did the drip system.

ThatÂs interesting. we are running a mix of high and low pressure on a single circuit and have not noticed any problems. I would be interested to know what kind of problems people think they would see with this configuration.

One suggestion is to find a sprinkler head you don't need (like a popup sprinkler used for shrubs that are mature enough that they no longer need irragation) or you can install a new 1/2" outlet to your existing system. Then all you need to do is attach a drip head conversion kit. It allows you to run up to eight 1/4" microtubes from the single head and you can regulate the flow/pressure to each tube. You can buy the converter at the big box stores. I've used them for years and have had no problems with pressure.
I've included a link to the conversion kit sold on the Drip Store.

I just asked my landscaper how to do this yesterday. He said I can tap into my bubbler line by drilling a hole in the PVC and running lines where I want them. I'm wondering about the pressure though.....will that be an issue? I would be tapping into the bubbler line that runs from my lemon tree to my mesquite tree.....it runs under the flowerbed I want the drips to go. Does this sound feasible? Thanks

You are all probably going to fall all over yourselves laughing at me, but couldn't a couple of rain barrels be set up to handle some drip irrigation? Would a minimum of two barrels connected together maintain enough pressure to water a small (10'x10'?)flower bed? cora
