Screw it in - it's as easy as that.
I needed a drip system for my roses, there was a high pressure sprinkler close by, so by using this product I was able to reduce the sprinkler pressure to a drip level. I use this product with a 4 outlet drip emitter.

Retrofit Pressure Regulator
Works perfectly! I get enough pressure throughout the system and then it reduces the pressure for the local spot. Perfect!

Work well but have been difficult to find
I have used these pressure regulators before and they work very well. However, they have been difficult to find so I was happy to find them on line and at a good price.

Great Product
I'm using rectangular center-strip heads in a long vegetable-garden planter and our water pressure varies so much that one day the ground is wet several feet outside the planter and another day it's barely damp in the center of the planter. These regulators solved the problem. My only wish is that they were much shorter since they're designed to be an extension to existing risers that should already be the proper height above ground. As a "retrofit part", wouldn't most people want them to have minimal effect on the height so that they didn't have to dig-up and replace the risers? They're still a great product.

Great for converting to drip irrigation
Perfect item to replace an existing high flow sprinkler and drop the pressure to a value appropriate for a drip irrigation system.

Looking good so far.
I converted my surface drip irrigation system to a deep root drip irrigation after noticing root ball movements during a heavy wind storm. Using this pressure compensator, I added drip emitters to the ends of ¼" hoses. I routed the hoses to the bottom of 30 in deep roots spikes. I'm hoping this works to help my tree develop better anchor roots.

Almost perfect
Once I put a better rubber washer in it to keep it from leaking it worked great!

What is the female end like? Is it a compression fitting that I can directly stick my drip line into or is it threaded? Is it 1/2 inch size? Is the male end that is threaded 1/2 inch size? thanks.
Louise C on Jan 4, 2012
BEST ANSWER: threaded
I have installed this pressure regulator on a riser. After the regulator I installed an barbed elbow fitting to which the 1/2 inch tubing is attached. There is a strong stream of water coming out of the indentation (which is covered with a small rubber O ring). The indentation has a tiny hole in it under the O ring. Why is this happening and why is the hole there?

Do you have this type of inline pressure regulator with 1/2 inch barbed fittings on both ends?
Gary R on Jun 20, 2016
I bought a Rain Bird drip irrigation kit. The irrigation kit comes with a faucet connection kit that includes a pressure regulator and a backflow preventer that includes a mesh filter.

My plan is to put a Y-splitter at my outside faucet and attach a plastic hose to one of the Y outputs that will lead to my garden, at which point I will attach my 4-zone watering timer.

I haven’t done this before. I anticipate some problem fitting the 1/2 inch black drip irrigation tubing or brown irrigation tubing with built-in emitters onto the 3/4-to-1/2 inch hose adaptor. Should I put the tubing under hot water to make it more pliable and easier to fit the tubing onto the adaptor?

I am not sure whether to break up the assembly of backflow preventer, pressure regulator, and hose to tubing adaptor or install it inline all together. It makes sense to me to have the backflow preventer on the faucet side of the timer and the pressure regulator with hose-to-tubing adaptor together on the tubing side of the timer. That way each zone will be pressure regulated separately. If that is the case, I will need three more pressure regulators with 3/4-to-1/2 inch hose adaptors. How can I specify these properly and do you sell them?

which end in the inlet?
A shopper on Oct 24, 2015
BEST ANSWER: I use this device to reduce the pressure of 0.5 inch sprinkler head riser from ~70 psi to 30 psi.
The female end screws into the male fitting (after the riser is removed).
Hope this helps.
Does this work with Hunter risers?
Gail M on May 30, 2017
BEST ANSWER: As far as I can tell they work. I have not had any drip heads split since I added the risers.
Hi, I'm trying to set up an automatic watering system for my container garden. I'm using Hydro Halo 6" rings connected to 1/2" poly tubing. The problem is a lot more water gets to the first plant in line compared to the last plant. Only 9 plants running off of 50 feet of hose with a 285 gph pump. Can I use pressure regulators at each site to fine tune?
Paul W on Feb 19, 2015
BEST ANSWER: Friction loss would explain this if it was a long run, but it's only 50 feet. My only other thought is if your hydro halos emit alot of water that the pressure in the line can't buildup to a contstant level and perhaps your PSI is lower because of the well situation?. That could compound the situation. I run a standard drip system retrofitted to sprinkler risers. Pressure regulators are recommended as standard house water pressure is usually about 60 PSI and the drip line and emitters like closer to 20 PSI. You are on well it looks like so I can't comment on your PSI.
which is inlet side FTP or MPT?
A shopper on May 18, 2015
BEST ANSWER: Inlet or full pressure side is the female threads(larger end). Male threads shown at top of picture are the reduced pressure side. These are useful for replacing a pop up sprinkler with the pressure regulator and topping with the Rainbird XBD-8 drip irrigation head.
