A: Our D46 hose end preset pressure regulator does have a specific direction of flow for it to operate properly. Your dripline must be connected to the ¾” Male hose threaded side of the pressure regulator only. If you have any other questions, please feel free to contact our technical service/product support at 1-800-322-9146.
A: It's about 2-1/2" in length.
A: idk the length, but the pressure gauge still says 60 psi, am I doing it wrong?
A: The pressure regulator length is approximately 2.5 inches from inlet to outlet threaded in FHT X MHT. If you have any other questions, please contact our technical service/product support team at 1-800-322-9146.
A: Yes, but the threads won’t match up. You’ll probably need to convert from national pipe threads to hose end threads
A: Yes, just keep your emitters within flow limits per valve.
A: I suspect this regulator is meant for city pressure in excess of 60 psi. My city service has a pressure regulator to prevent over pressurization and my drippers work just fine without the restrictor. As for converting an existing surface spray head to a drip circuit its no issue all you need is the 1/2 inch male adapter to a hose connection and run it straight up with the drip master line and side 1/4" feeder lines to water your plantings. They will get water as they need it whenever that sprinkler circuit operates. I did it on a previous home that had rusty well water and it kept the foundation from getting all stained yet watered the foundation plantings.
A: To convert an existing sprinkler ½ inch riser over to a drip system you would need this D46 pressure regulator as well as our Q59 conversion elbow and the C34 swivel compression adaptor. If you have any other questions, please contact our technical support/ product support team at 1-800-322-9146.
A: I don't believe so. It's a pressure regulator, not a "backflow device". You want Dig 100 psi Hose Thread Backflow Preventer. https://www.homedepot.com/p/DIG-100-psi-Hose-Thread-Backflow-Preventer-D45/100141547 Charlie
A: I am fairly certain this also serves as a check valve as well. If it doesn't, you can always install a cheap check valve on it too
A: You could if your using the low pressure hose and there is significant drop. However I would use a heavy duty garden hose to transport the water to the bottom of the hill and apply the regulator their. The fitting reduces my house 55psi to the 25psi easily.
A: The D46 is a pressure regulator that reduces water pressure down to 25 psi it does not stop water from flowing in the opposite direction like a check valve. We recommend using only one pressure regulator installed right on to your outdoor faucet before connecting your poly drip tubing.

A: Great question....If your hill is greater than 60 feet from top to bottom you might try this about 60 vertical feet below your main hose bib and the first pressure reducer. I do not use the pressure regulator and run mine on relatively level ground with no more than 8 feet of difference. My system runs at a house line pressure of 50-60 psi and all irrigation heads do super well and with better spread than if throttled back to 25 psi. Water density provides a pressure of 1 psi for every 2.31 feet of elevation...so, the pressure at 60' below the initial pressure regulator would be 60/2.31 + 25 = 50.9 psi for any drippers that are near that elevation and 25 psi for those that are beyond that regulator location. This may simply mean using drippers with a lower capacity rating in the areas where the pressure is higher if maintaining a uniform watering pattern is essential.
