Orbit 67798 — 30 PSI Pressure Regulator + Filter 3-in-1 (1" MPT)

What is it and what's it for?

It's a fitting that screws in between the spigot and the drip tubing, and 'holds back' the water pressure before it reaches the emitters — think of it like the regulator on a propane tank, which keeps the flame from roaring out of control even though the tank itself holds a lot of pressure. A home's water mains typically run 40 to 80 PSI, far more than a drip kit (rated for 20-45 PSI) can handle without breaking.

Real-world use cases

• At home: You installed the Bonviee or MIXC drip kit from this site and notice some emitters spraying water forcefully instead of dripping slowly — the kit isn't defective, your tap pressure is simply higher than it's rated for, and this regulator fixes that at the inlet, before water ever reaches the tubing.
• In a business or workshop: A nursery connecting several drip lines to the same high-pressure spigot can install one of these regulators on each outlet so every line gets an even 30 PSI, instead of the line closest to the tap getting too much pressure and the farthest one too little.

How to avoid buying the wrong one

• Check your spigot or valve's thread size (this model is 1" MPT) — if your setup uses 3/4", you'll need the matching version or a separate adapter.
• It already includes a sediment filter, so you don't need to buy one separately — it protects the emitters from particles that could clog them over time.
• It regulates to a fixed 30 PSI, not adjustable — confirm that's within your drip kit's supported range (the Bonviee kit in this ranking, for example, handles up to 45 PSI, so 30 PSI fits fine).
