Rain Bird’s Seal-a-Matic Check Valve Explained

The Rain Bird 5000 series of rotors are some of our most popular. In this video, we’re going to talk about Rain Bird 5004 PC Seal-a-Matic Rotor, tell you what the Seal-A-Matic does, talk about the other features as well, and show you how to change out a nozzle and make some adjustments. I’m Dwayne Smith. Your Sprinkler Warehouse Product Specialist.  Let’s get started.

This is the 5004-PC-SAM Seal-A-Matic Rotor. Rain Bird rotors with SAM in the name have a Seal-A-Matic check valve that prevents low head drainage. If there is a significant elevation difference within a zone, once the sprinklers shut off, the lowest head often drains the water out of the piping within the zone, which results in puddling and erosion. The Seal-A-Matic check valve on the 5004 holds up to 7 feet of elevation change.

Changing The Arc On Rain Bird 5004 Rotors

The PC in the name stands for partial circle. That means you can adjust the arc, also called the pattern. You can adjust the pattern on this rotor from 40 to 360 degrees. The popup height on this rotor is four inches and it has a three-quarter inch inlet. 5004 rotors have a watering distance of 25 to 50 feet depending on which nozzle is installed and how the adjustment screw is set. The 5004 series have what Rain Bird Calls “rain curtain” nozzles. This rotor comes with this set of Rain curtain nozzles.

These nozzles have a very even spray over their entire distance and larger water droplets. Larger droplets mean less water gets carried away by the wind and more water ends up at your plants’ roots. The 5004 series rotors have superb longevity. Rain Bird rotors have the longest operating life cycle of any rotor on the market. To adjust the rotor, you can use a rain bird tool like this one or a small flathead screwdriver. Looking at the top of the rotor. This is the radius adjustment slot.  This adjusts the watering distance. This is the pull-up slot. This is the arc adjustment slot. That affects the pattern. Let’s go outside and check out the adjustments.

How To Change The Nozzle On Rain Bird 5004 Rotors

We’ll begin by changing out a nozzle. Insert the rain bird tool in the pull-up slot. Twist. And pull up. I’m using a Hold-up Nozzle Install Collar to hold up the riser to make it easier to work on it. But if you don’t have one you can hold it up with your hand. Back out the radius adjustment screw. Pry out the nozzle with the rain bird tool or a small flat head screwdriver. Insert the new nozzle.  The divot that accepts the radius adjustment screw goes up. And thread back down the radius adjustment screw.

Turn on the water to your system and use the radius adjustment screw to set the watering distance. You want the water from this head to reach the next head over. To adjust your arc, also called the pattern, insert the rain bird tool or a small flathead screwdriver in the adjustment socket. And turn it clockwise to increase the arc or counterclockwise to decrease. You’re going to love working with the 5004-PCs.  They’ll give you year after year of solid performance.
