Pressure regulators

Excessive water pressure can damage a sprinkler or drip system of irrigation. A pressure regulator is used when the incoming water pressure from a source is too high for the emitters or irrigation fittings. The regulator reduces it to a set, usable pressure..

Regulating pressure also saves water and extends the life of the irrigation system. Saving water is achieved through regulation by operating each zone at the best pressure for that equipment and application type.

Here’s a roundup of the pressure regulators we offer:

Hunter - Accu-Sync Adjustable Pressure Regulator

Accu-Sync is a simple pressure regulator designed to be compatible with all of Hunter’s sprinkler and irrigation control valves. The adjustable model enables the zone pressure to be set anywhere between 20 and 100 PSI, while fixed models remove the guesswork and can be installed throughout any system easily. Glass-filled nylon construction makes the Accu-Sync strong enough to handle the rigors of any project. No matter which model you choose, all zones stay in tune with Accu-Sync.

We also carry Hunter ACCU-SYNC water pressure regulators with fixed PSIs:

Hunter - ACCU-SYNC Regulator - 30 PSI

Hunter - ACCU-SYNC Regulator - 40 PSI

Rain Bird - PRS-Dial Adjustable Irrigation Pressure Regulator

The PRS-Dial is an excellent means of regulating outlet pressure at the valve, regardless of incoming high-pressure and low-pressure fluctuations. The visible scale makes adjustment quick and easy. The regulator fits all Rain Bird PGA, PEB, PESB, PESB-R, GB-R, EFB-CP-R, BPE and BPES series valves.

  • Improved spike reduction capabilities reduce water hammer
  • Ergonomic design with snap-tight cover prevents vandalism
  • Waterproof dial cartridge eliminates fogging and binding
  • Dial cartridge retrofits into all existing PRS-D units
  • Visible scale makes adjustment quick and easy

We also carry assembly kits for Irritrol’s OmniReg® water pressure regulators for irrigation and sprinkler systems. OmniReg® allows the user to quickly and accurately set the exact downstream pressure required for any application. It maintains constant downstream pressure, regardless of widely varying inlet pressure. One model fits all heavy-duty commercial 100 Series (Century PLUS), 700 Series (UltraFlow®), 200B and 311A Series valves. Requires only 1 GPM to operate.

Options include:

Irritrol - Reg Assembly Kit 30PSI Turf

Irritrol – Pressure Regulator Assembly Kit 100 PSI Turf

Reinders also carries pressure regulator products for irrigation by Toro.

Among them:

Toro - EZReg, 5 to 100 PSI Regulator Module For P-220 Series Plastic Valve

An accurate and visibly adjustable dial, coupled with a forward flow valve design, allows the 220 Series to work with the EZ-Reg module to regulate with precision. It can regulate with flows of only 5 GPM (1" valve) and only requires 10 PSI differential to operate.

The pressure regulator is perfect for retrofit irrigation and sprinkler projects. It can be easily and quickly installed -- even under pressure, with no danger of water geysers from the removed solenoid area or opening of the valve. The EZReg regulates in the manual mode, should power be unavailable. A standard, Schrader-type valve permits quick verification of downstream operating pressure.

We also carry pressure regulator modules for use with Toro’s P-150, P-220 and 220 Series valves:

Toro - Pressure Regulator Module 0-30PSI

Toro - EZReg Module 5-30 PSI

Flow sensors for sprinklers

Flow sensors measure how slowly or quickly water is flowing from a source through a sprinkler system and send that information to an irrigation controller. This is incredibly helpful in detecting issues and conserving water. In addition to monitoring flow rate, flow sensors can detect unscheduled, low- or high-flow events.

Toro - SEN-FLO FSI-S40-001 PVC Saddle-Type

This saddle-type sprinkler flow sensor by Toro has a two-wire output in a 4-inch PVC saddle mount.

The FSI-S Series sensors include the mounting saddle. Sensor depth and alignment are pre-set. No measuring tools and alignment rods are necessary. Simply drill a 1 ¾-inch hole in the pipe and attach the two halves or the saddle.

We also offer a broad range of products for Toro’s TFS flow sensors. These sensors offer effective flow monitoring, even in flows less than 5 GPM. It’s effective in ranges from 1.2 GPM to 500 GPM. Teamed with the Toro TMC-424's ½”, ¾” and 1” sensors, they provide a cost-effective flow monitoring and alarm system.

Toro’s TFS sprinkler flow sensors are compatible with Toro and competitor controllers that work with frequency-output flow sensors.

We offer the following options:

Toro - Flow Sensor 4" Plastic Tee

Toro - Flow Sensor 3" Plastic Tee

Toro - Flow Sensor 2" Plastic Tee

Toro - Flow Sensor 1"Plastic Tee

Toro - Flow Sensor 3/4" Plastic Tee

Toro - Flow Sensor 1/2" Plastic Tee

Automatic drain valves

Every sprinkler or irrigation system should have an automatic drain valve. They prevent irrigation pipes from freezing by automatically draining sprinkler lines when the water is turned off. Having an automatic drain valve will also keep water from sitting in the pipes. Automatic models don’t require your sprinkler system to run any kind of emptying process to drain the water.

Need an irrigation automatic drain valve? We’ve got those, too!

Among our many options:

King Innovation’s 3/4" Automatic Drain #23167.

For use on both main and lateral line applications, this automatic drain complements end-of-season blow-outs to remove residual water from irrigation systems and provide freeze protection. The raised screen prevents clogging of drain due to sediment and/or contaminants.

Other features include:

  • Patented pressure-sensitive valve - releases water slowly at root level.
  • Patented backflow check - eliminates potential freeze damage and backflow contamination by preventing water from re-entering the system.
  • Soft-grip ergonomic design with non-corrosive housing – allows for better torque and easy, comfortable installation.
