Choosing the right sprinkler valves for your irrigation system is crucial to ensuring proper water flow and pressure to your sprinklers. With so many options on the market, it can be overwhelming trying to determine which valves are the best in terms of durability, performance, and value. In this comprehensive guide, we will explore the pros and cons of various types of sprinkler valves to help you make an informed decision when shopping for replacements or installing a new system.
What are the Different Types of Sprinkler Valves?
There are a few main categories of sprinkler valves:
- Anti-Siphon Valves
- Electric Solenoid Valves
- Manual Valves
- Pressure Regulating Valves
Let’s take a closer look at each type and its key features.
Anti-Siphon Valves
Anti-siphon valves, also known as backflow prevention valves, are designed to prevent contaminated water from being siphoned back into the main water supply. They contain a spring-loaded seal that only allows water to flow in one direction.
Key Features:
- Prevent backflow contamination
- Spring-loaded seal
- Allow one-way water flow
Anti-siphon valves are mandatory in most areas for health and safety reasons. They provide an important layer of protection for your drinking water.
Electric Solenoid Valves
Electric solenoid valves contain an electromagnet that acts as a switch to turn water flow on and off electronically. When energized, a plunger lifts up to allow water to pass through. Solenoid valves are operated remotely using an irrigation controller.
Key Features:
- Electronic on/off switch
- Allow for automated control
- Require wiring to a controller
- Fail safe is closed
Solenoid valves make it easy to automate your sprinkler system and customize watering schedules. They often last 10-15 years when properly maintained. The downside is that electrical failures can cause sprinklers to get stuck on.
Manual Valves
Manual valves are operated by hand to turn water on and off. Common types are gate valves, ball valves, and globe valves. They are simple in design but require manual operation each time watering is needed.
Key Features:
- Manual on/off control
- Simple, durable construction
- No automation possible
- Require regular access
Manual valves are reliable and inexpensive. However, they are not well-suited for large, complex sprinkler systems or frequent watering needs. The labor involved makes them less convenient for residential settings.
Pressure Regulating Valves
Pressure regulating valves maintain optimal water pressure downstream to irrigation heads after the valve. They prevent pressure fluctuations from damaging sprinklers or affecting performance.
Key Features:
- Regulate pressure
- Prevent pressure spikes
- Ensure smooth water flow
- Protect sprinklers
These valves provide an added level of protection and reliability for sprinkler systems. They are especially useful when retrofitting existing plumbing with higher pressure than sprinklers are designed for.
What Are the Key Factors in Choosing Sprinkler Valves?
When selecting new valves, there are several important considerations to weigh:
Flow Rate
The valve must be sized to accommodate the flow rate in gallons per minute (GPM) required for the sections of your irrigation system downstream. This ensures adequate water volume can pass through when open.
Pressure Rating
The valves must be rated for the static and dynamic water pressure they will be subjected to. Household water pressure typically falls between 40-80 PSI.
Materials
Brass and plastic are common sprinkler valve materials. Brass holds up better for the long haul while plastic is more economical. Stainless steel is also very durable but expensive.
Seals & Diaphragms
For maximum longevity, look for valves with rubber seals and diaphragms rather than lower quality materials that harden over time. Internal O-rings should also be durable and chemical-resistant.
Power Type
For automated systems, choose between 24V AC or 9V DC power depending on your irrigation controller. Battery operated valves are also available.
Anti-Siphon Protection
Backflow prevention is a must for any sprinkler valve that will be hooked up to your main home water supply. Ensure codes are met.
Manual Control
Even if automating your system, manual bleed valves and shut offs are useful in case of malfunctions or for winterization.
Brand Reputation & Warranty
Established brands generally have better reliability and stand behind their products with longer warranties.
Cost
Stick to valves that provide quality and features you need for a fair price. Overspending on industrial-grade valves usually isn’t necessary for residential use.

FAQs
What is the average lifespan of sprinkler valves?
With proper maintenance, the average expected lifespan for quality sprinkler valves is 10-15 years. Higher-end commercial valves may last over 20 years.
How do I prevent hard water damage to my valves?
Regularly flush valves, use water softening systems, and install filters to prevent mineral buildup that can impede performance and sealing. Replacing seals and diaphragms can also help maintain water tightness.
What flow rate do I need for my sprinkler valves?
Add up the gallons per minute (GPM) or gallons per hour (GPH) required by all sprinklers downstream of the valve and size your valve accordingly. Minimum 1″ valves are typical for residential irrigation.
Should I choose brass or plastic valves?
Brass holds up better long-term but plastic is fine for residential use, more economical, and easier to find replacement parts. Stick with thick, reinforced plastics.
How do I winterize my sprinkler valves?
Blow out all water using compressed air, close valves, and remove solenoid actuators and bleed caps. Disassemble drainable valves to remove residual water from the valve body and prevent freeze damage.
Summary
Installing quality sprinkler valves designed for durability, performance, and ease of use will ensure your irrigation system functions smoothly for years. Conducting research on trusted brands like Rain Bird, Hunter, Orbit, K-Rain, and Irritrol will help you select the right valves for your particular water flow and pressure needs. Investing in robust backflow prevention and automated electric valves takes convenience to the next level while protecting your home’s plumbing. With proper seasonal maintenance, you can expect a decade or more of reliable service from residential grade sprinkler valves. The peace of mind of avoiding stuck-on zones and plant-wilting failures makes it well worth installing the best valves for your system upfront.
