Product Information
Full details
The Claber Threaded Drainage Valve (91037) is an essential component for gardeners and landscapers utilizing drip or micro-irrigation systems. It is designed to automatically evacuate water from low points within an installation, effectively protecting your irrigation infrastructure from freeze damage during the winter months. While it is highly effective for seasonal maintenance, users must ensure it is installed at the absolute lowest point of their circuit to ensure complete water drainage.

FAQs
Does this valve require electricity?
No, the Claber Threaded Drainage Valve is entirely mechanical and operates based on hydraulic pressure.
Can I leave this valve installed year-round?
Yes, it is designed to be a permanent part of your irrigation circuit and functions automatically based on water pressure.
What happens if the valve gets clogged with dirt?
If the valve is buried, it is recommended to place it inside a small gravel bed or valve box to prevent soil from blocking the drainage port.
Is this compatible with standard garden hoses?
It is designed specifically for micro-irrigation circuits. While it may thread onto some components, it is intended for low-pressure drip systems.
How many valves do I need for my garden?
You should place one valve at every significant low point in your irrigation circuit where water is likely to pool.
Troubleshooting
Valve continues to leak while system is pressurized
Check if there is debris stuck in the valve seal. Remove the valve and rinse it with clean water to clear any sediment.
Water is not draining after the system is turned off
Verify that the valve is installed at the lowest elevation point. If it is located on a raised section of tubing, water will not flow out.
Pros and Cons
Pros
- Prevents costly winter freeze damage
- Easy to install in existing irrigation circuits
- Requires no manual intervention once set
- Compact design fits easily into valve boxes
Cons
- Requires precise placement at the lowest elevation to be effective
- Not suitable for high-pressure main supply lines
- May require periodic cleaning to prevent sediment buildup
Setup, Compatibility & Care
To install the valve, identify the lowest point in your drip irrigation layout. You will need a threaded tee or a corresponding adapter to insert the valve into your hose line. Hand-tighten the valve to ensure a secure fit, but avoid overtightening with tools to prevent cracking the plastic housing.
Compatibility is highest with Claber micro-irrigation products, though it will fit any standard threaded connection matching the valve specifications. For maintenance, check the valve once per year at the end of the season. Ensure the small exit port is free of soil, dirt, or mineral deposits that could prevent it from closing or opening properly.
