Why is my TTV103 leaking from the outlet, and how can I fix it?

A:

The TTV103 with one zone, brass inlet, and plastic outlet is designed to provide a secure, leak-resistant connection when installed correctly. If water is leaking from the outlet, the issue is usually related to thread sealing, installation method, water pressure, or component condition.

How to Properly Install and Maintain the TTV103

Brass Inlet & Plastic Outlet

• Seal the outlet connection

Apply Teflon® (PTFE) tape to the male threads of the hose or irrigation line before attaching it to the plastic outlet. Wrap the tape clockwise several turns to help prevent leaks. Hand-tighten only. Do not use tools, as overtightening may damage the plastic outlet.

• Install the valve

Connect the brass inlet to the water source, ensuring proper thread alignment. Tighten securely but avoid excessive force.

• Install new batteries

Use new AA alkaline, non-rechargeable batteries only.
Use one battery brand and replace all batteries at the same time.
Do not mix old and new batteries or different brands.

• Test the valve

Turn on the water slowly and run a manual watering cycle to confirm proper operation and check for leaks.

Why the TTV103 May Leak or Stop Working

• No or insufficient Teflon tape on outlet threads
• Cross-threading during installation
• Overtightening that damages the plastic outlet or internal seals
• Worn or damaged internal seals
• Use of rechargeable, mixed, or low-power batteries
• Excessive water pressure
• Freezing damage

Tips for Reliable Operation

• Always use Teflon (PTFE) tape on outlet threads
• Hand-tighten plastic fittings only
• Tighten the brass inlet firmly but avoid excessive force
• Use new AA alkaline, non-rechargeable batteries
• Keep water pressure within the recommended range
• Drain and protect the valve in freezing conditions
