Why is my HTV107 leaking from the inlet, and how can I fix it?

A:

The HTV107 with plastic inlet and plastic outlet is designed to provide a secure, leak-resistant connection when installed correctly. If water is leaking from the inlet, the issue is usually related to thread sealing, installation method, water pressure, or damage to the inlet threads or internal seals.

How to Properly Install and Maintain the HTV107

Applicable for Plastic Inlet & Plastic Outlet

• Seal the inlet connection

Apply Teflon® (PTFE) tape to the male threads of the water source before attaching the plastic inlet. Wrap the tape clockwise several turns to ensure a proper seal. Hand-tighten securely, then gently tighten further if needed. Avoid overtightening, as plastic threads can crack or deform.

• Install the outlet

Connect your hose or irrigation line to the plastic outlet. Ensure proper alignment and hand-tighten only. Do not use tools, as they may damage the plastic fitting.

• 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. Check the inlet connection carefully for leaks.

Why the HTV107 May Leak from the Inlet or Stop Working

• No or insufficient Teflon tape on inlet threads

• Cross-threading during installation

• Overtightening that damages the inlet 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 inlet threads

• Hand-tighten fittings; never overtighten

• Use new AA alkaline, non-rechargeable batteries

• Keep water pressure within the recommended range

• Drain and store the valve indoors during freezing conditions
