Hello, can you explain what is the difference between the non-positive and positive seal diverter? Do you carry positive and non-positive generic items?

Hello Ray - Thank you for contacting Inyo. Below is an explanation of the difference between positive and non-positive seals.

  • Positive seal – Completely seals the valve opening preventing any seepage. The diverter gasket is more robust and protrudes from the face of the diverter to create a firm seal.
  • Non-positive seal – Allows some water to pass through the diverter when closed, making it not ideal for standard plumbing use. Non-positive valves are normally found on systems with solar heaters so water can drain from the solar panels even when a valve is set to “CLOSED”.

We have positive seal generic parts.
