Questions about this item

How can I confirm the 800-245 HI-CAP air vent is venting properly after installation?

After fitting the vent to the T-88 or HS-808 body, run the system and watch for a steady release of air followed by a firm shut-off; the internal check valve should then hold pressure without leakage.

What comes with the 800-245 HI-CAP air vent and what must I source separately?

The package contains the replacement high-capacity air vent assembly with its built-in check valve; you will need to supply the T-88 or HS-808 main body and any pipe fittings or thread sealant required for your installation.

Which Legend Valve air vent version matches my existing T-88 or HS-808 unit?

The 800-245 HI-CAP model is the direct replacement for both the T-88 and HS-808 series; choose this part number when your current vent carries either of those designations.
