Water Relief Valve 3/4 Inch 30 psig

This Conbraco Industries valve protects water heating equipment by releasing excess pressure. It is rated at 30 psig with a 535000 Btu capacity. The component fits standard three-quarter inch connections. It is sold individually for professional or residential plumbing installations.

Suits installers needing a code-compliant relief

The valve serves systems that require pressure protection at the specified rating. It is not intended for steam service or applications exceeding the listed pressure and Btu limits. Buyers who need a different pressure setting or a larger inlet size must select another model.

30 psig pressure setting with 535000 Btu rating

This single specification determines whether the valve matches the equipment it is meant to protect. The pressure setting must equal the system design pressure. The Btu rating must equal or exceed the heater input. Verify both numbers before purchase.

Questions about this item

What thread size must the existing pipe have to accept the 3/4 In. valve inlet?

The valve has a 3/4 In. connection, so the mating pipe or fitting must provide a matching 3/4 In. thread for a secure fit.

Will the 30 psig relief setting protect an older tank rated for a lower working pressure?

The valve opens at 30 psig; if the older tank's maximum allowable pressure is below 30 psi, this valve would not provide adequate protection.

After installation, how can I confirm the valve is operating at the 535000 Btu capacity rating?

The 535000 Btu rating reflects the valve's discharge capacity; verify correct operation by checking that water discharges when system pressure reaches 30 psig during a test.
