Common Questions

Is this full port or standard port?

Full port. The ball bore matches the 3/4" pipe ID, so the valve adds almost no restriction — the right choice for pump suction, main shutoffs, and any run where you cannot give up head.

Can I use this on natural gas or propane?

No. This valve carries no fuel-gas listing, and code requires an ANSI Z21.15 / CSA listed valve for natural gas or LP. Use a Watts GBV series gas ball valve instead.

Is this rated for potable water?

Yes. It is a lead-free model certified to NSF/ANSI 61 and NSF/ANSI 372, so it meets the Safe Drinking Water Act limit for potable-water service.

Can it be serviced without cutting it out?

No. A 2-piece body is not designed for in-line rebuild; it is replaced as a unit. Choose a three-piece valve (LFB6800 / S-6800 series) where in-line serviceability matters.
