No Issues
No issues. Exact replacement of existing relief valve on furnace. Works well (no leaks) with teflon tape - no need for pipe dope. Word of advice... Unless your furnace is pristine, I wouldn't flip the relief valve lever after installation to test the valve. Any crud in your furnace water might work its way into the valve and cause the valve to leak, and then you'd have to flush the valve or clean it. I'm not saying to never test the valve, just leave it for your yearly maintenance.

Great value
Way less expensive than any local supply house or big box store. Stopped an annoying drip on my boiler without compromising safety.

good price , my backup relief valve
I bought this pressure relief valve as an emergency backup for my present valve. Other than a lower BTU rating, this one is similar to my current relief valve.
