Hi, I'm trying to help out my father, the Hot faucet broke and is leaking an needs to be replaced. He believes it's just the valve but the company is no longer in business so we're thinking to replace both faucets. I've gotten this far, but not sure how to remove the actual faucet. I see a large "nut" toward the bottom, but unsure if that's what I need to turn. Any insight is appreciated. I can probably track down the manufacturer name even though it's out of business if that helps with troubleshooting. Getting below is possible but not easy as it sits above a crawl space/shed. Thanks for any info.
