Replace galley faucet 43 Post

Has anyone successfully replaced the galley faucet? I so far haven't found anyway to remove the 1-1/2" stem nut. I have a basin wrench, but the spring loaded head is too large to get on the nut and clear the outer sink flange. I've got a 1-1/2 crows foot coming as my probable last resort.

The sink attaches to the counter underside. It has a surrounding metal frame, but I can't see any physical fasteners. It looks like the faucet was installed, the sink glued to the counter and then the counter installed?

Plumbers wrench/basin wrench is what I tried, the head is too large when expanded to grab the nut. I can only get one arm in the cabinet at a time to reach behind the sink so hammer & chisel wouldn't be an option.

I've looked at the plastic tubes but wondered if they are strong enough with the open profile (although I have no way to tell how tight the nut actually is). Also don't know if the current rigid copper tubes can be "tucked" inside compared to the modern small hoses. I've never seen a metal one, can you send a link to them? I need one about 12" long to be able to get below the sink basin bottom.

My crows foot should arrive tomorrow so can see it that works. The tube ones might still be useful to remove the old soap dispenser that needs to go away too.

Faucet still works and doesn't leak, but is cosmetically showing it's age and wife would like a pull-out sprayer. Being careful to make sure I don't get in a position where I have no working faucet for our next trip.

I've looked at the composite barrel wrenches. There are comments on them not being very strong and twisting. To get one on I'd need to cut the existing faucets integral lines and I'm hesitant to do that as it makes re-installation nearly impossible if I can't get the old unit out. I may get one and try it on the old soap dispenser first to see how well it works removing that similar nut.

The basin wrench I have won't sit flush against the bottom of the sink to grab the nut due to the downturn flange around the outside which you can see in the photo.

I tried that with the soap dispenser body but it didn't losen the nut, started grinding brass away. To try on the faucet I'd need to disassemble the top first as it has a swinging spout.

Eurika! Got the old faucet nut off with my hex-jaw channel lock plyers. Only slight brusing from laying across the cabinet shelf ridge. Should be able to disconnect the supply lines and remove the old faucet when I have a block of time next week. Ordered one of the composite tube wrenches anyway, will see how it works on the old soap dispenser fitting.

Old faucet nut was 1-3/8, not the the 1-1/2 of the new faucet so the crows foot I ordered was a bit too loose to do anything.

Galley done. Had to cut the old soap dispenser tube with sawsall as the nut gauled/jammed part way off. Head faucet probably tomorrow. "Should" be more straight forward.

Thanks to all.
