Today I continued addressing leaks and ran into a couple of minor issues. Although I was able to stop the leaks on the water and steam taps, the material I have doesn't immobilize movement of those fittings, and it's soft and can break free, which has clogged the steam valve/wand. I've searched this site and find that others suggest Loctite 567 as a thread sealant approved for drinking water. Perhaps someone who has used that can tell me if it will also "lock tight" the position of the fitting and be removable with a couple of wrenches and hand strength. The alternative seems to be PTFE tape, but it's tricky to get just the right number of wraps to hold the fitting where you want it.
If the steam and water taps aren't quite right the group needs to be removed to turn them out. It's not all that hard, just requiring removal of four nuts and lifting out the 14+ lb. group (lever not included).
Here's where a leak still remained, at the junction between the long steam stem and the valves that are outboard of that.
I hadn't installed the copper crush washers that are in the exploded parts diagram as items 1813.
Here's where that should fit,
and the copper washer added.
I also addressed the leaks in the connection between the steam wand and water wand and the valves. This was a flat surface requiring gaskets.
I punched two Teflon gaskets. Here's one added.
I also applied Loxeal, a soft thread sealant. The fitting tightens down onto the gasket, so the thread sealant doesn't need to hold it in position.
Water comes out of the water tap, but it carried some loose Loxeal. No steam exited the steam tap, so I'm assuming it's clogged with loose Loxeal and will need to clean that out. I'll disassemble tomorrow, clean that out and try PTFE tape to hold these valves in place, since I don't have any Loctite products on hand and these aren't items you can get at any local hardware store.
The other roadblock I ran into today was when I examined the edging I'd ordered for drip tray grate fabrication. The eBay description didn't mention that it's punch for screw holes or that the side I want to have on top has manufacturing marks all along it. I'll return this item for a refund.
