Help needed with shower/tub valve

[John Rousch]

I have removed the sink and replaced the faucet and extended the supply lines lower so the shut off valves can be accessed from the rear door. I have water coming through the valve assembly of the shower/tub to the sink faucets, but no water to the shower tub. This old plumbing is a nightmare, but I'm working through it. Pictures attached.

Finally everything is repaired using Shark-Bite and Pex tubing and putting in a new valve. I screwed the sink back in instead of rivets in case I need to get to the lines again. I dropped the shut-off for the sink lower so I could get to it from the rear door. Not too pretty, but everything works and doesn't leak.

Hard to tell the flow path but those two lines going down to valves that are white plastic with glue joints, you should replace that with same pex system in the rest of your work.
that blue glue is terrible and not meant for hot water, the only pvc rated for hot water is cpvc and it's specific glue.

Will do, thanks

Nice work. My bath is still a complete wreck, so I'm jealous that you're making progress.
