Bathtub faucet stem removal
Hi,
I'm trying to fix a leak in my bathtub faucets and was expecting to unscrew the stem "holder" (sorry, I don't know the name of the part that the stem and the packing felt sits in) to replace the seat and washer. However, what I discovered was that there is no stem "holder" and that the stem and packing felt washer seems to be inside the valve body itself. I don't know what brand the valve is but the stem has "Repcal" stamped on it. I think it's an old Crane-Repcal stem.
1) do I need to remove the stem to fix the leak?
2) how do I remove the stem from the valve body?
Thanks!
