Shower Stem Valve drips (NOT the head, the valve)... Even after installing new seat and stem

[edom31]

Greetings folks...
So my Hot water shower valve stem dripped when on... So I decided to change it.
Installed a new one, seat and all, and it continues to drip (maybe dripping "harder").
Only hot water, but odd that when cold water valve turns on, it also drips = but drips cold water (through the hot valve...
Any thoughts?

Video of what it looks like:


Thanks!

Remove the handle and snug up the nut at the end that the stem passes through. Those are often not tightened up enough when in the kit. Always check that before installing handles.

The Bonnet I think is called, right?

Yup... tightened it and voila. I just hope not to over tightened it.

Thanks!

I put some effort into illustrating what I wanted to relate. I was frustrated at that point... Thank you!

That’s the packing nut. The packing nut screws into the bonnet. The bonnet screws into the valve.

The packing gland gets compressed by the packing nut around the stem to stop leaks around the stem where it passes through the bonnet.

The bonnet has a cap gasket or oring acting as a cap gasket to seal the bonnet to the valve body.

The cap gasket on your price pfister verve model is plastic.

It uses a 3/8 large Bibb washer.

I can literally rebuild that faucet blindfolded
Yes, I did it to say I can do it.

I just rebuilt one last week, not blindfolded though.
