Hi, I'm not sure if I'm posting the right way.
But.

I recently found out that my bezzera bz07 was leaking water.
When I opened the machine I noticed that the pump valve was lose.

I disassembled al the parts and thightend it. I also readjust the red circled part on te photo to get the valve in the right position.

Now in notice that that part is leaking a bit of water.

What can I do? Use teflon tape or need I buy new parts?

Regards!

I would certainly try teflon tape, before replacing the fittings.

Seems like the teflon works. Thanks

Now wait for a new PID to get the machine back running again.
