Glass Check Valve/Bubble Counter

As i see the bubble counter is a copycat of Dazs which is a copycat of ADA
The BC would work.

The check valve i am not sure about. i only have bad experiences. This is the same cv as Dennerle sells to their crystal set. This fully leaks the water. I would never buy this.

 

yeah,with mine the bubble counter loses water and the check valve doesn't work.
managed to break both so no longer a problem .

 

That you being heavy handed. hands like pan shovels
paul.

 

i use the ADA check valve. This is the cheapest ADA product i guess
You can get it from TGM probably.

This is how it looks:
