Hi everyone,

Art, thanks for the explanation. From what I see, tee fittings are NOT valves, just a way of distributing the air flow. If you use it to connect the bladder to the pump and the air release, I assume that the pump itself is airtight and acts as a air stop until you release the air with the schrader valve. Correct? (I'm using 6V Oken pumps).
Thanks,

Mauro,
Your assumption is correct, for all practical purposes. The Oken pumps have an average leakage of about .4 mmHg/minute, which does not cause any problem during the normal running times of model subs.

[color=#000000]Hi Art,

thanks for the quick and accurate response. The excellent airtightness of the Oken pumps is a great thing and simplifes a real lot the making of my custom bladders. I'll use a four-way fitting (one end glued to the WTC endcap, the other three hanging out) to connect all the bladders in the wet space of the sub and then I'll connect the main tube with the pump and the release vale using a tee connection. Simple and reliable, this way I'm not going to have to add another valve to the rubber bladders and this will minimize the risk of leaks.
One last thing]
