Matej You have bought great regulators. The problem is likely to be one of two things: * Too high an inter-stage pressure, Apeks recommend 9.5 + /- 0.5 bar, though an lower inter-stage pressure is fine. * A faulty batch of high pressure seats which are leaking, thereby increasing the inter-stage pressure to increase. The second stage in both instances is acting as a over pressure valve.

Between our friends we have 5 Tx40 regs. They seem to have some sort of problem with 1st stages. They leak slowly (we swapped the 2nd stages and it did not help) so that you have continuous small stream of bubbles coming out of the second stage. That happened in 2 cases. We decided for Apex based on the list recommendations and we took membrane dry 1st stages because we frequently dive in cold waters. Both leaking regs are well maintained and almost new (in fact one came leaking new) and the other has less than 20 dives. The rest of us are now very worried. (because we thought we bought good regs...) 1) Is this common for TX40 (TX50 has the same 1st stage) and what shall I do. 2) What is the cause of this/how to solve it.
