Bathmate mod

is that just for convenience? Keeping the cork attached? I wanted to secure mine into a 1” Inside diameter tubing and press it against the valve instead of going over top of the valve of the hydromax just in case I can’t release the pressure. 🤷‍♂️
Try it! I have always thought about that.
 
The VaccuVin mod works.

How to:
1. Remove the replacement valve carefully with this tool:

2. Then you have this: Top part of the pump.

It's now a hole right through.

3. Tape with Gorilla tape and electrical tape, to make it so, that you can't compress the spring.

4. Put the cork for the VaccuVin pump in place instead of the Bathmate valve.

4. Tape with electrical tape and self-vulcanising tape/self-fusing tape, to make it vaccum tight and water tight.

That's it. Now you can go beyond the original max vaccum/pressure. Be careful.

Here is how it looks like:

I don't know how long the cork are going to last, so in the future you can put a pvc tube, or maybe pipe between the Bathmate and the cork. In that way it's easy to replace the cork.

Hope this helps.

you can also keep the BM 'as-is' and just slide a short piece of PVC to act as a connection point for the VV pump...no need to dismantle anything and no need to use the VV cork
