Plumbing

All the plumbing parts arrived.  This has taken me a while to get sorted out, particually as I’ve had to work it all out. There are probably multiple ways fo doing this, but this is how I’m doing it. 

There are 2x scuba whips that will fit to scuba tanks using 232bar DIN connectors.  These fit to a manifold bar which has 2x DIN connector adapters.  On the side is a pressure regulator so I can adjust the pressure to whatever I like, up to full tank pressure.  I think this is probably not neccesery as the system is designed for full tank pressure anyway.  But, I want to use the regulator for testing some other things as well.  The hull check valves are at the top of the picture, plus 3x needle valves (top left) for the tank controls.  Right of the picture are the 2x pressure regulators for depth gauges.  One of these is a standard pressure gauge reading bar\psi, the other is the same but has a custom faceplate indicating meters\feet of seawater.  They are chemical protected gauges. 

Also in the picture are the various high pressure connectors, adapters, T’s, check valves etc which are all fairly straight forward. 

At the bottom right there is the Fuller pressure gauge which I am going to modify to read internal cabin pressure by adding a reference bottle.  I spotted one of these on the back of a sewage tanker and noted that it reads +\- 1 bar pressure with the needle in the middle.  I tracked one down on the internet.

Top left is the 320 bar 6mm and 1/2 inch pipe that will make up the system.

Large valve in the middle is the hull flood valve which isnt really part of the plumbing system.
