Russian Typhoon Submarine

Bilge Pumps and Check Valves

I purchased two (2) RAM-45 Boat Savers W/Bilge Pumps from Tower Hobbies to be installed in my watertight containers. They can operate on 9 - 12 volts, and they have both an automatic water sensor and a light. I´m not sure if I´ll be able to see the lights when the submarine is underwater, but I´m going to install them anyway. If a leak develops while surfaced, the lights should be visible. Ok, now you´re wondering why have bilge pumps in a vessel that will be mostly flooded on the inside anyway? Whelp, because I wanted redundancy built into my systems. If my Failsafe Unit blows ballast upon detection of a leak, I wanted the water to begin pumping out immediately. If my Failsafe Unit doesn't work for some reason, hopefully the bilge pumps will work and pump the water out ... and keep pumping it out until the submarine surfaces.
	I also purchased two (2) TME High Volume Check Valves from Tower Hobbies to be installed on the bilge pump discharge tubes. They are made for smoke and/or fuel, but should work fine for water as well. Check valves are needed on the discharge tubes to prevent water from re-entering the watertight container. The tubes will be submerged in water outside of the watertight containers unlike a surface vessel where the tube exits the hull above the water line.
Here, you can see the: bilge pump and motor u-shaped water sensor wire battery leads (I´ve removed the 9 volt battery clip) light discharge tube with check valve installed Next Step - Part 1b - Automatic Depth Control (ADC-1), Automatic Leveling Control (APC-3), Missing Pulse Failsafe (AFS)
