Bubble Purge G2, Bubble Purge Pro SC and DC FAQs:

Bubble Purge G2- My kit does not have the short section of tubing with female couplers:

We eliminated the short female to female section in the second generation “G2” kit.  The new G2 kits have a short section of tubing with male fittings on both ends.  This section of tubing is only used for system flush (connected to the end of the cylinder attachment) or for a quick helm fill (connected directly into the bottle cap and used like as a squeeze bottle) as seen in the G2 demo video on YouTube. 

Why does the G2 listing say it is not intended for systems with power assist or autopilot?

The Bubble Purge G2 basically converts the steering system into a large circuit, pushing air and fluid back through the steering hoses into the helm where it will vent through the helm fluid reservoir.  This process can be problematic for more complex systems because once a power assist pump or autopilot pump is purged, you do not want to risk re-introducing air into the pumps as the air is pushed through the hose on the way back to the helm.  The Bubble Purge Pro Kits are recommended for these types of installs because they vent air out of the system back at the steering cylinder through a return hose that runs above decks, drastically shortening the ventilation process and eliminating the risk of reintroducing air into a fully purge pump.  The return hose on the Pro SC and DC kits is also compatible with any SeaStar external bleed fittings which are built into several models of Auto and Power Assist pumps.

I have dual cylinder with liquid tie bar, which kit is best?

We recommend the Bubble Purge Pro DC for this type of system due to the way the system is configured.  The above decks return hose allows the Tie Bar Valve to be opened and both cylinders purged simultaneously.  This creates a much more efficient path to purge air and eliminates the possibility of chasing air from one cylinder to the other which can happen with purge systems designed for single cylinder use only.  

What do I do with the fluid remaining in the Bubble Purge hoses once the purge is done?

If the fluid remaining in the Bubble Purge hoses is clean, you can simply connect the hose ends to each other, this will seal the unit off, preventing any leaks and store the Purge kit in a safe dry spot our of direct sunlight.
