Zodiac intercommunicating VALVE question

[Dolphin60]

I just purchased a 550 SRMN

It has 4 chambers.
The front pumps up fine
the middle chambers pump up fine

The rear cones do not get any air

I was reading about some kind of "intercommunicating valve" system.

Does anyone know what the procedure is to direct air into the cone chamber?

I ran the boat for a pacific sunset and it runs amazing.
Just the rear cones are flat.

Any help or education on how this works
The sellers did not know anything.

Thank you in advance on the proper way to inflate the cone section of the tubes.

if i'm reading this right the back chambers either side will not inflate it can't be just the tapered cones, the chambers should all be separate, this will sound silly but have a look round for another pair of valves or failing that get another pair glued onto the flat chambers east enough to do

There should be a setting on the valves that you can turn the outer valve to. Im sure someone will be by shortkly with more info and even a pic of what Im trying to explain

The SRMN 550 has 5 air chambers and 4 intercommunicating valves. Each valve has an inflate and navigate setting. Inflate will open the valve allowing air to flow between chambers, navigate closes the valve creating separate air chambers. With every valve turned to inflate the boat should inflate from cone to bow.

Thanks to all

CAH also big help. Turns out the valves were frozen from sitting. This is the first time I have seen that set up. It works. Boat is full and well...........its been a long day of fun.

Problem solved. Thanks to all
