Zodiac intercommunicating VALVE question
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.
