We are an FRC team. Its just that the account that we are using right now is the one we used last year when we were an FTC team . Sorry about the confusion.

I'm curious about what you have plugged into the B ports on the left side, and why there aren't corresponding tubes in the A ports. Also, are you feeding air into the threaded "P" port on the side of the manifold not shown in that picture?

Can you tell which exhaust the air is leaking out of? EA or EB? If you manually trigger each solenoid, does it switch which port it is leaking out of? This would be a way to narrow down which part of the circuit has the problem.

If I were trying to fix this I would unscrew each solenoid and wipe off the gasket and the mounting surface, then carefully re-mount them, alternately tightening the two screws to reduce the chance of the solenoid sitting crooked. We have also had the rare instance where the solenoid was leaking internally.

I'm not exactly sure if there is a leak. It seems that we are only able to control the A ports on the solenoid. We are not able to control the B ports, so the air keeps leaking out of there and makes the A ports useless.

Here is our code. Let us know where we are making a mistake:

package org.usfirst.frc.team6560.robot;

import edu.wpi.first.wpilibj.Compressor;
import edu.wpi.first.wpilibj.IterativeRobot;
import edu.wpi.first.wpilibj.Timer;

import edu.wpi.first.wpilibj.*;
import edu.wpi.first.wpilibj.smartdashboard.SendableChooser;

*/
public class Robot extends IterativeRobot {
   static final long TIME = 10000; // ms
   static final int SAMPLE_COMPRESSOR = 0;

   Compressor sample_compressor;
   long m_autoStartTime;
   long m_autoStartTime1;
   long m_autoStartTime2;

   Solenoid solenoid_0;
   Solenoid solenoid_1;
   Solenoid solenoid_2;
   Solenoid solenoid_3;

   public void robotInit() {
       sample_compressor = new Compressor(SAMPLE_COMPRESSOR);
       solenoid_0 = new Solenoid(0);
       solenoid_1 = new Solenoid(1);
       solenoid_2 = new Solenoid(2);
       solenoid_3 = new Solenoid(3);
   }

   public void autonomousInit() {
       m_autoStartTime = System.currentTimeMillis();

   }

   public void autonomousPeriodic() {
	   
	   solenoid_0.set(true);
	   solenoid_1.set(true);
	   solenoid_2.set(true);
	   solenoid_3.set(true);
       
   }

}
