Question about Campbell Hausfeld 2 - Gallon Direct Drive Air Compressor

Campbell Hausfeld air compressor is sucking air from pump output

Hello,
I picked up a campbell hausfeld air compressor from an estate sale. Its an electric 2hp with 2 small stacked tanks ,4 gallons. I think the model isHL550700 , not sure. as far as I can tell its only missing the regulator. There is a copper tube that comes from the bottom tank and is disconnected in the area of the air pump outlet. I am guessing maybe it went somehow to the regulator and or the pump outlet on the head of the air pump. It looks to be about 3/8 in. dia. or so. There is not a fitting in the air pump outlet but it accepts 3/8in pipe thread. Also, the fitting on the bottom tank tees off with a 1/8 in. or so copper tube and is connected on the side of the electric pressure cutoff switch to a little relief valve.
So after looking the unit over I decieded to plug it in to see if the motor and pump work. The motor ran fine but the pump was sucking air into the out put of the pump and blowing it out the air intake valve on the head. It was a pretty strong suction but wouldnt be any good for blowing up a tire.

Just for the heck of it I pulled the head off and reversed it but it still did the same thing. Unfortunitly I cant get any history on the unit but someone pulled the regulator off for some reason.

So do I need a valve for the pump? I put my finger on the pump air out with the motor running and only got a strong suction, never felt any outward pressure at all. And also if you can please tell me what and how that 3/8 copper tube from the bottom tank hooks to. I know most compressors use a 1 way valve to keep pressure off the motor when starting with air in the tank. I dont know if there is maybe a one way valve in the tank where that 3/8 copper tube is connected or if maybe the one way valve was connected on the end of thet copper tube that is not connected to anything and then maybe it went from the valve into the out put of the pump. I connected the output of the air pump to the to the end of the 3/8 copper tube that wasnt connected to anything (and went into the tank on the other end) and ran the motor . There are 2 air outlets in the elec. pressure switch and I put my finger on them to see if I could feel vacume but I didnt feel any. I dont know if maybe that was because there is a one way valve in the fitting where the 3/8 copper tubing is connected or not.
So what I need to know is is the air valve on the pump head no good and causing the pump to **** air instead of blowing it out the air out of the head?
Also any help on the what and how to hook up the copper tubing to a regulator and to the air pump would be much appreceiated...
Thanks...............Dave

    The manual is very helpful thank you. But it dosent answer my main problem and question.
    Why is the pump sucking air from the air out and blowing it out the intake valve? What could cause that?

    Thank you. I guess Im not makeing my question very clear, sry. The problem is not the motor running bacwards. Even if it did I dont think that would cause the air pump to **** air in from the air output would it? The pump operates with a valve that is like a flapper valve I believe . Maybe I am wrong , I dont know for sure thats why I am asking. Maybe the air valve is shot?

    Natrin, that popular mechanics artical shows a clear picture of the operation of the air intake and output for the air pump. As I was looking at it it occured to me that if somebody had replaced that head on the air pump and put it on upside down that would cause the pump to bring air in the output and blow air out the intake just like its doing wouldnt it?

Hi and welcome to FixYa,

Offhand, when you removed the head, was there a base/plate with holes? If yes, then the sequence of parts would be head, gasket, slightly thick base/plate with hole, gasket, cylinder. To my knowledge, this thick plate with holes would be the valve assembly. One side would lead to the intake port/filter while the other would be towards the discharge port. If on the discharge port (leading to the tank) there is suction, then the valve plate was installed in reverse.

As to the "copper tube...bottom tank", I can only venture that it is a water discharge.

Good luck and Thank you for using FixYa. Happy Holidays.

Before I start trying to answer you problem, let me declare that I am not much into motors but in the course of my job, I have worked on pumps, compressors and motors.
Motors usually rotate opposite direction due to phase mismatch, which you can easily solve by changing the power supply connection. Also check the capacitor of the pump motor. Since you have bought and 2nd hand machine, it may have weaken.
You can use rubber/PVC pipes to join the mismatched connection with the help of a jubilee clip.
I think that will help you. Best of luck.
Please rate me appropriately if you are satisfied with my answer,in case, if you want any clarification please get back to me.
