    Sprinkler system

    I must replace a Peabody Barnes 1/2 hp jet pump . I am getting confused as to which type pump I need . The water line is at 65' (I have no idea how deep it is) . My check valve is above ground about 1 foot in front of the pump . I need 12-15 GPM . My question is do I have to have a deep well jet or can I use a shallow well jet which offers more volume .

    You've got me confused. If you mean static water level by "Water Line" you would indeed use a deep well jet pump. But if you have a check valve in front of the pump and you only have one pipe going to the well, you have a shallow well jet pump.

    Another thing. Asking 15 gpm from any 1/2hp jet pump is asking a lot.

    Do you have a picture of the install we can look at?

    I do have a picture but they are not allowing me to attach it to the forum . The static water level is exactly what I'm talking about. I only have 1 (1 1/4") pipe going into the ground . I have the check valve just in front of the pump . Am I understanding that I am using a shallow well jet pump on a 65' suction lift ? I am going to upgrade to a larger pump but I need to find out what I need. If you would like to see the pics,you can send me your e-mail via my e-mail(user name).I can send them to you that way . Thanks

    If your photo is bigger than 1.47 meg, the Forum won't accept it. You can send it to: transfer@pumpsandtanks.com

    Maybe I can shrink it a bit and make it fit here for everybody to look at.

    Keep in mind, a shallow well jet pump will lift water vertically 25 feet. Not 25.5 but 25 period, or less. So if you have water and only have one 1-1/4" pipe with a check valve, your water level has to be less than 25 feet.

    O.K. I sent the pics. Just to make sure I stay on the same page,a little more info.When you look at the pictures,coming right out of the jet is my check valve,then 90's down directly into the ground.Discharge goes directly into sprinkler manifold.No tank,no pressure switch,only a on-off switch. This is an old pump(at least 30 yrs)and I cant find any info on it even though I have the model and serial no's.If you could identify the type of pump it is, I will simply replace it with the same type and 1 to a 1-1/2 hp. motor. I will remeasure the static water level this afternoon when I get home.

    It is one of the non repairable type pumps. This was a dirty trick they did back in the 70's. They used what is called a partial frame motor. You can't put a replacement motor on this pump. The motor is thrubolted to the seal plate. There is no front end bell on the motor. Anyway, it is a shallow well jet pump.

    You can replace it with a 1hp jet and get lots of water and pressure. You can look at my Jet Pumps if you like. Just click the link.
