    Water not going in tank

    I have installed a 50 gal bladder tank and water is not getting in the tank. The pressure gage shows 24psi, and I have lowered the tank pressure to 8psi. The tank is new and in the book that comes with the tank shows nothing to do except to hook up the 1-1/4" line. Am I doing something wrong? I also saw a plastic screen on the tank inlet prior to placing the 90deg. elbow. Any help would be helpful. Tony.

    ps The pesure gage is 12" from the tank and no valve in between.

    I remember years ago, installing Well X Trol Bladder Tanks, that the Bladder would stick to the bottom of the tank when first installed. While the Pump was building pressure the bladder would stay stuck until the pressure got up way higher than the Precharge. Then all of a sudden the bag would let loose and take in water. I haven't seen this happen in many years.

    You say you are getting 24 psi. Is that all the Pump can do?

    By the way, a Bladder Tank will only have a small amount of water in it, the rest is all compressed air.

    Wow Speedbump the sticking bladder sure sounds like the problem. I would have never thought of it. The pump is a 1hp 1-1/2" inlet/outlet and is 600 feet away from the outlets. I'm getting 24 psi at 500 feet and the line is 1-1/4". the pump has to draw up 8' from the river to the pump, and then another 20' up 500 feet away. Would it be better to install the tank next to the pump? Rite now it's at 500 feet away and the pressure gage at the tank is 20 to 24 psi. If I would have known before I started this project I would have purchased from your store. And should the inlet pipe from the river be 1-1/2" ? Rite now it's 1-1/4". You are very helpful to this site. I will try the sticky bladder test tonight, and post the results tomorrow. Thanks Bob, Tony.

    You need air pressure of 1-2 psi less than the cut in pressure setting on the switch. That's with no water in the tank. Example, for 30/50 psi water pressure, you need 29-28 psi air with no water in the tank.

    If the Pump has a 1.5" inlet and outlet, it's a centeriugal Pump. That is the wrong pump if you need pressure. I assume you have installed a Pressure Switch on this Pump. Centrifugals are not meant to be used with a Pressure Switch.

    Yes the Tank should be with the Pump and so should the Pressure Swtich.

    I don't know what your doing with this system, but if you want pressure, your going to need a tricked up Jet Pump or a Submersible Pump. Centrifugals are only good for a total of 40 - 50 psi.

    I tried looking up your pump at Graningers. They say there is no such number.

    OK, sorry for the lack of info. Here is what I have. I am watering about 1/4 of an acre that is about 600 feet form the pump. The garden area has 4 sprinklers that seem to work well, but at times the little lady just wants to run the water hose to water pots and small jobs. This is why I installed the tank and pressure switch. If I close all of the valves, eventually the pump shuts off, but in just 1 minutes it runs again and cycles like that. I presented this project to a sales guy at grainger who said this is the equipment I need. And I will move the tank to where the pump is if it will fill the tank and run the pressure switch.
    Is it wise to let the pump run while all of the faucets are closed? Does this cause the pump to run hot? If I need to purchase a new pump I may have to. Thanks guys. Tony.

    ps And believe it or not, the sales guy sold me a zero pressure Cut Off Switch. For the longest time we could not figure out why there was no power to the pump.

    Graingers seles people are not Pump professionals.

    You will need a Check Valve if you want the Pump to stay off. You will find that when the Lake level drops the Pump won't shut off anymore and it will nuke itself. Or it will start cycling on and off while your using just the hose and the Motor will fry. Trust me, it's the wrong Pump. I would take it back to Graingers and ask for a refund since he sold you all the wrong equipment anyway.

    Do you have enough water in this Lake to immerse a three foot Submersible Pumps?
