    Hi

    I have a 4 channel watering system which until recently I was running of the municipality water with no problems. We've recently gone ahead and had a Well Point installed (about 12 meters deep pump above ground type). The well point pump unfortunatly doesn't have enough pressure to drive the watering system. I also have a 500litre tank.

    I assume to fix the pressure problem I am going to have to either pump the water into the 500litre tank and then use another stronger pump for the watering system or I have heard of pressure tanks but am not understand how these work.

    Please can someone help me so that I can use the well water in the irrigation system.

    Thanks very much

    Newbie

    Pressure tanks don't make pressure, pumps make pressure. If you tell us what kind of pump you have, we can tell you how much water and pressure it will build. If you try to use more water than the pump can supply, you won't have any pressure. You are also limited by how much water the well will make. You can't pump 12 GPM if the well will only make 10 GPM. You have to match how much water the well will produce, with a pump that will provide the correct amount of water, at the pressure you need. Then you have to match the amount of water being used, with the amount and pressure the pump can supply.

    Horse power is a good start. Make and model would be next. And you are talking litres and meters, so is this a 50 hertz motor?

    Pool pumps make terrible sprinkler pumps.
