I'm flipping back and forth about which pump to buy and whether or not to use a tank. IMO, I think I would be better with a pressure tank and slightly oversized pump. We are replacing a submersible pump with one that will mount on the pier in our lake. The submersible was installed with a pressure relief valve rather than a pressure tank so it runs continuously while watering the lawn. We are pumping out of a lake to about a 60 ft elevation. The furtherest away head is rougly 250-300 ft. There are at least 4 rotators on each zone. We have 120 volt wiring available. I'm thinking a 1 hp convertible jet pump would do the trick but I don't know enough about pumps to be comfortable with my decision nor whether a well pump or irrigation pump would make any difference. Here's the spec's on a pump I am tempted to buy. Would appreciate any advice including the size of pressure tank if appropriate for this application.
