The 4300 series is a fantastic 12V pump. Very reliable with great pressure. This purchase replaced an identical pump which lasted about 5 years before a permanent magnet dislodged. The only disadvantage is its vibration so you have to isolate it properly for domestic applications. Rod from Pump Warehouse is great to deal with
I bought this pump for irrigation purposes and was a bit concerned if the pump would be adequate to lift the water as high as I need to... no worries at all, even with a high head the pump maintains its high pressure and doesn't even seem to draw much from the battery which is set up only with a solar panel to charge it. Great product and even better service...
