I installed this pump to pump water about 3 months agofrom my 5000 litre rain-water tank around the garden. I have to pump to a height of about 3 metres maximum through my system and a maximum of 30 metres length of 12mm pipe. So far I am very happy with its performance and it was very easy to install. My last pump lasted about 10 years and cost me twice as much as this so if it lasts anywhere near as long as this I will be very happy.
