Didn't even last a day
using it to intermittently drain a small water trap. Turns on via relay triggered by float switch. Didn't even last 4 hours of 20sec run times, 10min or more off.
Best value low powered pump
If you are looking for a powered pump to fill up your tank(s) or for a water system that isn't being used constantly this unit is ideal. The flow rate is 4.3LPM which perfect for most application, for more high powered water pumps you would need to implement something to control the flow rate otherwise you end up running through your water supplies. Seaflo offer a 3 year warranty across their range of pumps which definitely rings peace of mind.
Super quiet, yet powerful pump
I recently purchased this pump from my local RTM store, the staff were kind enough to recommend this as a replacement to my old pump. I am extremely impressed how quietly the pump runs, without any affect to it's pressure and flow. I highly recommend purchasing Seaflo's range of pumps, not to mention the lengthy warranty they also have. Fantastic value for money.
Great little pump
These pumps are excellent, reliable and use very little power. I have been running one of these for a while now in my camper and i especially love the on demand feature so i dont have to worry about switches etc.
Small but sufficient
Have it in a van for sink with pull out hose for the occasional shower and works great.
