Question: Is this an "on demand" pump?
Document: This is an incredible pump, one of two I have had in service over a year now without skipping a beat. It can sit fir long priors and then work on demand first time every time. I have several models this on is flawless so far.
I have used this pump for about ten years to flow water from my rain collection system to my garden drip system. It's amazing. It will run on demand and run dry if my tanks run out of water. It pushes up the water pressure enough for the drip system to operate. I have two of them and they have each run for about ten years, then they get full of gravel, mud and crud from the bottom of my tanks and start leaking, but that's not the pump's fault.
Best price anywhere, fast shipping and great little pump to get our campsite water running!
The pump showed up early, was exactly what I ordered and worked flawlessly. I would recommend this product and amazon to a friend for sure
We had to replace our old pump and this one seems to be doing the job. Our last water pump had more GPM but this is plenty fast for us.... and we love taking our showers!
i have been using the pump recirculating water in a temperature range from 60 - 150 F a few hours a day for the last month without issuesseems to works as advertised
used this to supply my cabin with shower, toilet and sinks with a steady water supplyMaintains a constant pressure with a inline check system . It was a compact solution to a pump that would have been six times larger
I have used the pump one time and it did a good job. I did put a filter on the intake side to keep out contamination. However this should be done with all liquid pumps.Thank youFrank Winberry
Great Pump using on a trailer out in the country on a 250 gallon water tank to provide water to trailer.Please note that it is not providing water to a hot water heater just sinks and toilet.
Am using this pump as the primary pump for three outside rain barrels hooked up in series. It works great. The pump is covered from the elements and just keeps on pumping when asked. Would recommend this pump.
Answer: yes
