Question: It appears that the pump should be mounted outside the rain barrel in a convenient location.  What is the approximate head to which the pump can raise water?
Document: The RainPerfect Solar Powered Rain  Barrel Pump works great for filling one rain barrel to another 75 ft. away or water my greenhouse with a fine shower head a short distance away. I just love it!
I wanted to add another rain barrel (the flowers and vegetables very much prefer rain rather than chlorine laden water) but really did not have the extra time to fill up the watering cans. My wife found this item and got it for me as a present. Of all the products I have purchased over the years that do not live up to their expectations, this is not one of them. After charging the pump, it works exactly like the video. I have it hooked to a 50' hose and am able to use the spray head to water the garden and flowers.
Like an idiot, I left the battery outside all winter and now it won't charge. Unfortunately, I can't seem to get a replacement. Nobody appears to sell them. I don't really want to have to build my own, which looks like being my only option. Perhaps the manufacturer will read this and sell me one? That would be nice! I give this product only one star simply because of the difficulty of getting the replacement. My only other option appears to be to buy a whole new pump which isn't exactly a very "green" thing to do.
I have a setup with two connected rain barrels and a 30' hose, and was really happy to see this pump work on them. It is very easy to setup, very silent, and on a full charge lasted about 20 minutes (enough to empty about 1.5 barrels of water). The pressure feels like about half of what the city provides, but is definitely adequate for watering the plants (didn't try a sprinkler, though).A few things to note:1. You really have to make sure you install the solar panel in a very sunny location.
I was hoping for a way to empty my rain barrels more effeciently. I decided on the RainPerfect Pump. Its battery life is so-so. It takes 2-3 days to fully charge. Once charged, it works as advertised. It will empty 2-50 gallon barrels on one charge. Though I do not get 8 hours of sunlight at the solar panel location, I get a good 5 hours. I would expect this unit to charge quicker than 3 days.
The pump may be good for small rain barrels, but given its limited capacity, it exerts a lot of compromises. The cable to the charging panel is too short, which limits where one can place it. The net result is that one cannot often place it in an optimum location. I bought two of these units. One lasts for about 10minutes, but the other only lasts for about 2 minutes. The pumping capacity does not increase too much even if I leave it charging for many days. Their customer service is good, but good customer service cant really do much to resolve the fundamental design limitations of this product.
Pump is low pressure but works well if you are planning on using for small areas or one sprinkler head only. Not sure the battery charges up in 8hrs but it does charge.
We had barely a trickle coming from a full rain barrel. This pump really worked well and we even attached a hose to help water nearby plants. Worth the investment!
The pump worked for me straight out of the box. I use it with soaker hose and it does a great job - almost too good as I need a larger rain barrel to keep up with the water demands.
We have three rain barrels on different downspouts. One of them is next to our detached garage at the back of the yard. We didn't use that water much because of the distance to haul. We hooked up this pump to that barrel and although the pressure isn't strong enough to water all the grass in our yard at once, I can move the sprinkler around and water it in 3 sections.We are very happy with this pump and I will probably buy one for each rain barrel.
Answer: yes
