Harvesting rain is a practice that has been around for centuries. Cisterns and other rain harvesting systems are widely used in Europe, Australia, India, the Bahamas and countless remote countries - many who depend solely on rain for day to day life.When water supply becomes limited, practical solutions can fill the gap. Rainwater harvesting systems provide distributed stormwater runoff containment while simultaneously storing water which can be used for irrigation, flushing toilets, washing clothes, washing cars, pressure washing,or it can be purified for use as everyday drinking water. You can really take this as far as you want. But it all comes down to various filtration and processing systems.Explore: Let us guide you through the entire process.Understand: With our rainharvest lab it becomes easy for you to envision a rainharvest system of your own.Collect: There is more rain coming, catch it.

I ordered 4 and installation was different for each location. There are no mounting ears of any kind, so I generally had to drill through the plastic to adequately secure the system. Thus far, they have filtered out cedar needles that have caused me problems with other filter systems.

The tank arrived "intact" but it looked like it had been through WW III when it got to my house. I should have just driven to Georgia to pick it up. It would have been 6 hours of driving but would have been worth it. The people at RainHarvenst systems were very accommodating. Thanks to RUSS for quoting shipping and finding me the best price on a 1500 gallon tank. Matthew S

All was good, just missed a star for lack of more protection in packaging, lamp sleeve was broken, haven't contacted seller for lack of time, Thanks

Great help with quote and answering questions on the phone during installation. However, the barb fitting for the pickup line was too large for the connection on the tank requiring a 60 mile round trip back to town to pick up a $1.59 barb connection.

Thank you for the review Ryan! Apologies for the confusion with the downspout diverter stainless steel filter. The plastic ring was originally used as a seat for the filter before the lip was added to the inside of the socket the filter currently sits on. Due to your question we will reach out to the manufacturer to avoid any confusion in the future! We also have a diagram of way the components all go together to complete the entire first flush system here at the bottom of the page: http://www.rainharvest.com/rain-harvesting-pty-downspout-first-flush-diverter.asp Please feel free to call us or use the live chat if you have any questions or comments in the future. Thanks again Ryan!
The only reason I am not giving the 5 stars is because I have had to order a replacement for one of the first flush kits I installed earlier in the year. I was unaware that I needed to open up the bottom to prevent the first flush PVC reservoir pipe from shattering during a hard freeze. There were no hints about winterizing the system. I didn't realize the tube would not drain fast enough to prevent shattering – it just didn't occur to me that it would take a few days to drain the melted snow coming off of my roof. Most of the yearly precipitation happens in the winter where I live; this is a particularly cold, wet year.

Thank you for your review, Kirsten. I apologize that you were not made aware of the winterization requirements. Due to your comments, we have added the following verbiage to our first flush product webpage; Important Winterization Instructions: Before the first hard freeze, simply remove the bottom "Screw Cap" to prevent the first flush PVC reservoir pipe from fracturing during a hard freeze. The PVC tube should be fully drained in order to prevent damage to the diverter chamber. Store the bottom cap and be sure to screw it back on for warmer weather and fully resume the first flush functionality. Viewable here: http://www.rainharvest.com/rain-harvesting-pty-downspout-first-flush-diverter.asp Please contact us if you need any rainharesting equipment or advice in the future. Thanks again!
