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.

These guys know their business! Smart, knowledgeable, and willing to help. Even know I was only putting together a small collection system they couldn’t do enough to help. Rob is a stellar person to deal with and can’t wait to have him help with a 7,000 gal. system. If your looking for the best collection system on the planet look no further than Climate.

I ordered my first ever rain collection to make the barrels I had collected able to save rain water. I found the adaptors, the hose piping and the hose spigots very able to with stand the water pressure and not leak. I wish that there had been more emphasis on the importance of an exact perfect cut for the hose spigot or the adaptor will leak or pull thru. Written directions with pictures would have been nice. I plugged my sloppy cut hole and carefully cut another hole, inserted the universal adaptor and plastic spigot, and no worries!! Tons of water for my flowers. Great inexpensive product line.

I recieved my Grundfos pump in very timely manner. Unfortunately when I opened the box which appeared perfectly fine the pump inlet connection threads were slightly crushed. I did manage to re-thread the connector and attached the pump in the system. However when filled with water there was a crack that leaked water. I called rain harvest and the person I spoke with knew immediately what I was talking about and was able to pull up my order and order a replacement part. I was on the phone for maybe 5-10 minutes and the new part showed up 3 days later. Pump now works great. Best customer service experience I've ever had in my 55 years. Absolutely will do business with them again!
