I had a wonderful experience working with the Product Water team. Jack was able to tailor a solution specific to my needs and financial constraints. He spent the time to educate me and ensure I was able to make adjustments on my own in the future. This means that I will be able to easily add additional capacity to my rain harvesting system in the future.

Jack has also remained available for additional questions and consultation after finishing the job which I appreciate.

I highly recommend working with Jack and to set up a water harvesting system if you are looking for establishing an environmentally conscious irrigation plan for your property.

Response from the owner 03:40 15 Apr 25

Thank you Addison. It's a pleasure collaborating with forward thinking homeowners like you, who see the future and work towards generating serious money saving installations, while adding value to their properties.

Jack is an enthusiastic and knowledgeable proponent of rainwater harvesting. He takes the time to explain the elements of his work and make suggestions. His years of experience in this work are obvious. I’m looking forward to learning how to better use the collection system that I have and exploring the options. Thanks for your support, Jack.

Product Water has been an incredible service from the first consultation and on, through multiple follow-ups to maximize the potential of our system. As environment-conscious first-time home owners in the Pacific Northwest, the system installed and maintained by Product Water delivered on its aim. Our front yard is now watered exclusively from the water we collect, and the water diversion system vastly reduces stain on the municipal waste-water system and therefore erosion on the Duwamish river, further supporting re-habitation efforts. They also helped us navigate the Rain Wise Rebate system so the city compensated us for the majority of the project. If you are eligible for the Rain Wise program or just wanting to expand your rain water collection and usage, we highly recommend working with Project Water.

Response from the owner 01:42 16 Oct 24

Will--thanks! Our project is very satisfying, as collaborating to achieve full potential is fun. Working with homeowners who's SPU Rainwise projects are the starting point to achieve large scale water storage, followed by homeowners adding management capabilities, like low pressure drip and more capacity is the aim of Product Water. Seeing your garden and other plans take shape is an honor. Thanks Jack

Product Water LLC is knowledgeable, answered all our questions thoroughly-with great explanation. We are very happy with our new Rain Wise system.

Response from the owner 19:22 27 Mar 24

Thank you for a Five Star review. Establishing a supplemental water source is a smart plan, easy to figure out and put in place. Your open minded thinking is a pleasure to work with. Product Water customers never second guess a decision establishing maximum rain water storage capacity.

I had a great experience working with Jack on my RainWise cistern project. After coming up with a plan we both agreed was the best option for my house, he let me know what to expect at each step of the process, which made it incredibly simple and convenient for me. I now have an effective rain management system in place, and, with the RainWise program, at a very minimal cost

Response from the owner 02:05 10 Sep 24

Andrew, with your guidance, together we solved water pouring back into your foundation (stormwater) established 1000 gallons of rain water storage (water conservation, utility reduction) and prepared you well for the future. Got a nice sized rebate too. Thanks for calling Product Water.
