  • Product Description

    Replacement filter for Water Filtration Company roofwasher filters and/or floating intake filters. If you have an older cistern and live in Ohio, Kentucky, West Virginia, Indiana, Pennsylvania, or Texas, and are wondering what that fiberglass or concrete box is outside your house, chances are good that you have an old Water Filtration Company roofwasher and that you need these filter elements to keep that roofwasher working properly. This element also works with floating intake filters that they made to install inside the cistern (or pond).

    PLEASE NOTE: Filter does NOT come with fiberglass end caps. You are ordering just the filter element.


    Dimensions: 16" long x 12" diameter

    1. Floating Intake Screen/Filter works perfect

      I have a cistern that uses a floating intake valve. I have been unable to find a replacement until now. Replaced existing screen/filter very easily and the new screen fit perfect and works great. on 8th Oct 2020

    3. Excellent Product

      Delivery was great. The Roof Washer Filter was above our expectations as it's well made. So happy you supply the filters as you know the company in Marietta, Ohio has closed. Thank you! on 15th Aug 2019

    5. Rain Brothers saved my roof washer

      I don't usually write reviews, but I was compelled to this time, because the level of frustration trying to find this filter was overwhelming. I cant tell how much relief I had finally finding the right filter.

      I just bought a house with a cistern. I knew nothing about cisterns and did not even know what a roof washer was. After weeks of research, I found that I had the Water Filtration Company roof washer. Then I found out they were out of business. I called everywhere I could think of, but no one knew how to get a new filter.

      I finally found out Rain Brothers carried the filters. I ordered them and had them within just a few days and they worked great. It was a great relief to finally get a new filter because the previous owner was sick and unable to take care of the roof washer, so the filter had not be changed in years. There was a tree sapling growing out of it. After a major cleanup, a new filter, and a new screen, my roof washer is working at a 100%.

      Thanks Rain Brothers!

    6. perfect

      I’ve been using these outdoor filters from Rain Brothers for years. We use them for both our roof washer and floating cistern filters. I can always rely on Jonathan Meier and Rain Brothers for not only the products we need for our rainwater catchment system, but for the tips and expertise that comes from those who know their business. They’re always there when you need their help and products. on 7th May 2018

    7. Happy To Have Found Them : )

      Glad I was able to locate these filters, I use to purchase from Water Filtration Company in Marietta. I have to assume they are out of business was not able to reach them by phone? I also hope you continue to stock these filters. I don't want to have to succumb to the cost of a tap fee for Delco water ! on 2nd Aug 2017

    8. clean water

      We ordered 4 of these roof washer filters and they were exactly what we expected. The packaging was great. None of them showed any damage. Another plus... they arrived in a timely manner. on 3rd Apr 2017

    9. Simple, effective technology at a reasonable cost.

      I hope you continue to carry them. on 23rd Mar 2017
