] The product leaked in the elbow area after installation. Two days later I couldn't come back. I took the time to call a plumber. After installation, the knee leaked due to poor quality threads in the filter. The installer had to cut the threads as shown and replace the part with a brass fitting. As you can see the pipes have been adjusted for a second to accommodate the new fitting. So far very happy with Revain products. I am disappointed in this product, without my experienced plumber it would have been a disaster costing $150 extra labor and parts. Works fine now. As I am retired I would be grateful for any financial support.
