Review on Culligan HF360A - Optimized Standard House Filtration System by Melissa Hart

(A) ez leaking. Drained 3 times: first through the threads - when making PVC you must use PVC compatible pipe grease and NOT Teflon tape (drained). Second, after releasing the pressure (red button), a piece of PVC was trapped between the washer and the bodywork from cutting. I had to loosen the stainless steel screw to attach it. Third: 10 hours after installation, it drips onto the thread again. I think the threads are badly cut because I only hand tightened them with no tools or tubing attached. (B) After this low quality experience, I looked at other brands. They are the same price, the filters are the same size and include a filter key. (C) Hermetic seals on filter housing. After you close the valves, you must relieve the pressure before they open.
