Review on Filtration Mounting Hardware Included Transparent Filtration by Dion Madison

I thought the brass inserts put them a step above the rest. Not correct. The input/output ports on the heads of these devices are drilled at a slight angle. So if you put three of these in series (like I did), instead of being straight and bulging, they would curve upwards, making copper tubing a nightmare (and ugly at that). That wouldn't be so bad unless they lick like crazy. I had them send me another set (I thought the ones I received were defective) but the second set they sent had the same problem. These heads have a manufacturing defect affecting 6 of the 6 heads sent to me. You can't line them up and set them flush on a three-row bracket. If you want to pay a plumber twice (once to install this junk and a second time to remove and install something that doesn't leak horribly and is done right), buy this product. If you still want to take the risk, be sure to install a bypass so that when you see for yourself what I'm talking about you don't create a moat waiting for them to leak. weak to send you another set which will have the same problem. I've never said this before, but if I could give this product 0 stars, I would. And I'm writing this review 5 months after the fact.
