Review on Universal 3-Way Shower Arm Diverter Valve For Handheld And Fixed Spray Head, G 1/2 Bathroom Shower System Replacement Part In Brass With Brushed Nickel Finish by Chris Rob

I bought this after buying the MODONA diverter. That valve worked but impeded flow by quite a bit and my attempt to widen the holes with a drill compromised the seal. which in that case worked by a valve stem in an open chamber being attached to a pad that occulted the outflow holes. MODONA also is one piece and simply rotates around the shower spout pipe when being tightened; MINGOR has a captive nut that doesn't put the orientation of the valve on the pipe. Like MODONA, every part of this I can see is brass.This valve works differently. I'm actually not sure how, because I haven't taken it apart, but there's no visible movement in the output holes when the valve moves. There was a negative review depicting a round discharge hole (the input hole is the hex-shape for a Allen wrench you see in the product photo) and as you see, the one I have has a binocular-shaped discharge hole. The other output hole that is connected to the showerhead is the same.Another question you may have like I did, is whether G 1/2" is the same as IPS 1/2". "G" is also known as BSPP. In this chart I found, IPS (listed as NPSH) is not exactly the same but very similar; close enough that it fits. On that matter, this tightened more solidly to the shower spout than the MODONA or for that matter the existing showerhead. It included tape (which you really shouldn't use for IPS threads anyway, the yellow pipe dope you can see in the photo was there to seal the MODONA and wasn't necessary for this).So now what you're really reading about: flow. How much is it? In this case, it did restrict flow- but less than MODONA which was a serious compromise on performance. Also, whatever the mechanism is, it seems to accommodate dual-flow very well. Overall an excellent value and product.
