Very affortable push-to-connection valve HOWEVER

Compared to some of the name brand 1/4" push-to-connect type plastic valves these are very affordable and reasonably priced. They seem to be well built and don't leak after installation HOWEVER I did notice one immediate issue after they were installed. I observed a decline in my RO water flow rate when these valves were installed compared to some of the other name brands such as Sharkbite or John Guest. Being the inquisitive type, I starting looking into the reasons why because from the exterior they look nearly identical. However when you view the internal orifice of the valve, there's a white plastic cross member (see the photos for details) directly in the center of valve's flow path. Not sure the reason it's there but that would account, at least partially for the reduction of water flow from the RO system due to the obstruction by the cross member. Very disappointed because I was hoping for an affordable alternative to the very expensive name brand 1/4" plastic valves. They may work for your application if your RO water pressure is adequate to compensate for the impedance from the cross member but it didn't pan out for me. Amazon's CS was great and I was allowed to return them for a refund within 30 days. Thanks Amazon!!
