Hello,
As part of a green business certification, I'm trying to reduce the flow of our kitchen faucet (1/2" FIP) to 1.5 GPM (without replacing the whole faucet). I purchased a flow restrictor intended for a shower (Shower Adapters, 1.5 GPM Maximum Flow Rate, Female 1/2"-14 NPT x Male 1/2"-14 NPT) after researching that 1/2" NPT is the same as 1/2" FIP). And from what I understand 14 threads per 1/2" is the standard thread density as well.
So I tried to install it on the cold water line, unscrewing the standard supply line with the 1/2" FIP fitting. I tried to thread the supply line to the flow restrictor and it works with no problems. I then unscrew it and try to thread the adapter to the kitchen faucet intake and it won't go more than a 2 rotations before sticking and resulting in the copper line to the faucet rotating/deforming. When I restore the water pressure I get water spraying from the link between the flow restrictor and the kitchen faucet intake.
Thinking there was something wrong with the part, I tried putting it on a shower head and both sides screw in with no problem.
What am I missing? Why can't I get the adapter onto my kitchen faucet intake? I know that it was intended for a shower, but shouldn't the NPT standard be... ...standard? Thanks for anyone who has a hunch on this.
