I have a low flow aerator, .5 GPM, which is needed for an eemax hot water heater to work properly. The outside threads of the aerator are male, 15/16″ and have always worked with any faucet. We just replaced a bad faucet and the new one will only take an aerator which is male, 55/64″. I’ve never seen such a thing and can’t find an adapter to use with my 15/16″ aerator.
I also have looked for a new .5 GPM 55/64″ male aerator, but those don’t seem to exist either. Help please?
