Ran into problem trying to fix pull down spray head from a AquaSource (Lowe's) bar sink faucet that was leaking. Turns out those small size heads aren't obtainable.
While trying to stem the leak a bigger problem surfaced. Apparently I had not properly secured the spray head feeder line. It had fallen back out of the faucet assembly into the sink cabinet.
The feed hole barely allows the braided supply line to enter the spout assembly. It will not feed to the end where the spray head could be attached. Limited access wipes out being able to use a fish tape. Am thinking of spraying the spout housing with silicone to reduce friction when feeding the supply line.
Could use some handy hints.
