i see...it's called kingston brass. looked nicely made (better than at home stores), but more complicated. i haven't disassembled the entire thing yet... won't have time untll later in the week 'cause i need to use the sink now.i only rechecked the above connections. glad it's only the sprayer thats a problem. too bad i have a outside job...i like working on my house better. instant gratification. well in this case, maybe not so instant, but still fun. thanks for your direction...the instructions/info that came with the faucet are sparce, to say the least. i'll let you know how it works out.
