My faucet spout came out of the faucet assembly, and I had a small gusher of water. Upon examining the spout, there are two o-rings at the base, but nothing that will keep the spout in place. When I tighten the collar to attach the spout to the faucet, the spout is still easily removed.What keeps the spout from coming out of the faucet? I'm thinking some kind of clamp, but there is no evidence of any.Thanks!!!
