Craig P. is absolutely correct, and the answer didn't cost a penny! I, however, took my MH to the shop, when that happened and was charged a fee, for the same info. Now, my sprayer has a plastic tie-strip on it, so that it is on all the time and the faucet knobs have to be turned off, at the faucet, to stop the spray. Never have anymore problems.
