My owners manual from Newell suggest running the water pump when connected to city water to maintain pressure. Even so, I think Michael hit the nail on the head. To verify if a collapsed white water hose is the problem, why not connect a water pressure gauge to the city faucet to confirm if the pressure is adequate. I replaced my Newell installed 110v pump with a Shurflo and I am satisfied with the pressure at 45 pounds. I leave it on even when connected to city water, and thus far not problem. Hope this helps.
