There should be hot and cold water "low point drain valves" somewhere. Mine are located behind an inspection cover in the outer wall of the bathroom. Make sure these are both closed completely or the fresh water system will not pressurize and pump won't pump properly and won't shut off, might pulse on and off. There may be a clear plastic filter in the water line between water tank and pump. The filter has a fine screen inside to stop sediment from entering the pump. The filter may come apart to clean the screen. Make sure all faucets are closed including the outside shower if you have one.
The water lines going from the pump to the toilet, sinks and water heater must not have any leaks and all faucets must shut off completely. As elderly as your rig is, the faucets and toilet valves may be defective/worn out. Make sure the 12 volt DC electrical connections to the pump are making good contact and supplying enough current to the pump. Your mechanic could have been sold a used/defective pump. Is your house battery fully charged. It should read about 13 volts while pump is running, test with a digital multimeter set on 20 volts DC range.
Welcome to the joys of owning an old motorhome. Try to learn as much as you can about the electrical system and how to test and maintain batteries. Expect to spend money getting and keeping everything operating properly
