had a new 275 gal oil tank installed. Oil company fills up but i ran out of oil in less than a week. Delivery man can not hear whistle and so he doesn't give enough oil fearing he will cause a flood. Had a tech come out and he blows air into fill line and there is no hearing the whistle outside the house yet it is heard standing next to oil tank in basement. What are some possible causes for this happening ?
