Thanks, all! Yesterday, I flipped the water pump circuit breaker off and back on again and I heard the pump working and the sink turned on. The water in the sink started to flow and then seemed to loose pressure. The pump turned back on and the water started pressure increased. Does this at all sound like an accumulator issue? I can see the manufacturer date on the pump as '12. The accumulator looks to be original as its date is '01. Sounds like I should clean the strainers at least.
And I did a visual on the water holding tank and can see it is more than half full.
