Shurflo water pump problem

Hey you guys are smart. I knew I joined the right forum. Guess what both the faucet aerators were plugged with junk (calcium carbonate). I know what happened, when I filled my fresh tank with water, I must have had the hose on too high and stirred up some stuff that then got into the faucet aerators and plugged both of them. I cleaned them out and got full pressure. Problem solved, but now unfortunately the water pump will not shut off with the faucets off because some of the same stuff probably got into the valves. We have very hard water here so it probably is calcium carbonate. I guess I'll also be learning how to take apart a water pump to clean the valves. I also will be flushing out and draining the fresh water tank from the spigot on the tank. Thanks all! Don
