About one year ago, I replaced my shower head and bath tub faucet. Prior to that, the pressure was good. After those installs I noticed that my pressure went down. The presuure continued to go down until recently when I flush my toilet, it takes three times for my pump to come on and fill it up. Before that it took one time. What could be my problem? Could it be (1) too much air in line? To correct that do I just open the relief valve until water comes out and then close it? (2) a malfunctioning valve regulator? or (3) could it be my pump? Please let me know. Thanks.
