There is a minimal $55 charge to check water pressure, which is added to your bill. Phone number is 937-333-3905. Is this a sudden drop in pressure or has it been low for a while? If it is a sudden drop, please check for water bubbling in your yard, or if someone left the garden hose on. Is the pressure low all over the house or just in certain areas? Do you have galvanized or copper plumbing? If you have galvanized, more than likely the pipes are clogged. We will come out and change the meter and make sure the curb stop is turned on. If that doesn't help, and the problem is clogged pipes, the service line will need replaced. The service line is the homeowner's responsibility. The service line runs from the curb stop to the meter, and is underground. If the pressure is low just in certain areas of the house, it then appears to be internal and you will need to call a plumber. Is it low just at the kitchen sink? Do you have an aerator? If so, unscrew it from the faucet, clean it out, and screw it back on.
