Low water pressure in your home is typically caused by a restriction somewhere in the pressure water system. The first thing we do when we encounter this issue is look to see if the pressure is on the hot or cold side (or both), and then we also look at whether the pressure issue is present in a particular fixture or throughout the house.
If you have low water pressure in one toilet, sink, or shower (and nowhere else), then your issue is actually with that one fixture. You can fix it by either cleaning out the aerator or replacing the actual components inside the faucet.
However, if you have low water pressure throughout the house, determine if it is for hot water, cold water, or both. If you have low water pressure on only the hot side, I would venture to say you have something clogging it in the water heater. Check your water heater, the flexes, the valves, and all the water connections to make sure there’s no restriction there.

Next, consider your water softener. Over time, these can go bad and create water restrictions. If you don’t have a water softener, the next thing to check is your homeowner shut-off valve, which is typically located near your water meter. In Central Texas, we often see the homeowner shut-off valve next to a pressure reducing valve, so if you have one of these, be sure to check both to make sure neither is causing the restriction.
