Low water pressure is incredibly annoying—from weak showers to washing machines that take forever to fill. But it's also a warning sign. Low pressure usually means there's an underlying issue in your plumbing system. Here are the most common reasons your water pressure has dropped, and how we can fix it.
Partially Closed Shutoff Valves
The most common reason for low water pressure is a partially closed shutoff valve. Check your main water valve and the one near your water heater. If someone bumped them or didn't open them fully after a repair, it will restrict water flow to your entire house. Make sure they are completely open.
Pressure Regulator Issues
Many homes have a pressure regulator (PRV) on their main water line to keep pressure at safe levels. When this part fails, your water pressure can drop dramatically or spike too high. We can easily test your PRV and swap it out for a new one if it’s broken.
Mineral Buildup and Scale in Pipes
Escondido has incredibly hard water. Over time, those minerals build up inside your pipes, shrinking the opening and choking off your water pressure. We often see this in older galvanized pipes and showerheads. Cleaning fixtures helps, but severe pipe scaling might require a targeted repipe.
Leaks in the Supply Line
If you have a hidden leak in a main supply pipe, water is escaping before it ever reaches your faucet, causing low pressure. If you've noticed a drop in pressure along with a higher water bill, you need professional leak detection right away to find and fix the break.
Municipal Supply Issues
Sometimes, the issue isn't even in your house! Municipal water main breaks or high neighborhood demand can drop your pressure temporarily. If your neighbors are dealing with the exact same issue, call your water utility. If it's just your house, the problem is definitely in your plumbing.
Corroded or Aging Pipes
If you live in an older home with original galvanized steel pipes, rust and corrosion have likely built up inside them, severely restricting your water flow. If cleaning your aerators doesn't help, we can inspect your system and let you know if replacing those old pipes will solve the problem.
