Reasons Why Your Water Pressure is Low

Running shower head

Having low water pressure can drag out the time it takes to complete the simplest of activities and chores. Using the washing machine, dishwasher, sinks, and shower can take twice as long when your water pressure is below the norm. Here’s why your water pressure is so low.


  • Ask your neighbors to see if the whole neighborhood has low water pressure. If so, install a water pressure booster valve.
  • When your neighbors have good water pressure and you don’t, check your main line for a water pressure reducing valve. Remove the valve or adjust it to a higher setting.
  • Make sure the main shut-off valve is completely open.
  • There could be a leak in the main line, so it’s best to have a plumber inspect your home’s plumbing system.

Poor Faucet Performance

  • When it’s just one faucet that’s giving you less than stellar water pressure, check its aerator. Unscrew the nozzle on the faucet and clean out or replace the aerator.
  • When the shower head is under-performing, soak it overnight in a water and white vinegar solution. This will remove any buildup of limescale and mineral deposits.
  • If the problem is not with the faucet, then you may have a clog in your plumbing line. Call a professional plumber to clear up this issue.

Hot & Low
Low water pressure when the hot water is being used means that there’s an issue with the hot water heater. Call in a plumber to fix this fixture, but before you do that, make sure the shut-off valve to the tank is completely open.

Having low water pressure is not only a nuisance, but it can also be a warning sign for a more serious problem that needs to be corrected.
