My Water Pressure is Low

Does your water pressure need a boost? Well pump pressure switch settings or low incoming water pressure from a municipal water supply are the most common causes of low water pressure in your home.

Why Your Home's Water Pressure Is Low

Whether it's low water pressure in your shower or your sink, hidden blockages can cause your water pressure to plummet suddenly or more slowly over time. So if your whole home is struggling to keep up with the pressure, it may be time to call in a professional.

Potential Issues

  • low water pressure throughout the house
  • low water pressure in the sink
  • low water pressure in the shower

A water supply line runs water into your house. If there's a restriction in the line, then you might notice low water pressure from a faucet. That's rather inconvenient when you try to take a shower or wash your hands.

The pipes in your home don't like cold weather any more than you do. If they're not kept above freezing, the water inside will turn to ice. As the water freezes, it expands, which can cause your pipes to burst or split open. Once the line has broken, the only thing preventing water from escaping is the ice itself. When that melts, it will start to leak. Depending on where the line broke, this could turn into a serious problem. In long-lasting extreme cold temperatures, the cold can creep into areas you wouldn't normally think it would. To help keep this from happening, turn up the temperature indoors. Even a couple of degrees can help keep your pipes safe and warm, and prevent freezing.

Your water softener sits between the main water line and your taps. During the day, water only passes through the water softener while you're running your taps. But, each night, your water softener takes advantage of the low-use hours to do a little housekeeping. Between 2:00 a.m. and 4:00 a.m, it runs water through the backwash line to clean itself before the next day. If the seals on the water softener are split, torn, or shifted out of place, or if the piston is scored or scratched, water will leak through the backwash line. Since the backwash line catches the leaking water and sends it out to the drains, it can be a hard problem to catch before you're smacked with a huge bill.

The main water valve is the control that turns the water on or off to your entire home. There are only a few reasons this valve is turned off on purpose. If you've recently done repairs, the main control valve is often shut to prevent leaking while the water heater was repaired or replaced. The main water valve can also be shut to winterize a home for sale. If neither of these is true, it's likely someone may have bumped the valve into the "off" position. No matter how it happened, as long as there's no risk of leaks, you simply need to switch it back on and be on your way like nothing happened.

If there is water on the floor under the main water supply, it could be caused by condensation or a leak. Water supply lines can sometimes leak if the pH of your water is too low. A pH of 7 is neutral, and anything lower than that starts to become acidic, which can wear down copper tubing and brass fittings. Once a leak has sprung, you'll need to replace that section of the line.
