Can cold weather cause low water pressure?

Low water pressure is one of the most aggravating difficulties that may arise during the winter.

This blog article will explain how cold weather causes low water pressure and how to restore it throughout the winter.

Frozen pipes are the most common cause of water not flowing from the showerhead or faucet during the winter. If the pipes are partly clogged, the volume of water coming into your home may be reduced, resulting in low water pressure during the winter.

What Causes Low Water Pressure?

low water pressure causes

Low water pressure is a typical home plumbing problem that may impact faucets, dishwashers, sinks, toilets, showerheads, and any other plumbing fixture.

Water pressure can be easily affected by a blockage in a pipe. It could be caused by things like dirt, food particles, sand, solidified oil, and grease, or foreign objects.

If there are cracks in the water main, pollutants can back up and block pipes. 

Minerals build up in pipes over time, which makes them harder to move water through and lowers the water pressure.

Can Cold Weather Cause Low Water Pressure?

Low water pressure is one of the most aggravating difficulties that may arise during the winter.

When you switch on the sink or the shower, you will see that the water pressure is substantially lower than usual, and equipment may malfunction. 

This may be tough to cope with since most of us depend on clean, fresh flowing water for our daily lives. 

Water pressure is lowered by cold weather in the following ways:

1. It Leads to the Frozen Pipes

In cold temperatures, a low water pressure flow may suggest frozen pipes.

Water cannot flow through pipes that contain ice. They may also rupture and produce flooding on the property.

This might be the reason for the lack of water pressure if the temperature is below freezing and the water hasn’t been flowing for a while.

2. It Leads to Water Loss

Storms throwing debris around your home are more common when winter weather sets in.

Dirt, trash, and leaves may block your pump, causing the water level to drop.

If your pump is too deep in the well, water output may decrease, resulting in low water pressure and filling the pump with air.

A good contractor will unblock the pipes before leveling the ground.

3. It Wreaks Havoc on Water Heaters

Your water heater works hard enough all year, but it works much harder to heat your water in the winter.

Because of an increase in demand for hot water during the winter months and water being transported to the water heater at significantly lower temperatures. 

Your system goes into overdrive and suffers from wear and tear, resulting in low water pressure.

Without regular maintenance in the lead-up to winter, it is highly typical for water heaters to malfunction or entirely fail as the temperature lowers.

4. It May Lead to Drains

During the winter, most people pour oil or grease down their kitchen sink to repair frozen pipes.

Pouring oil or grease down cold or frozen pipes may cause these substances to freeze, causing major clogs and low water pressure.

Pouring hot water down your drains will sometimes remedy the problem, but more often than not, you’ll need to bring in a plumbing specialist.

5. It May Lead to Pump Failure

Speaking of pump failure, a harsh cold might impact the equipment.

Wells and pumps are often located deep enough down that even a severe frost will not impact them.

However, cold weather and high winds might cause your pump to fail, resulting in low water pressure. 

6. It Can Cause the Valve to Close

During cold weather, frozen pipes cause your home’s valve to shut off, which should be kept entirely open.

The pressure available to all outlets throughout the house will be affected by a partially closed valve that enables water into the residence.

How to Fix Low Water Pressure in Cold Weather

Low water pressure may be inconvenient throughout the winter, particularly when the demand for hot water is at an all-time high.

You want your sinks, showers, and plumbing systems to work as they should.

If you are experiencing low water pressure throughout the winter, here are several quick fixes:

Find Out What’s Causing the Water Pressure to Drop

Determine the source of the low water pressure before attempting to resolve it.

Frozen pipes are the most common cause of water not flowing from the showerhead or faucet during the winter. 

If the pipes are partly clogged, the volume of water coming into your home may be reduced, resulting in low water pressure during the winter.

Furthermore, low water pressure could be caused by increased water demand. 

This is especially true during the winter when people enjoy taking longer and warmer showers to keep warm.

Another reason could be the recent installation of a new bathroom or kitchen. Increased demands on the water supply may result in decreased pressure.

Fix The Problem With Low Water Flow

You may believe you have a problem with low water pressure, but the real issue may be low water volume. The two issues are distinct.

Low water flow indicates that much less water enters the pipes than is flowing.

Iron, hard water, or silt in your water source might be causing the poor flow. It might also be caused by obstructed pipes caused by mineral and sediment accumulation.

Before you can remedy a low water pressure issue, you must first rule out low water flow.

Check For Low Water Pressure in Every Part of the House

check water pressure everywhere

You should inspect each faucet and showerhead to see if all systems have low water pressure.

Allow the water to run concurrently to determine whether the problem is limited to one area or affects the entire household. 

Check every room in the house, including the kitchen, bathroom, basement, and outdoor faucets.

You may have a blocked aerator or faucet if the low pressure is just in one area.

In this scenario, remove the system and properly clean it. Check for debris or accumulation in the aerator.

If cleaning does not solve the issue, purchase a replacement. You should also run cold and hot water through all of the faucets.

If you only experience low water pressure while using hot water, there might be an issue with your water heater that has to be resolved.

Examine the Water Shut-off Valves

inspect shut off valves

If you can’t narrow the problem to one or two spots, you’re dealing with a general low water flow issue.

Inspect your home’s water shut-off valves and Pressure Reducing Valve (PRV). These are often the root causes of low water pressure, particularly in the winter.

The PRV, which resembles a bell, is positioned where the water supply line enters the house.

Check to see if the water pressure changes. Turn the screw clockwise to tighten it and boost the water pressure.

Similarly, to reduce water pressure, spin the screw anticlockwise.

If this does not work, the valve may be damaged and must be replaced.

Examine the Shut-off Valve on Your Water Heater

The heater’s shut-off valve may be faulty if the low water pressure issue only occurs while running hot water.

Turn off the water supply tap and empty the heater to repair it. Turn off the gas and drain the water, so it does not spill when you remove the shut-off valve.

Remove the gas line from the heater while doing these operations for increased safety. 

Inspect the Sensor to Ensure It is Operational

Replace the sensor if it is damaged. After that, unscrew the shut-off valve using a wrench.

Check the O-ring for fractures or brittleness that has developed over time. Make sure the sealant is clean and well placed.

Finally, reconnect the gas line and plug the sensor. Turn on the water supply to determine whether the issue has been resolved.

Find and Repair Water Leaks

Any leak on your property might cause low water pressure. Leaks may occur anywhere along the distribution lines, including the water main.

To repair small leaks, use a compound stick. Simply massage the compound stick over the gaps, and the leakage should stop.

A compound stick may seal minor leaks even while water flows through the pipe.

You may also use the epoxy paste to fix leaks on dry pipes, but ensure the water is turned off first.

Install a System of Constant Pressure

When another outlet is switched on, the water pressure at one outlet drops. Install a constant pressure system to solve this issue.

This gadget may be installed in the basement at the point where water enters your property.

Its purpose is to provide steady water pressure while many appliances and faucets operate simultaneously.

The constant pressure system will change depending on the water used in your home.

Notes To Take

take notes

Low water pressure results from frozen pipes, faulty water heaters, leaky water lines, ruptured pipes, and other plumbing issues brought on by the cold weather.

However, you can do a few things to reduce your chances of having a low water pressure problem during winter.

  • Allow water to drip from your faucets.
  • Bring the garden hose inside.
  • Pouring grease or oil down the drain should be avoided.
  • Make use of pipe sleeves.
  • Pipe insulation
  • Keep your garage door closed.
  • Wrap your water heater with insulation.
  • Reduce the setting on your water heater.
  • Your swimming pool should be drained.
  • Plan water heater maintenance.
