Have you noticed a change in your water pressure and you don’t know why? Here are a few of the most common culprits.

 

Obstructions in the Piping

Sometimes a dip in water pressure is caused by an obstruction caught in your pipe. Check your valves for limescale build up which can cause restrictions or have a plumber inspect your pipes for internal blockages.

 

Improper Pipe Sizes

If you have consistent low water pressure, it may be that your system is fit with improperly sized pipes. Small lines with multiple fixtures can cause a noticeable pressure drop. If you think this may be the case, have a plumber inspect your pipes to find out for sure.

A Problem with Your Fixture

If you’re noticing lower water pressure in the shower but not elsewhere, your showerhead might be the culprit. If you have hard water, limescale often builds up in fixtures like showerheads and blocks them up. Give your fixture a thorough cleaning and see if the water pressure returns to normal. If it does, it might be time to install a water softener.

 

High Water Usage

If there is a lot of water usage on the same water line, you will see a downturn in pressure. If you notice the water pressure lower at certain times of day, like in the morning when people are likely to be showering, this is likely the issue.

 

A Hidden Leak

Low water pressure is often caused by a sneaky leak that you haven’t noticed. It is common for these leaks to be coming from your pipes within your walls, so the decrease in water pressure is often the first indication of the leak. If you suspect a leak in your pipes, call a plumber right away.
