Introduction
Strong, consistent water pressure is something most homeowners take for granted. So when your faucet suddenly slows to a trickle or your shower loses pressure without warning, it can be frustrating and concerning. While low pressure sometimes affects a single fixture, a sudden drop throughout your home usually signals a deeper plumbing issue.
At Trade Pro Plumbing, we regularly help homeowners across Northwest Arkansas identify the cause of sudden water pressure loss and restore proper flow quickly. In this blog, we’ll explain the most common reasons water pressure drops, what you can check yourself, and when it’s time to call a professional plumber.
Common Causes of Sudden Water Pressure Loss
- Hidden Plumbing Leaks
One of the most serious causes of sudden low water pressure is a hidden leak. When water escapes from your plumbing system before reaching your fixtures, pressure drops as a result.
Leaks can occur behind walls, under floors, or even beneath your home’s foundation. Slab leaks are especially common in older homes and often go unnoticed until pressure drops or water bills spike.
Warning signs of a hidden leak include:
- Sudden increase in your water bill
- Damp spots on floors or walls
- Mold or mildew odors
- Sounds of running water when fixtures are off
If you suspect a leak, call Trade Pro Plumbing right away to prevent structural damage.
- Clogged or Corroded Pipes
Over time, mineral deposits, rust, and debris can build up inside your pipes. This buildup narrows the pipe diameter, restricting water flow and reducing pressure.
Homes in Northwest Arkansas with hard water are especially prone to sediment buildup. Older plumbing systems made from galvanized steel are also more likely to corrode internally.
If low pressure worsens gradually or affects older fixtures more than newer ones, pipe buildup may be the cause.
- Faulty Pressure Regulator
Most homes have a pressure-reducing valve (PRV) that controls how much pressure enters the plumbing system. When this valve fails, water pressure can drop suddenly or fluctuate without warning.
A failing PRV may cause:
- Sudden low pressure throughout the home
- Inconsistent pressure from day to day
- Noisy pipes or banging sounds
A licensed plumber can test your water pressure and replace the regulator if needed.
- Main Water Line Issues
Your main water line supplies water from the municipal system to your home. If this line is damaged, clogged, or leaking, your entire plumbing system will be affected.
Common causes of main line problems include:
- Tree root intrusion
- Shifting soil
- Aging or corroded pipes
- Construction damage
If every fixture in your home has low pressure, the issue may be with the main water line. Trade Pro Plumbing offers camera inspections and repair services to diagnose and fix main line issues quickly.
- Municipal Water Supply Problems
Sometimes the issue isn’t inside your home at all. City maintenance, water main breaks, or supply disruptions can temporarily reduce water pressure.
Before assuming the problem is internal, check with neighbors to see if they’re experiencing the same issue. If the problem persists beyond a short period, it’s time to call a plumber to rule out home plumbing issues.
What You Can Check Before Calling a Plumber
While many causes of low water pressure require professional tools, there are a few things you can check yourself:
- Make sure your main shut-off valve is fully open
- Check for obvious leaks under sinks or near appliances
- Remove and clean faucet aerators
- Test water pressure at multiple fixtures
If pressure is low everywhere or drops suddenly with no clear explanation, professional inspection is recommended.
Why You Should Not Ignore Sudden Pressure Loss
Low water pressure may seem like a minor inconvenience, but it can be a warning sign of serious plumbing problems.
Ignoring it can lead to:
- Undetected leaks causing water damage
- Mold growth inside walls or under floors
- Pipe bursts from pressure imbalance
- Higher water bills from wasted water
Addressing the issue early protects your home and prevents expensive repairs down the road.
