Your bathroom is one of the most used spaces in your home—and that means plumbing problems are bound to happen. But how do you tell what’s just a minor hiccup and what could turn into a costly repair? Understanding the difference can save you time, money, and stress.
Let’s break down common bathroom plumbing issues and when to pick up the phone.
Slow Drains: Monitor or Call for Help?
A slow drain every now and then could just mean a buildup of soap scum, hair, or toothpaste gunk. Many homeowners clear these with a basic plunger or drain cleaner. However, if water consistently pools or smells foul, it may be time to call for drain cleaning. Persistent drainage issues can point to deeper blockages or even pipe damage.
Call a plumber if you notice:
- Standing water that doesn’t drain quickly
- Bad odors coming from the drain
- Gurgling noises when water goes down
Dripping Faucets: It’s Not Just a Small Leak
A constant drip may seem harmless, but it can waste gallons of water over time. Most drips are caused by worn washers or faulty cartridges. While some people can DIY a fix, others may benefit from professional assistance—especially if the dripping worsens or spreads to other fixtures. If you’re noticing multiple bathroom plumbing issues like this, it’s worth calling a licensed pro.
Signs that a faucet leak needs professional help:
- Dripping continues after attempts to tighten
- Water leaking at the base or under the sink
- Multiple fixtures dripping in the same area.
Noisy Toilets or Running Water: Annoyance or Alarm?
Toilets that “ghost flush” or constantly run can often be traced to worn flappers or valve problems—common wear that can be replaced easily. But if you hear bubbling or gurgling when you flush or run other taps, that’s a red flag. It might indicate a blockage in the sewer line, and you’ll want to reach out to plumbing services right away.
Watch for these toilet trouble signs:
- Bubbling sounds when using other plumbing
- Toilet tank refilling without flushing
- Persistent hissing, dripping, or running water

Low Water Pressure: Check More Than Just the Showerhead
Sometimes, low water pressure in your shower is caused by a clogged aerator or hard water buildup—both fairly easy fixes. But if pressure drops across multiple fixtures or happens suddenly, you could be dealing with a leak or corrosion in your pipes. These are bathroom plumbing issues that demand quick attention from plumbers to prevent damage.
Pressure problems that aren’t normal wear:
- Sudden drop in pressure across the whole bathroom
- Only hot or cold water affected
- No pressure even after cleaning showerheads or faucets
