Low water pressure is one of the most common calls we get across Martin and St. Lucie County. One day the shower feels fine. The next, every faucet sputters, the washing machine takes forever to fill, and you’re wondering if the problem is the city line, the well, or something inside the house.
Advanced Plumbing has served Stuart, Port St. Lucie, Palm City, Jensen Beach, Hobe Sound, and surrounding Treasure Coast communities since 1998. If your pressure dropped suddenly — or has been getting worse for months — here’s what usually causes it and when you should call a licensed plumber instead of waiting it out.
What Low Water Pressure Usually Feels Like
Homeowners describe it differently, but these are the patterns we hear most:
- Weak flow from every faucet (whole-house problem)
- Weak flow from one fixture only (localized clog or valve issue)
- Good cold water, weak hot water (often water heater or hot-side piping)
- Pressure that drops when more than one fixture runs at once
- Pressure that comes and goes during peak neighborhood demand
Whole-house problems and sudden changes deserve a professional look. A single slow sink is annoying. A sudden pressure drop across the house can signal a leak, a failing well pump, a partially closed main valve, or sediment buildup that will not fix itself.
Common Causes on the Treasure Coast
1. Partially Closed or Failing Main Shutoff
After a repair, remodel, or even a careless bump in a garage or utility closet, the main shutoff can sit half-closed. That alone can starve every fixture. We also see older gate valves that no longer open fully.
2. Clogged Pipes or Aerators
Florida’s water can leave mineral buildup. Aerators and showerheads clog first. If cleaning those does not help — and pressure is weak at multiple fixtures — scale or debris may be restricting supply lines, especially in older homes with galvanized pipe.
3. Leaks You Cannot See Yet
A slab leak or underground line leak can lower pressure before you ever see a puddle. Watch for unexplained high water bills, warm spots on floors, or the sound of running water when everything is off. Those are call-now signs, not wait-and-see.
4. Well Pump or Pressure Tank Problems
Many Martin County and surrounding homes are on wells. If you have a well and pressure is low, cycling oddly, or the pump runs constantly, do not ignore it. A failing well pump or pressure tank can leave you with weak flow — or no water — fast in Florida heat.
5. Water Heater Restricting Hot-Side Pressure
If only the hot side is weak, sediment in the tank, a failing dip tube, or a closed shutoff on the water heater can be the culprit. That is a different job than a cold-water whole-house issue.
6. Municipal Supply or Peak Demand
Occasionally the issue is upstream. If neighbors report the same drop at the same time of day, note when it happens and call your water provider. If neighbors are fine and your house is not, the problem is almost always on your side of the meter.
Quick Checks Before You Call
These take a few minutes and can save a service trip when the fix is simple:
- Confirm the main shutoff is fully open
- Unscrew and clean faucet aerators and the showerhead screen
- Check whether the problem is hot only, cold only, or both
- Ask a neighbor if their pressure changed today
- Note whether the drop was sudden or gradual
If pressure stays low after those checks — or if you suspect a leak — stop experimenting and call.
When Low Pressure Is an Emergency
Call a plumber the same day if you have:
- Sudden pressure loss with the sound of running water
- Water stains, soggy drywall, or a warm floor slab
- A well pump that will not hold pressure
- No usable water for cooking, bathing, or sanitation
- A broken visible supply line
