Emergency Low Pressure Or No Water: What To Check
A sudden drop to almost no water can mean a broken pipe, a failed valve, or a utility interruption. Check whether neighbors have water. If they do not, call your water provider first.
If only your home is affected, check that the main valve is fully open and listen for running water. Call our 24/7 emergency line if you hear water running, see water where it should not be, or the pressure fell suddenly.
One Fixture Or The Whole House
The first question we ask is simple. Is the low pressure at one faucet, or everywhere? One weak faucet usually points to a clogged aerator, a partly closed shutoff valve, or a worn cartridge. Those are small repairs.
Weak pressure in the whole house is a different problem. It can come from the main shutoff, a failing pressure regulator, a leak in the service line, or pipe that has narrowed inside.
Pressure Regulators And Main Valves
Many homes have a pressure regulator near where the water line enters the house. Its job is to hold pressure steady. When it wears out, pressure can drop or swing up and down.
A main shutoff that is only partly open can also restrict flow. This happens after plumbing work or a repair. We check the valve and the regulator first because they are quick to test.
Corroded And Narrowed Pipe
Older galvanized pipe corrodes from the inside and narrows over the years. The result is weak pressure that gets worse over time and is worst when two fixtures run at once. Our whole-home repiping page explains when replacing the pipe is the better fix.
A hidden leak can also look like a pressure problem. If water is escaping before it reaches your fixtures, leak detection may find it.
Low Pressure Only On The Hot Side
If cold water is fine and the hot side is weak, the cause is often the water heater or the lines near it. Sediment in the tank, a partly closed valve, or a failing heater can all reduce hot water flow.
Our water heater repair page covers what we check. If your home has a filter or a softener, flow through that equipment can also be restricted, and water filtration explains how we service it.
Low Pressure Calls Across Our Area
We handle pressure problems in Woodstock, Towne Lake, Hickory Flat, Sixes, Holly Springs, Canton, Acworth and Kennesaw. Homes on well systems around the edges of our area can have different pressure equipment. We ask which kind of water supply you have before we plan the visit.
Our dispatch line runs around the clock for calls where the water has stopped entirely. We work to the manufacturer's installation guidelines and to the plumbing standards that apply at your address.
What To Tell Us When You Call
A few details help us bring the right parts and plan the visit. Tell us whether the problem is at one fixture or the whole house, and whether it affects hot water, cold water, or both.
Let us know if it started suddenly or got worse over months, whether neighbors are affected, and whether any plumbing work was done recently. Also tell us if your home is on city water or a well. These answers often point us to the cause before we arrive.
Frequently Asked Questions
Why did my water pressure suddenly drop?
A sudden drop can come from a burst pipe, a failed valve, a utility interruption, or a partly closed main valve. Check whether neighbors are affected, then call us if they are not.
Why is the pressure low only at one faucet?
A clogged aerator, a partly closed shutoff valve, or a worn cartridge is the usual cause. These are small repairs we can often complete the same visit.
Can a hidden leak cause low water pressure?
Yes. Water that escapes before it reaches the fixtures can lower pressure throughout the home. We can locate it with leak detection.
Do I need a new pressure regulator?
Only if testing shows the old one has failed. We check the pressure first so you know whether a replacement will help.
