Low water pressure? Here’s what to do right now.
One weak faucet is usually the faucet. The whole house at once can be the city main, so check that first.

First, this.
One faucet: clean the strainer
If one faucet is weak, rinse the deposits off its strainer. Calcium carbonate from the water can build up in faucet strainers.

If water turns brown or red after nearby line repairs, run the faucet until it clears. If it doesn't clear within several minutes, call Longview's water and sewer emergency line at 903-236-3030.
SourceWhole house: it may be the main
If pressure drops across the whole house, a city main problem may be the cause. Report main leaks in Longview at 903-236-3030, or call Tyler after hours at (903) 597-6541.

Usually one to plan.
- Call now(city line first): no water at all, or a sudden whole-house loss of pressure with visible water in the street or yard.
- TodayA sudden whole-house drop with no city work or main break reported.
- Can waitOne fixture slowly weakening, or long-standing low pressure in an older home.
Before you call.
Safety first
- High pressure is a hazard too: most plumbing codes require a pressure-reducing valve when supply pressure exceeds 80 psi, because higher pressure can rupture pipes and damage fixtures. Source
- Do not turn the city's valve at the meter or curb. Longview allows only city employees or licensed plumbers to operate water valves; Tyler's service agreement forbids tampering with meters and valves. Source
What to tell the plumber
- Whole house or one fixture; hot, cold, or both.
- Sudden or gradual, and whether neighbors are affected.
- Whether you have a pressure-reducing valve and where it is.
- Age of the home and pipe material if known (galvanized steel, copper, plastic).
