FAQs
What are the most common causes of low water pressure in Harrison homes?
In Harrison, low water pressure is usually linked to one of four issues: (1) aging galvanized or corroded copper piping that has narrowed internally; (2) mineral-rich local water that leaves scale deposits in aerators and valves; (3) partially closed shut-off or pressure-reducing valves after recent utility work; and (4) small, undetected leaks that lower overall system pressure. A professional inspection can quickly confirm which factor—or combination of factors—is responsible in your home.
How can I tell if the low pressure is coming from the city supply or my own plumbing?
Start by asking neighbors if they are experiencing the same problem; if they are, the issue is likely with the municipal main. Next, locate the main shut-off valve where the service line enters your house: test pressure at that point with a gauge. If it reads 50–60 psi but faucets farther inside are weak, the restriction is inside your plumbing. If the gauge reads under 40 psi at the main entry, call the Harrison Water Department to report a supply issue before scheduling in-house repairs.
Can clogged pipes or fixtures really reduce pressure that much?
Yes. Harrison’s water has moderate hardness, so lime scale, rust, and sediment can accumulate over years, shrinking a ½-inch pipe to less than ¼ inch. Similarly, aerators, shower heads, and cartridge valves collect debris that chokes flow. A licensed plumber can clear or replace fixtures, power-flush supply lines, or in severe cases repipe affected sections to restore full pressure.
What role does a pressure-reducing valve (PRV) play, and could it be the culprit?
Many Harrison properties have a PRV on the main line to tame high street pressure. If the PRV spring weakens or debris lodges in the valve, it may fail partially closed, dropping household pressure to under 40 psi. A plumber can test inlet versus outlet pressure: if the upstream side is healthy but the downstream side is low, the PRV needs cleaning, adjustment, or replacement—usually a 30-minute job with excellent results.
Is low water pressure ever a sign of a hidden leak?
Absolutely. A pinhole leak in a supply line or a slab leak can bleed off pressure even if you don’t see water pooling. Watch for unexplained spikes in your Harrison utility bill, hear hissing in walls, or notice damp spots on flooring. A pressure test or acoustic leak detection performed by a professional can confirm whether a hidden leak is stealing your water pressure—and wasting water.
What steps will a professional plumber take to diagnose and fix low water pressure problems?
Our Harrison plumbing team follows a proven checklist: 1) Measure static and dynamic pressure at multiple points. 2) Inspect the main shut-off, PRV, and water meter for partial closure or malfunction. 3) Remove and clean faucet aerators and shower heads for instant improvement. 4) Use boroscope cameras or ultrasonic equipment to locate internal pipe scaling or leaks. 5) Perform localized pipe flushing or, if necessary, replace undersized or corroded sections with modern PEX or copper. 6) Verify pressure after repairs and recommend point-of-entry filtration or softening to prevent future buildup. This systematic approach restores strong, consistent pressure while addressing the root cause.
