Water Pressure Diagnosis & PRV Repair
Weak showers and banging pipes usually trace back to a handful of causes — a failing pressure-reducing valve (PRV), a partially closed valve, hidden leaks, or aging pipe. Eco measures your actual pressure with a gauge, isolates the real cause in a set diagnostic order, and fixes exactly that — a PRV replacement is a routine repair, not a mystery.

Water Pressure & PRV Repair FAQs
What is a PRV and how do I know if mine failed?
A pressure-reducing valve sits where the main enters your home and holds household pressure in a safe range, typically around 50–60 psi. A failing PRV causes sudden whole-house pressure that's too low or too high, or pressure that fluctuates. A gauge test confirms it, and replacement is a routine repair.
Is high water pressure actually a problem?
Yes — pressure that's too high stresses fixtures, supply lines, and your water heater, and it can cause leaks. If your gauge reads well above the safe range, correcting it is cheap insurance for everything downstream.
Will I need a repipe to fix low pressure?
Often not. If the cause is a failed PRV, a partly closed valve, a clogged aerator, or a single leak, the fix is targeted and affordable. Repiping only enters the picture when corroded galvanized supply lines are the bottleneck — diagnosis first tells you which situation you're in.
Why is only one fixture weak?
A single weak fixture is almost always local — a clogged aerator, a sediment-packed cartridge, or a partially closed angle stop. Whole-house weakness points upstream to the PRV, main valve, or supply pipe. Sorting one from the other is the first thing we check.
Could low pressure mean a hidden leak?
It can. Slab leaks and buried service-line leaks bleed off pressure and waste water quietly. If valves and the PRV test healthy, leak screening is the next honest step — we pinpoint before anything gets opened up.
