Low Water Pressure in Your House? 7 Causes & How to Fix Them

By Top Florida Plumbers · Updated 2026-11-08

Low water pressure is frustrating in the shower and worrying everywhere else, because it's often a symptom of a bigger problem hiding in your pipes.

Common causes of low water pressure

• Partially closed main shut-off or meter valve – check these first.
• Clogged aerators or showerheads – Florida's hard water leaves scale that chokes flow at a single fixture.
• Failing pressure-reducing valve (PRV) – if your whole house dropped suddenly, the PRV is a prime suspect.
• Hidden leak – water escaping under the slab or in a wall lowers pressure everywhere.
• Corroded galvanized pipes – decades of rust narrow the pipe until flow is a trickle. Repiping is the permanent fix.
• Water heater issues – low pressure only on the hot side points to sediment or a failing heater.
• Municipal supply problems – ask neighbors; if everyone is affected, call the utility.

How we diagnose it

A pressure gauge at the hose bib tells us whether the problem is incoming supply or inside the house. A meter test reveals hidden leaks. If the pipes are the issue, we'll show you the corrosion and explain repipe options in PEX or copper.
