Hot at the sink, not in the shower
When the sinks run hot and only the shower is stuck on lukewarm, the valve is holding the heat back, either through its limit stop or a worn cartridge. A tank problem would show up everywhere.

What’s different in Chantilly
Four in ten Chantilly owners heat with electricity, so a shower gone cold isn’t always the valve.
A handle that rocks often has a screw that’s backed out, so tighten that first. If it keeps spinning, the grip between handle and cartridge is worn, and the handle or the cartridge is what gets replaced.
The other complaint has a quick sorting test. Run the bathroom sink on hot. If the sink gets hot and the shower won’t, the problem is the valve: its hot-side stop is set low, or the cartridge is worn. If every tap runs lukewarm, the water heater is the thing to look at.
Chantilly leans electric more than most of its neighbors. Four in ten owners heat their homes that way, and an electric tank with one dead element can give a shower that starts warm and fades in minutes. It looks like a bad valve and isn’t, and a new cartridge would just be money spent.
Six in ten owner homes here went up in the 1980s and 90s, and about a quarter of homes are townhouses, where the bath upstairs often sits over a kitchen. Hardness runs 3.0 to 10.8 grains per gallon in Fairfax Water’s 2025 data, and Loudoun Water, across the county line, points its customers to those same figures.

- Most homes here are townhouses or condos, where the shower often sits over somebody’s ceiling, so a drip behind the trim gets fixed before it shows up as a stain below.
- Many houses here were built since 2000 with single-handle pressure-balancing valves, where a loose handle or a drip is almost always a cartridge.
The signs
When a shower in Chantilly needs a plumber.
The handle is loose or spins
Usually a set screw under the cap that backed out, or worn teeth where the handle grips the cartridge. Tightening the screw only lasts if the teeth are still good.
It drips after it’s off
On a single-handle shower that’s the cartridge. On an older two-handle or three-handle shower, it’s the washers or the stems. Either one comes out the front, and the wall stays closed.

Choosing who does it
How to pick who fixes a shower in Chantilly.
Questions to ask anybody who pulls your shower handle off, us included.
Did they run the sink on hot before they touched the shower valve?
It takes thirty seconds and saves a wrong repair. A plumber who goes straight to the valve without it may be guessing.
Did they pull the handle before quoting a new valve?
Most loose handles and drips are a cartridge or a screw. A plumber who prices a new valve without looking inside first may be selling you a wall you didn’t need opened.
Did they test it with a toilet flushed?
A shower that runs fine on its own can still jump hot when someone flushes. Ask them to run it both ways before they pack up.

Arrived within an hour on a Sunday morning and provided great service.
Called SwiftPro around 5 am and their electronic system scheduled an appointment for us same day.
Alex arrived on time and after some time he explained the situation regarding the low flow faucet and fixed the problem. Very professional. I would call on him and the company again for my plumbing repairs.

Questions
Shower repair questions from Chantilly.
My shower goes lukewarm after five minutes. Is it the valve or the water heater?
Sinks fade too? Then it’s the tank, often a lower element or a sediment-packed bottom. Only the shower fades? That’s the valve, at $250 to $450. We check both on one visit, which is $49, or $250 after hours.
My mail says Chantilly but I’m on the Loudoun side. Do you fix showers there?
Yes. A shower valve is inside the house and doesn’t care about the county line. The line only matters for the water meter, which is Loudoun Water’s on that side and Fairfax Water’s on the other.
How much is shower repair in Chantilly?
Most shower valve repairs we do run $250 to $450, with the visit at $49, $250 after hours. A whole new valve with trim runs $950 to $1,400, and a tub spout runs $200 to $400.
Will you have to open the wall or break tile?
Not for a cartridge, a handle or a diverter. Those come out the front. A valve replacement goes in from an access panel when there is one, and when there isn’t, a larger trim plate can usually cover the opening so the tile stays.
