Why the age of your Arlington Heights house matters for plumbing
The village's own history page says the settlement officially became Arlington Heights in 1874 and that the Metra station anchors a walkable downtown. A community that old has homes built in many different decades, and we do not claim which streets are which. What matters for you is the build year on your own house.
Homes built in the postwar decades can often still have original galvanized or copper supply lines, cast iron drains and a water heater that has been replaced once or twice. Those materials can corrode or narrow with age, which shows up as low pressure, rusty water or repeat leaks. Newer homes more often have plastic supply lines and different failure points.
Ask your plumber to identify the pipe materials on the first visit. A short look at the basement tells you whether you are fixing one fault or watching a system wear out.
Repair or replace: an aging water heater in Arlington Heights
A tank that fails at 2 a.m. forces this choice quickly. The comparison below keeps it practical.
Repair makes sense when
- The fault is a single part such as a thermostat or element
- The tank itself is dry and sound
- The rating label shows a recent date code
- The heater still meets your household's first-hour demand
Replace makes sense when
- Water is leaking from the tank body
- Repairs keep recurring
- The date code on the label shows it is well along in age
- You want a different size or fuel type
The U.S. Department of Energy says to size a new heater by its first hour rating, which is on the EnergyGuide label, and supports a 120 F setpoint. Check water heater repair first, then water heater replacement if the tank itself has failed.
No hot water, or a tank leaking now?
Call (847) 281-8626 any hour and a plumber is dispatched for repair or same-day replacement.
Signs the pipes in an older home are wearing out
These are the symptoms that usually come before a major leak.
Pressure that has dropped over the years
EPA WaterSense gives 45 to 60 psi as the target at the house, with a regulator needed above 80. A gauge on a hose bibb tells you where you stand.
Low pressure on every fixture often points to a narrowed supply line or a failing valve. See water service line repair if the problem starts outside the house.
Rusty water that clears slowly
Discolored water after a shutoff can come from corroded galvanized pipe or a tired water heater. It is worth checking before it stains fixtures.
When several lines are affected, a plumber may discuss repiping instead of repeated patching.
Meter moving with everything off
A silent leak under a slab or behind a wall shows up as a meter that keeps turning. A plumber uses listening gear and a camera to find the spot without opening floors.
That is the work of leak detection.
Hard rain also tests basements. The National Weather Service recorded about 3.9 inches over two days in July 2017 near Arlington Heights, so a sump pump that works is worth checking.
Water supply
Lake Michigan water and what the village report leaves out
The village's 2025 water quality report says its sole source is Lake Michigan water treated by Evanston, bought through the Northwest Water Commission. That is the same supply as Buffalo Grove. The report gives no hardness value and names the Superintendent of Utilities at 847-368-5800 for that figure.
Evanston reported an average of 134 mg/L as CaCO3 for 2025 in its own report. On the USGS scale that falls in the hard range, but it is the supplier's number, not a reading from your tap. Test your own water before choosing a softener, and see water softener installation if scale is building up.

Pipe problems and the first thing to check
Use this to decide what to try before you call.
| Symptom | Quick check | When to call |
|---|---|---|
| Low pressure everywhere | Gauge on a hose bibb, target 45 to 60 psi | If below that range or above 80 |
| Running toilet | Dye in the tank, wait 10 minutes | If color reaches the bowl and a new flapper does not help |
| Brown water | Run cold taps for a few minutes | If it persists or only hot water is discolored |
| Warm spot on a floor | Check the meter with everything off | Right away, since it can mean a slab leak |
| Water heater drips | Look for the source: tank, valve or pipe | If water is coming from the tank body |
A plumber can read the same signs and give a price before work starts.
Permits, lead service lines and the rules behind the work
Arlington Heights runs permits through its Building and Life Safety Department at 33 S. Arlington Heights Rd, and the village says first submittals for building permits go through its electronic Civic Access Portal. The page does not say when a plumbing permit is required, so confirm before a water heater swap or a service line job.
Illinois law also requires water system owners to inventory service lines and replace known lead ones. A final replacement plan is due to the Illinois EPA by April 15, 2027. Ask the village where your address stands before paying for any work on the service line.
What affects the price of a water heater or pipe job
No dollar figure is quoted on a page, because the same job differs between houses. The price is given before work starts.
Standards behind this page
The village history, water report, utilities contact and permit office come from the Village of Arlington Heights website and its 2025 Consumer Confidence Report. Pressure and toilet tests come from EPA WaterSense, and heater sizing from the U.S. Department of Energy.
The lead line rule comes from Illinois Public Act 102-0613. Plumbers in Illinois are licensed by the Illinois Department of Public Health, which provides online license verification, and work follows the Illinois Plumbing Code, 77 Ill. Adm. Code 890.
