The short answer
Girl math says plumbing in Northern Virginia is a side hustle right now: $249 made on a water heater flush, $300 on a sump pump, $170 on a water test. The real math is that you pay $99, $697 and $29, and each of those is a fair price if you actually need the thing. Here’s how to tell.

The flush

| The girl math | The real math |
|---|---|
| $199 flush, $149 plumbing check, $99 total. I’m a financial genius. | That’s the offer, one per household, owner-occupied homes. One catch: after ten years without a flush, the sediment can be packed hard and opening the drain can start a drip. We look first and tell you. |
Not sure which you’ve got? The water heater age lookup reads the serial number. Tankless? The descale is $300, regularly $350.
The water test

| The girl math | The real math |
|---|---|
| $29 comes off a water treatment install, so if I buy one the test was free. | That part is true. A licensed plumber tests your hardness in grains per gallon and walks the plumbing with photos. It’s not a lab test for lead, bacteria or PFAS, so don’t count it as one. |
The sump pump

| The girl math | The real math |
|---|---|
| I saved $300 and the water alarm is free. That’s a vacation. | You spent $697 on a cast iron pump in your existing pit, a quiet check valve, new pipe to the discharge and a bucket test. A new pit, a battery backup or electrical work is extra. |
The slow drain

| The girl math | The real math |
|---|---|
| A $99 drain clearing is cheaper than the three bottles of drain opener I’ve already bought. Eventually. | It covers a blockage up to the P-trap. Deeper work is a separate service, and you get that price before we start. Our drain cleaning cost guide has the ranges. |
The backflow test

| The girl math | The real math |
|---|---|
| I got a letter from the water utility, and now I’m $50 ahead. | It’s $250 for a home’s device up to 1 inch. We test it, tag it and send the results where your utility wants them, so the letter stops. |
Where to start if you only do one
Water on the floor beats everything, so call that in first. Otherwise, start with the thing that’s already bugging you: the slow drain, the utility letter, the sump pump that’s older than your kids.
