A plumbing inspection in Fort Washington means a plumber checks the water heater, supply and drain lines, fixtures, shutoffs, gas piping and any irrigation backflow device, with a sewer camera run if needed. Most homes here are on WSSC Water. Call the number on this page to be connected with a local plumber in Fort Washington.

Fort Washington was mostly rural until about 1960 and is now a suburb of riverfront homes, neighborhoods like Tantallon and Fort Washington Forest, and marinas near Fort Washington Park. The median home was built around 1980, so the houses are old enough for original water heaters and valves to be worn, and larger lots often have irrigation that brings in WSSC backflow rules.
What to do now
- Pin down your contract's inspection deadline and schedule the plumber in the first days of it.
- Ask the seller whether the house has an in-ground irrigation system and when its backflow assembly was last tested.
- Look up the address on WSSC Water's service line map at wsscwater.com/LCR-map.
- Write down any symptoms you noticed on your showing: low pressure, slow drains, a sewer smell, water stains.
- Make the water heater, main shutoff, cleanout and irrigation valve box easy to reach.
Symptoms and likely causes
| Symptom | Likely cause |
|---|---|
| Hot water runs out quickly | Sediment in the tank or a failing element or burner |
| Sprinklers run but no test tag or record | Backflow assembly overdue for its annual test |
| Toilets gurgle when the washer drains | Partial blockage or venting problem in the main drain |
| Damp spot in the yard near the street | Leak on the owner's side of the water service line |
| Main shutoff stiff or seeping | Old valve that has not been exercised |
WSSC requires testable backflow assemblies, such as irrigation pressure vacuum breakers and reduced pressure zone devices, to be tested every year and after installation, repair or relocation, by a plumber holding a WSSC license who is a certified cross-connection technician. Homeowners may only rebuild or replace non-testable devices, and WSSC says non-testable dual checks and boiler devices should be rebuilt or replaced every five years.
Cost factors
- Home size and number of baths and gas appliances
- Whether irrigation and backflow are included
- Adding a sewer camera run
- Repairs that follow need a WSSC Water permit; gas water heater and furnace work must be done by a gasfitter holding a WSSC license
Gas here is Washington Gas. If you smell gas, leave first, then call 911 and 844-WASHGAS (844-927-4427), option 1.
