Trusted Plumbing Services in Fort Washington, MD
Fort Washington is right next door to us. Custom Flow Plumbers is based in Oxon Hill, just up Indian Head Highway — and Fort Washington’s big single-family neighborhoods, from Tantallon to Fort Foote to Friendly, are some of the closest work we do.
These aren’t cookie-cutter houses. The median Fort Washington home was built in 1979, most of the town went up in the 1960s through the 1980s, and nearly all of it is detached single-family homes on larger lots. That means longer sewer lines running under mature trees, basements that sit close to the water table near Piscataway Creek, and plumbing that’s been working for 40-plus years. We know what that combination breaks — and we fix it properly.

Professional Advice
Our plumbers will tell you honestly what's wrong, what it takes to fix it, and what can wait — so you spend your time and money where they actually matter.
Safe and Sure
A professional repair protects your pipes, your drains, and your property. Your home is in careful hands from shutoff to final test.
Appropriate Use of Tools and Methods
Specialized tools and proven methods resolve most plumbing problems efficiently — camera equipment when a line needs eyes on it, the right machine for the right drain, no guesswork.
Backed by a Two-Year Warranty
Repairs and installations are covered for two years on the parts and labor we supply. If a part we installed fails within two years, we redo it. (Drain cleaning isn't warranty work — clearing a clog is a service, not a repair.) Full details are on our Services page.
We know Fort Washington houses — and what goes wrong in them
- Long sewer laterals under mature trees. Bigger lots mean longer lines from house to street, and Fort Washington’s older neighborhoods are full of shade trees. Roots find the joints in aging lines — recurring slow drains or backups are usually roots, not a simple clog.
- Sump pumps that earn their keep. Homes near Piscataway Creek and the Potomac side of town sit close to the water table. When a sump pump quits during a heavy rain, the basement finds out fast. We repair, replace, and test them before storm season does it for you.
- 1970s-era plumbing at end of life. Original water heaters are long gone — most homes are on their third or fourth. Copper and galvanized lines from that era are pinholing, and shutoff valves that haven’t moved in decades tend to fail the one time you need them.
- Big-house water demand. Eight-room colonials with three-plus baths put real load on older water mains and heaters — low pressure at the far bathroom is a system talking, not a fixture failing.

Fort Washington plumbing FAQ
How fast can you get to Fort Washington?
We’re based in Oxon Hill, minutes up MD-210 — Fort Washington is home territory, not a long trip. Call (301) 971-4884, Mon–Fri 8am–5pm, and we’ll get you scheduled.
My drains keep slowing down. Is it roots?
In Fort Washington’s older neighborhoods, often yes. Long sewer lines and mature trees are a classic combination. A camera look in the line tells us for sure before anyone talks about digging.
Who provides the water here?
Fort Washington is served by WSSC Water. If pressure drops or water discolors across the whole house, it may be the utility’s main rather than your pipes — we can help you tell the difference.
Should I test my sump pump before spring rains?
Yes — pour water into the pit and watch it cycle. If it hesitates, hums without pumping, or doesn’t start, call us before the storm does the testing for you.
