A sewer camera inspection is $89 added to a visit we’re already making. It’s the cheapest way to know what a drain is doing before anybody talks about digging.

With Comfort+ membership, any service is 15% off, and a water heater flush with a sewer camera inspection and a plumbing safety inspection comes every year.

What’s different in Warrenton

In Warrenton the curbside cleanout, the meter box and the town line decide whose pipe it is.

Inside the town limits the Town of Warrenton is the water and sewer company, and it splits each service near the street: at the water meter, and at the sewer cleanout by the curb. From there back to the house is yours, as the rules below spell out. For a sewer backup, a frozen pipe or air in the lines, the Town’s own contact is its Superintendent of Transmission and Distribution, at (540) 347-1858.

That cleanout is the natural place to put the sewer camera in, and the pictures settle which side of it a backup sits on. A new water or sewer lateral from the street needs a Town permit and a cleanout built to its Public Facilities Manual. Swapping a toilet, a sink or a disposal, with the supply and drain pipes left as they are, takes no permit at all.

The Town has filed its lead service line inventory with the Virginia Department of Health, found no lead service lines, and keeps checking connections in person until every one is confirmed. Inside the walls is a different question. Close to four in ten homes in town went up before 1980, and the Town notes that lead solder has been outlawed in Virginia since 1985, so copper joints older than that may have been made with it.

In New Baltimore and Vint Hill the water comes from wells the Fauquier County Water and Sanitation Authority runs, and the Authority’s line is the meter box: everything on your side of it is yours. If the pipe between the meter and your property line breaks under the street, FCWSA repairs it, but only if nobody has tampered with it or replaced it first, so call the Authority before anyone digs there. Over 80 psi, its rules say to add a pressure reducing valve, $500 to $1,000 from us. Too little pressure, and they allow a booster pump and tank at your expense, with backflow protection the Authority approves.

Inside the town limits, a little over 4 of the roughly 110 square miles the two Warrenton ZIP codes cover: the Historic District around Main Street, Leeds Square, and the streets off Broadview Avenue and Alwington Boulevard.

What you’d notice

What a plumbing problem in Warrenton usually looks like.

The water bill climbs and nothing’s running

On Town water, a bill that keeps creeping up usually means a leak you can’t see, under the yard or in a toilet that never quite stops. The Town’s utility office will help work out whether it’s inside the house or out. If it’s on your side of the meter, leak detection runs $200 to $500, and keep the repair bill: the Town wants a copy with any request to adjust the charges.

Pressure that drops a little every year

Galvanized steel supply pipe rusts from the inside, so the pressure falls slowly until a shower upstairs is a trickle. The fix is new pipe, not a new faucet.

Water where it shouldn’t be

A damp patch on a ceiling, a warm spot on the floor, a meter that keeps ticking with every tap off. A slow leak inside a wall does most of its damage before it ever shows itself.

A drain that keeps coming back

One slow sink is a sink. Two slow drains on different floors are sharing the pipe out to the street, and a basement drain that gurgles while you run water upstairs is the main line talking.

After a heavy rain

After a storm in Warrenton, check the basement drains.

Heavy rain finds the weak spots in a house’s plumbing. Four checks you can make yourself, then call us and we’ll look at the rest.

  1. 1

    Water coming up a floor drain?

    Clear water with no smell is usually groundwater. Gray water, or a sewer smell, means the main line is backing up: stop running water in the house and call us.

  2. 2

    Drains slow or gurgling since the rain?

    A main line with a cracked joint or roots in it can take in groundwater during a storm and slow down. A sewer camera inspection, $89 added to a visit, shows where.

  3. 3

    Is the sump pump running?

    If the house has one, watch it once: it should start as the pit fills, empty it and shut off. Our sump pump replacement page has the rest of the checks.

  4. 4

    Did water reach the water heater?

    If floodwater got to a gas water heater’s burner or controls, leave it off. Don’t relight it until a plumber has checked it.

Call us after a storm and we’ll check it all: the floor drains, the main line, the sump pump and the water heater. Any repair gets its price in writing before the work starts.

Your pipes, your paperwork

Who owns what under the street in Warrenton.

Town of Warrenton

On Town sewer the owner keeps up the line from the cleanout at the curb, or the property line where there’s no cleanout, to the house, and on Town water the line from the meter to the house. The Town locates its own side; finding the house side is your plumber’s job. Source.

On Town water, the Town sends questions about water pressure to its Water Treatment Plant. Source.

Fauquier County

On FCWSA sewer, the service line from the main to the property line and the lateral from there to the house are the customer’s to clear. FCWSA clears its mains and fixes a service line under a public street, and it doesn’t reimburse a plumber. Source.

On FCWSA water (Bealeton, Catlett, Marshall, New Baltimore, Vint Hill and its other systems), FCWSA says it can’t guarantee uniform pressure, and that over 80 psi the customer should install a pressure regulating valve at their own expense. Homes on private wells aren’t covered by this. Source.

Choosing a plumber

How to pick the best plumber in Warrenton.

Questions worth asking anybody who comes out, us included.

  1. Will they start at the cleanout?

    On Town sewer the curbside cleanout is where the Town’s pipe ends and yours begins. A plumber who works here should find it, run the camera from there, and tell you which side the trouble is on before anyone prices a dig.

  2. Is the plumber licensed in Virginia?

    Anyone can check on the state’s license lookup in about a minute. It’s the one question that takes the guesswork out of the rest.

  3. Will they put a camera in before they talk about digging?

    A sewer camera inspection is cheap next to any dig, and it shows whether the problem is a root, a sag or a break. A quote to dig without one is a guess.

  4. Do you get the price before the work?

    Every plumbing job on our list has a range. A plumber who won’t say where yours lands until the wall’s open is asking for a blank check.

Tyson was super friendly, and extremely knowledgeable! He fixed my burst pipe faster than I ever could have on my own. I highly recommend SwiftPro services, and will absolutely call them when something inevitably needs repair in the future!

Questions

Plumbing questions from Warrenton.

Who do I call when the drains back up in Vint Hill?

FCWSA first, at (540) 349-2092. It sends someone to check its main and clears a blocked main whatever caused it. If the main is clear, the clog is in your service line or your building lateral, which its rules make yours, and it won’t repay a plumber, so that’s when you call us. A problem with the service line under the street itself is the Authority’s to correct.

Do you work on wells and septic systems out in the county?

No. Past the county’s service districts a house has its own well and septic system, and the well, the pump, the tank and the drain field belong with well and septic companies. Everything between them is ours: the supply pipe from the pressure tank in, the water heater, the fixtures, and the drain line out to the tank.

Should I call a plumber after a flood in Warrenton?

If water came up through a floor drain or stood on the basement floor, yes. Warrenton gets that kind of rain: NOAA’s Storm Events Database has Cedar Run over the Frytown Road bridge just east of town in August 2018, and the Town’s own flood checklist tells residents to clear their drains and gutters and to install check valves. A floor drain that backed up while it poured can mean trouble in your sewer lateral, and the camera from the curbside cleanout shows where. Call us once the rain stops and we’ll go over all of it, with any repair priced in writing first.

How much does a plumber cost in Warrenton?

It depends on the job, and every one has a published range: drain cleaning for one fixture $200 to $800, main sewer line cleaning $550 to $1,650, leak detection $200 to $500, a pressure reducing valve replacement $500 to $1,000, toilet repair $250 to $900. A sewer camera inspection added to a visit is $89.
