- Robby R.
I feel that the tank was only drained, which I could have accomplished with a water hose attached to the tank outlet. What I thought I was paying for was a flushing of the tank.The tank is 17+ years old and I assumed that the elements would require replacement, especially the bottom element....
2 Brothers Plumbing - Robert F.
They did a solid job. Told me my water heater was too old to really benefit from the flush (I suspected that), but they fixed a connecting valve. Also helped fix issues with two toilets' tank refilling. Not a demanding job, but they addressed all related issues as best possible.
- Katy R.
I was very pleased with my experience with Boswell Septic. My job, which was a replacement of a 50-year-old collapsed system, was logistically complicated. The tank to be replaced was on a wooded slope and surrounded by old-growth Mountain Laurel and Azalea bushes. The Boswell father and son...
- William W.
My gas furnace boiler with room radiator heaters was not getting heat to the 3rd floor. I called Harry, and because it was cold and winter, his response was to make his call a priority. Within a day he was able to come out, and diagnose the problem as the need for a new pressure tank. ...
- Michael F.
We had a leaking toilet tank in our full bathroom. I purchased a tank-connecting kit and took care of that problem. After opening and closing the shut-off valve a number of times, a small leak in the valve was noticed. It was a week before Christmas, and we were really hoping to get this...
- Beth K.
My hot water tank was not working. My first call to schedule an appointment was not returned. My second call four days later was returned. After I explained my problem, Mr. Saini informed me that the business really focused on A/C units and would not be able to take on my job for at least two...
- Helene Q.
Initially Mike only gave me an estimate for an expansion tank, but I decided to replace everything because the heater was old and it wasn't cost effective to replace the expansion tank now and then discover I would need a new heater. (I'd already had some repairs over the past few years.) ...
Stevens Co - Janet S.
When I called SAIA and explained my situation, they told me up front what their rates were. I had not expected them until the next day since our slow leak was contained within a bucket. However, they did mention that they weren't too busy when I called so they dispatched a plumber unbenownst...

FAQs for septic tank service projects in Washington DC, DC
The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.
Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.
A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.
Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
