You will need to hire a skilled plumber to replace the septic distribution cost.
As such, the cost will vary depending on the rate of the plumber.
On average, septic distribution box replacement shouldn’t cost more than $2,000 and it can go for as low as $550.
The main determinant of the final price is the rate charged by your plumber.
Some plumbers may charge as much as $1,000 for their labor alone.
The table below gives a better picture of the average costs.
| Lowest cost | Average (National) cost | Highest cost |
| $550 | $1000 | $1,800 |
It is not advisable to go the DIY route when replacing the septic distribution box.
The septic tank has lots of toxic fumes that can be a health hazard.
Additionally, if not done right, the septic system may eventually fail which will end up costing much more than you were trying to save.
Type Of Septic Distribution Boxes (And How They Affect The Cost)
Just like septic tanks, distribution boxes can be made of concrete, plastic, or fiberglass.
As you may have guessed, the material used will impact the price.
For instance, concrete D-boxes will cost more than plastic and fiberglass ones.
However, concrete D-boxes are more durable and can last for up to 30 years as long as they are managed well.
Here is a breakdown of the different types of distribution boxes and an estimate of what they will cost.
| Type f D-Box | Lowest cost | Average cost | Highest cost |
| Concrete | $150 | $225 | $300 |
| Plastic/polythene | $75 | $137 | $200 |
| Fiberglass | $50 | $125 | $200 |
Other Costs To Consider
As we have already established, the labor cost might be the most expensive part of replacing your septic distribution box.
A septic tank professional may charge anything from $500 – $1500 depending on how much work the project needs.
On average, D-box replacement will need around 30-40 hours.
The following are some of the additional costs that you may have to budget for:
Size Of The Distribution Box
The size of the distribution box will be determined by the size of your leach field.
For instance, a 4-hole distribution box is ideal for 3 field lines, a 6-hole D-box is ideal for 5 field lines, and so forth.
The larger the box, the more it will cost. For instance, a 4-hole plastic D-box may go for around $70 while a 6-hole plastic D-box will go for approximately $115.
Permits
Every region has a permitting authority that stipulates the procedures and permits required for septic system repairs, upgrades, and installations.
The exact cost of the permit will depend on your local permitting authority.
For instance, permits for Florida dwellers cost $300 while New Yorkers may have to part with as much as $500.

Other Factors That May Affect The Cost Of Septic Distribution Box Replacement
Apart from labor, permits, and size, some other factors will determine the price of the septic distribution box replacement.
These include:
State Of The Drain Field
Before you embark on replacing the distribution box, you will want to check your system to figure out if there is a problem.
If it is just normal wear and tear, then you have no reason to worry.
However, if you are replacing the d-box because of a failed or failing system, then you may need to take care of other issues as well.
For instance, if the tank was full, you will also need to pump it, which will set you back an extra $400 add or take.

Hourly Rate
The average hourly rate of your contractor is another important factor.
These rates are usually determined by factors like experience and location.
A more experienced plumber will charge more than a newbie.
Additionally, more expensive regions like New York will attract higher hourly rates than other cheaper locations.
Warranty
There are two types of warranties that may bring your cost down – the D-box warranty and home warranties.
Most d-Box companies have warranties that last a couple of years and if it fails before the warranty expires, you may qualify for a free replacement.
However, it is highly unlikely since most D-Boxes last for up to 30 years.
Some homeowners usually purchase a home warranty which allows them to carry out home repairs without spending additional money.
If you have such a warranty, it will cover a septic d-box replacement as well, which means you won’t need to spend extra on the project.
DIY Vs Hiring A Professional
Septic distribution box replacement is a complex job and should be left for the pros.
Apart from the laborious work, you have to know how to properly disassemble the old box and install the new one.
Septic tank professionals are trained and well-equipped for this task and will therefore do the job well without making costly mistakes.
So, even though you may think of DIYing the project to save some cash, the danger of making a costly mistake is too high.
How To Save Money On Septic Distribution Box Replacement Cost
There are a couple of things you can do to save money on the D-Box replacement.
The first is to ask for several quotes. As a rule of thumb, don’t hire the first contractor you get a quote from but compare the rates with at least two others to ensure you are getting a good deal.
Secondly, you can save a couple of bucks by going for cheaper boxes.
For instance, you can opt for a plastic box instead of a concrete one.
Another tip is to maintain your septic system regularly.
Proper maintenance of your septic system can help prevent the need for costly repairs or replacements in the future.
