What We Do

Complete Septic Service
Under One Roof

From a routine pump out to a full system replacement, our crews handle the whole job with our own trucks and our own equipment. No subcontractors, no runaround.

Septic Pumping & Cleaning

Routine pump outs on residential and commercial systems. Most homes should be pumped every two to three years to keep solids out of the drain field.

Why King & Sons

A Family Name On
Every Truck

We started in 1980 with one truck and a phone number, and the name on the tank is still the name of the family who runs the company. That is why our crews treat a Tuesday pump out the same way they treat a full installation.

Septic work is not glamorous. It is worth doing right, because the cost of doing it wrong shows up in your yard, in your basement and in your wallet.

How Your System Works

Everything that leaves your house makes three stops. When one of them backs up, the whole system feels it. Here is the short version.

1

The Septic Tank

Waste leaves the house and settles. Solids drop to the bottom, grease floats to the top and the liquid in the middle moves on. Those solids build up, which is why the tank has to be pumped.

2

The Distribution Box

The liquid passes into the D box, which splits the flow evenly across the lines running out into your yard. A cracked or tilted D box overloads one line and starves the rest.

3

The Drain Field

The lines release the liquid into the soil, where the ground filters it naturally. Let solids reach the field and it clogs, and replacing a drain field costs many times what a pump out does.

Most Maryland homes should be pumped every two to three years. If you cannot remember your last one, it is time.
