"I hired Innovative Plumbing to inspect and pump my septic tank on a property I am in the process of buying. Rick the technician that came out was extremely knowledgeable about the septic system and was able to find the tank. I will definitely be hiring them again."

"I requested a quote from five companies, two of which responded. Drain Pro Services was the second to respond and the representative offered a flat fee for the service for Angie's List members. The representative indicated that he could be to my house in thirty minutes. I accepted and, indeed, the representative (Rep) arrived within thirty minutes. He was there for over two hours clearing my drain. He completed the job and we are very happy with his work."

Septic Tanks FAQs, answered by experts

Yes. Amongst the four most common types of septic tanks—plastic, fiberglass, concrete, and steel—those made of concrete are the most expensive. This is the case for a few reasons, including the fact that they’re very heavy, so pros have to use specialized equipment to install them. However, they’re also incredibly durable, making the price worth it if it’s in your budget.

Both materials are suitable for septic tanks, but concrete usually lasts longer than plastic. If you’re buying a new tank, the prices are similar for plastic ($500 to $2,500) and concrete ($700 to $2,000). However, there’s a notable difference in repair prices, with plastic tank repair costs ranging from $150 to $2,000, while concrete repairs are between $700 and $5,000.

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.

If your leach field becomes clogged or saturated, it can cause several problems with your home's septic system. The clog can cause sewage to back up into your home, leading to unpleasant odors and mess. A backed-up septic system can be a health hazard, particularly if the sewage starts to leach into the ground surrounding the leach field.

There are several ways to fix a saturated drain field, including cleaning out your septic tank, adding enzymes and additives to your drain system, and installing a larger septic system.

Since vinegar is a weak acid with a pH of two to three, it’s generally safe for septic systems. It won’t eat away at the good bacteria in your septic tank and can help break down the sludge, which is its bottom layer. However, like with everything in life, moderation is key.
