"Excellent work. By Code gave me an estimate to remove and replace my 50 gallon water heater for $1454.00 on Saturday over the phone, then replaced it on Sunday the following day with 2 expert plumbers. They are best and most honest and efficient plumbers in Miami. I highly recommend them and will hire them again for all my plumbing needs."

"Barrett's Plumbing saved me a ton of headaches and money. Every 2-3 weeks I used to have to call someone to pump or clear my drain, ranging anywhere from $250-$300. Barrett's Plumbing was the only one to actually realize that I needed a whole new septic tank. Finally I no longer have to worry about any backups or flooding in my house."

"Company provided next-day service to clean out our septic tank. They showed up on time and quickly located the lid without having to tear up our yard. Both men were friendly, cheerful and displayed a positive attitude about their work. In no time, they were done with the job. Finally, the price came in at $20 less than quoted on the phone. Overall, a great experience. In two years I will definitely call on Jason's again."

Septic Tanks FAQs, answered by experts

A septic tank lid is often 1 foot underground, but it could be just 4 inches from the surface or 4 feet deep. For septic tank lids that are closer to the surface, you’ll have an easier time locating them just by looking for signs in the yard or using a metal probe. But for septic tanks that are buried deeper underground, you’ll need to hire a pro with specialized equipment to track down the lid without risk of damaging utility lines.

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.

Start by finding the septic tank, marked by an access lid near your home. From there, the drain field extends outward in a series of trenches. Look for greener, lusher grass, as drain fields promote plant growth due to moisture and fertilizer. You can also check property records, use a soil probe to detect damp soil, or hire a septic professional with ground-penetrating radar equipment to map the drain field’s location.

Your garbage disposal will only affect the health of your septic tank if you’re using it too frequently, or filling it with organic waste that doesn’t fully break down. If the tank fills up with too many solids, the bacteria won’t have enough time to consume it before more is added, which can lead to an overflow in the drain field. Your tank will need to be pumped more frequently with excessive or improper garbage disposal use.

Pump the tank every 3-5 years, avoid flushing non-degradable items, and address leaks promptly to extend system life.
