Septic Tank: Size Matters

Septic Tank: Size Matters

If you’ve ever thought about installing a septic tank or already have one, you may wonder, "Does the size of my septic tank matter?" The short answer is yes—septic tank size matters a lot! It affects how well your septic system works, how often you’ll need septic tank pumping, and even how much you might spend on septic tank repair down the line. Metro Septic Pumping explains why size matters, how to choose the right size for your home, and how a septic company can help.

Why Septic Tank Size Is Important

When the tank is too small for the waste your household produces, it quickly fills up, requiring more frequent septic tank pumping. On the flip side, if a septic tank is too large, it can cost more and take up unnecessary space. A properly sized septic tank ensures your system runs efficiently and doesn’t need constant cleaning or repair.

How Septic Tank Size Is Determined

A septic tank's size is often based on the number of bedrooms in a home since that roughly translates to the number of people living there. Larger households will generally produce more waste and thus need a larger tank. Most septic tanks hold between 750 and 1,500 gallons, but a dependable septic company can help you choose the right size for your situation.

Common Tank Sizes

• 750 Gallons - Suitable for 1-2 bedroom homes with fewer residents.
• 1,000 Gallons - Common in 3-bedroom homes, suitable for moderate-sized households.
• 1,250 Gallons - Ideal for 4-bedroom homes with a higher volume of wastewater.
• 1,500 Gallons - Perfect for larger households, typically with 5+ bedrooms.

A septic company can offer expert advice on choosing the correct size during septic tank installation.

How a Small Tank Can Cause Problems

If your septic tank is too small, it will fill up faster than it should. In addition to the added expenses, an undersized tank can lead to backups or overflows.

When wastewater doesn’t stay in the tank long enough, the solid waste doesn’t have time to settle, causing it to move out to the drain field, which can clog pipes and lead to a complete septic tank repair. To avoid these issues, a septic company will assess your home’s needs before septic tank installation to ensure you have a tank that meets your household’s demands.

What Happens with an Oversized Tank?

Although it may seem better to go big with a septic tank, there may be better options than a tank that is too large. For one, larger tanks are generally more expensive to install, and if they aren’t filled regularly, waste may stay too long.

While a larger tank may require septic tank pumping less often, it doesn’t always mean less maintenance. In some cases, septic tank cleaning may still be needed to remove excess buildup from infrequent use. A reputable septic company will ensure you’re not paying for more than you need during a septic tank installation.

Choosing the Right Tank for Your Home

The best way to ensure you get the right tank is to work with a septic company that understands how to size septic tanks based on your household’s water usage and septic needs. Here are some factors that affect the ideal septic tank size:

• Number of Residents - The more people living in your home, the larger your tank should be.
• Water Usage—High water usage, such as frequent laundry or long showers, can fill a tank faster.
• Future Plans - If you plan on adding an extra bathroom or building an addition, a larger tank might be wise.

Septic tank installation isn’t just about picking a tank and dropping it in the ground; it requires a lot of planning. The professionals at a septic company will take the time to understand your needs and make recommendations to avoid unnecessary septic tank repairs.

Maintaining the Right-Sized Tank

Once you have the right-sized tank, you’ll still need to maintain it to keep everything running smoothly. Regular septic tank cleaning and pumping are crucial for a healthy system. How often you need these services depends on your tank’s size and household’s usage, but generally, every 3 to 5 years is recommended.

When solids build up in the tank, there’s less room for wastewater, leading to slow draining and, eventually, a complete septic tank repair.

Signs It’s Time for Septic Tank Pumping

No matter the size, all septic tanks need pumping. Here are some signs to watch for that indicate it might be time to call a septic company for septic tank pumping:

• Slow Drains - If sinks, toilets, and showers drain slower than usual, the tank might be too full.
• Odors - Bad smells around your tank or drains often mean the tank is near capacity.
• Backups—If sewage is backing up into your home, it’s a clear sign that the tank needs pumping.
• Pooling Water - Water gathering around the tank or drain field could mean the tank is full or leaking.

How to Avoid Frequent Septic Tank Repair

Proper maintenance is key to avoiding frequent septic tank repair. Regular septic tank cleaning removes waste that has settled on the tank floor and keeps the tank in good condition. Avoid flushing things like wipes, feminine hygiene products, or other non-biodegradable items, as these can clog your tank and require repair.

Metro Septic Pumping

Choosing the right size septic tank is more important than many people realize. It can affect how well your system operates, how often you need septic tank pumping from a service like Metro Septic Pumping, and even the overall lifespan of your septic system. An improperly sized tank can lead to backups, foul odors, and expensive septic tank repair.
