When designing a home with a basement or a lower-level plumbing system, a sanitary sump pump is often required to manage wastewater effectively. Choosing the right sump pump system is crucial for long-term functionality, maintenance ease, and overall system reliability. In this guide, we will outline three main options for sanitary sump pumps, discussing their pros and cons to help you make an informed decision.

Why Do You Need a Sanitary Sump Pump?

A sanitary sump pump is designed to collect wastewater from below-grade plumbing fixtures, such as basement bathrooms, laundry rooms, or kitchens, and pump it to the main sewer line. Without a properly installed sump pump, wastewater cannot flow by gravity, leading to potential drainage issues and health hazards.

Sanitary Sump Pump Options

There are three primary options for sump pump installation, each suited to different situations. Your choice will depend on budget, available space, and maintenance preferences.

1. Concrete Sump Outside

• A concrete sump is installed outside the home, typically in the yard. This is the most robust but also the most expensive option due to the construction and sealing requirements.
• It provides a large storage volume and can be installed early in the excavation and backfill phase of construction.
• However, the sump is much deeper than indoor options, often requiring a heavy-duty steel lid secured with bolts, which can be a trip hazard.
• Maintaining the pumps can be cumbersome due to the sump’s depth and exposure to outdoor conditions.
• While this setup offers strong protection, it also comes with higher costs, requiring proper sealing to prevent contamination and ensuring accessibility during extreme weather conditions.

2. Fiberglass Sump in Sunken Patio (Recommended Option)

• A fiberglass sump installed in a sunken patio offers a cost-effective and easily accessible solution.
• This system is typically around five feet deep and 30 inches in diameter, with a fiberglass lid secured with bolts for easy maintenance.
• Compared to a concrete sump, this option requires less excavation while still providing good accessibility for servicing.
• However, since it is not fully buried, it offers slightly less protection than a concrete sump.
• Additionally, proper drainage planning is essential to prevent flooding around the patio.

3. Fiberglass Integrated Sump (Liberty System – Indoor Installation)

• For homes with limited outdoor space, an indoor sump system is a viable alternative.
• Typically installed under a staircase or in a mechanical room, this system utilizes a pre-designed fiberglass sump from Liberty Pumps.
• This option is compact, space-efficient, and requires no outdoor excavation.
• However, all maintenance must be performed indoors, which may not be ideal.
• Without proper venting, odors can become an issue, and the smaller sump volume means the pumps may cycle more frequently.

How to Choose the Best Option for Your Home

The best sump pump system depends on several factors. If budget is a key consideration, fiberglass sumps in a sunken patio provide an effective balance between cost and functionality. Concrete sumps, while the most expensive, offer durability and large storage capacity. If outdoor space is limited, an indoor sump may be the most practical choice, though it comes with maintenance and odor concerns. Additionally, consider ease of maintenance—if accessibility is important, a sunken patio sump is often the best choice.
