Heavy-Duty Grinder Pump System Solves Below-Grade Challenge for North Shore Lodge’s Basement Renovation

Case Study | December 2023
When general manager Jason Weddingfeld of North Shore Lodge decided to finish a walk-out basement, he chose a pre-assembled simplex grinder pump system to move wastewater vertically up to the sewer line on the primary floor.

Problem

GRAND LAKE, COLORADO — North Shore Lodge is a charming nine-unit rental property located on the shores of Lake Granby. Jason Weddingfeld, an experienced property manager, has managed the lodge since early 2023. Upon taking over, Weddingfeld and his staff initiated a project to complete the unfinished basement to increase the property’s value and profitability.

The project was multifaceted; one of the primary goals was to create a manager’s apartment; the other was to add a conference room to host small corporate events and meetings. Adding these spaces would make the property more versatile and appealing, boosting its profitability.

The property currently functions as a short-term rental for overnight lodging, and each unit has multiple bedrooms and kitchens, distinguishing it from conventional hotels or motels. As the property has only one level with a walk-out basement, Weddingfeld aimed to finish a large portion of the basement to give it a more complete look.

The project wasn’t without challenges. The main obstacle: The basement grade sat below the existing sewer line. As a result, Weddingfeld had to find a plumbing solution that would allow him to pump the wastewater from new basement fixtures up to an existing sewer line located on the primary floor.


Solution

Weddingfeld, upon the recommendation of his contractor, contacted SFA Saniflo, a leading manufacturer of above-floor plumbing solutions. After thorough research, Weddingfeld and his contractor opted to install the Sanicubic 1, a pre-assembled simplex (one pump) grinder system designed to pump wastewater from multiple fixtures in a building structure.

In the North Shore Lodge basement project, drain lines from six fixtures tie into the grinder: two toilets, two bathroom sinks, a shower enclosure, and a kitchen sink.

About the Sanicubic 1 simplex grinder

The Sanicubic 1 is a heavy-duty simplex (one pump) grinder system with 1 HP motor. It is specifically designed to pump away waste water from multiple bathrooms and fixtures in an entire building structure.

This system can discharge waste up to 36 feet vertically and/or 328 feet horizontally. It is equipped with a heavy-duty grinder system, making it suitable for uncontrolled environments in both residential and commercial applications, such as rental units, offices, and warehouses where the plumbing system will likely receive rough treatment.

For example, the Sanicubic 1 is specially designed to handle larger sanitary products that may have been inadvertently or mistakenly flushed down the toilet; e.g., condoms, sanitary napkins, q-tips, dental floss, and similar items.

Here is how the new basement is laid out:

  • The basement includes a kitchenette with a sink on one side of the room.
  • Adjacent to the kitchenette is a three-quarter bathroom with a toilet and shower enclosure.
  • Connected to this bathroom is another room separated by a partial wall. The installer dug a pit through the concrete floor for the grinder pump.
  • A half-bathroom is next to the three-quarter bathroom, creating a north-to-south setup.


Here’s how the installer configured the plumbing in the basement:

  • The wastewater from the six fixtures feeds into the grinder pump unit via a new drain line (two 3-inch pipes that connect to a 4-inch pipe) installed below a new subfloor.
  • The grinder pump is situated between the two bathrooms and the kitchenette.
  • A motor inside of the pump has a high-performance grinding system and a fast-rotating cutting blade to reduce solids in the wastewater stream from the toilets, showers, and sinks.
  • The wastewater is pumped from the grinder via a 1½-inch discharge pipe connected to its top. The discharge pipe runs five feet vertically and three feet horizontally and eventually connects to the existing sewer line, which exits the building and links to the mainline.
  • A venting pipe runs vertically from the top of the grinder pump to the outside of the building, adhering to building requirements. Since the pump is inside a pit, the Saniflo pump was the perfect solution since all main components, such as the motor and pressure chamber, are easily accessible from the top of the pump.


Results

After opening the concrete for the unit installation, there were no further complications once the grinder pump was in place.

“It was very easy,” emphasized Weddingfeld, “There was no problem connecting the unit to our newly installed plumbing system.”

Since the installation, the grinder pump has undergone extensive stress testing with all the fixtures. There is complete confidence that the fixtures alongside the Sanicubic 1 unit can handle whatever happens to be put into them.
