Sump Pump for toilet

OK all you sump experts. This will probably be easy for you.


Heres the situation:
Basement bath and laundry.
4" building drain exits the house about 5' above the basement floor.

The basement fixtures are pumped up to the building drain via a sump pump. The fixtures include 1 toilet, 3 sinks, 1 closhes-washer, 1 bath-tub.

The discharge line from the sump to the building drain is only two inches. This seems too small to me. My intuition tells me the discharge should be 3" minimum to handle the toilet debris.

What are your opinions?

Thanks,
Ed

Is it really a sump pump or an Ejector Pump? Ejector Pumps are usually 2" discharge

I do not know. Can you tell me what the difference is?

Ed:


If it is handling toilet effluent, it is a grinder pump. These pumps are designed by the manufacturer with a 2 or 3 inch threaded discharge connection.

Grinder sump is a sealed sump pump with a 2 or 3 inch discharge and a 2 or 3 inch vent connection back to the sanitary outlet line.

Thanks Joseph,


There IS a 2" vent as well as a 2" discharge.

So, If this is a grinder pump then would a 2" discharge be sufficient to handle all these fixtures?

I did try to overload the pump by draining the clotheswasher and the tub and the toilet at the same time. (No problem handling the volume)

The vent, discharge and one of the drains drops right through the top of the well...so the pump itself was inaccessable for inspection. Is there any way short of visual inspection to determine if this is indeed a grinder pump and is properly sized?

Thanks again,
Ed

Thanks for the info.

Ed:


I do not open or break the seal of the sump lid. I do not break the pipe connections.

I generally limit my inspection to running the water to verify pump operation noting any excessive noise, short cycling of the pump, pump cavitation from running dry or signs of leakage (Liquid or Odor).
