We want a bathroom down there
Ejector pumps, upflush toilets, smells and permits for a bathroom below the main floor.
A basement bathroom is one of the most popular projects in older Maryland houses, and one of the most misunderstood. The big question is height. If the new toilet and shower sit below the sewer line leaving the house, gravity can't carry the waste out, and a pump has to lift it.
Building a bathroom below the sewer line explains the options. If the words "ejector" and "sump" are getting mixed up, this comparison sorts them out. A compact macerating unit may be enough for a half bath; see whether an upflush toilet makes sense.
The model plumbing code calls for waste that can't drain by gravity to go into a tightly covered and vented sump before it's pumped up. That's licensed, permitted work. In Montgomery and Prince George's, the permit runs through WSSC Water; elsewhere it's the county. The permit question covers who to ask.
The questions
What's the difference between an ejector pump and a sump pump?
Ejector pump vs sump pump comes down to what's in the pit. An ejector lifts toilet and drain waste up into the sewer; a sump pump sends clean groundwater outside.
Can we put a bathroom in a basement that sits below the sewer line?
Yes, a basement bathroom below the sewer line is doable. The waste just has to be pumped up, from a sealed ejector basin in the slab or an upflush macerating unit, installed by a licensed plumber with a permit.
Is an upflush toilet a good idea for our basement?
An upflush toilet is a good idea when you want one toilet, maybe a sink, below the sewer line without breaking up the slab. For a full bath or laundry, an ejector basin is built for heavier duty.
The alarm on our ejector pump is going off. What now?
An ejector pump alarm means sewage in the basin has climbed above its normal level. Stop running water into anything that drains downstairs, stay clear of any overflow, and get a licensed plumber out.
Why does the basement bathroom smell even though it's clean?
A basement bathroom that smells like sewer while looking spotless has a gas problem, not a cleaning problem: usually a dried-out trap, an ejector lid that isn't sealed, a vent that isn't working, or plain damp.
Do we need a permit to add a basement bathroom in Maryland?
Yes. A basement bathroom permit is needed in Maryland, and who issues it depends on your address: WSSC Water in Montgomery and Prince George's, and the county or city permit office everywhere else in the region.
