Sump pump setups connected to multiple drains like sinks, toilets, and showers can sometimes cause that nasty rotten egg smell, especially if your venting or drainage isn’t quite right.

So, here’s the thing: if your shower smells like rotten eggs when running, it’s usually because sewer gases are sneaking back up through the drain. Since you mentioned you didn’t drill a weep hole yet, that might be a big part of the problem. The weep hole lets air escape from the pump’s discharge pipe, preventing vacuum pressure that can suck water out of the trap. without water in the trap, the sewer gases come straight up. Also, make sure all your traps are holding water properly; if any dry out, that’s an open door for smells. Double-check that the sump pump’s air vent is installed correctly and not blocked because vents are super important for balancing air pressure and preventing gas backups. Since your sump pump is new. just two or three months old. there’s a good chance the issue is more about venting or trap seals than the pump itself. And remember, you shouldn’t be using a Provent on a sump pump; those are for sewage ejector pumps, which handle solids differently. If you’re mixing those up, it could mess with how the system vents and drains. Lastly, if smell problems persist, consider getting a plumbing pro to inspect your setup, just to make sure everything’s up to code and working right.

One of the biggest mistakes people make when dealing with sump pump odors is skipping the weep hole. without it, air pressure builds up and sucks water from traps, letting sewer gas through. Another common issue is confusing sump pumps with sewage ejector pumps; using parts like Provent on the wrong pump causes venting problems and odors. Third, people often overlook dry traps in connected drains; any dry trap means no water seal to block smells, so keeping them filled is key. Fix these by drilling the proper weep hole for your pump model, verifying you have the right pump type for your application, and regularly running water through all traps to keep them sealed.
