Basement Bath Waste Basin/Sump

Has anyone had much experience with these specialized pumps that are sealed to prevent fumes and also designed to handle solids? I have a client whose pump has failed. (Absolutely no access to it at time of inspection… disclosed by seller as recently replaced). I suspect an average sump pump had been installed vs. one designed for solids… Also, he had a plumber come in and say it was illegal to have a sump like this… My understanding is as long as it is sealed and capable of handling the solids vs. liquids only… Any thoughts? Sorry no photos… other than the piping coming out of the floor…

Jeff,


What you are describing is a Sewage Ejection Pump. These pumps are the answer to installing a bathroom and/or laundry room in your basement or anywhere else that is below your main sewer/septic lines. Water and sewage waste can go uphill (from the pump ejection) which means you can install a bathroom almost anywhere in the basement area.

It?s not intended to be replaced with a sump pump. It?s completely different.

Never attempt to remove the cover to this unit for inspection. All I do is run every water supply until I hear this pump go into operation. If it fails to operate, I simply write it up.

This is what a typical Sewage Ejector Pump looks like.

great picture dave thanks… that is exactly it… for some reason, there was no cover on this particular one… although I would not have knows since it was beneath a raised floor (carpeted)… now that it has failed the new owner is calling… 6 months later… his plumber said it was illegal… without a cover I would agree… How large of a tank do these run?

These are usually 30 gallon holding tanks in typical residential installations, but the ejector pump size does vary.

Is that what I’m looking at here (with cover?) I didn’t see any other possible place for the waste lines from the full bath in the adjacent room to go - I didn’t think to listen for it to kick on. I just tried to put 2 and 2 together, and it seemed to make sense.

Joe,


You have the same exact pump in your pic.

The waste piping is laid out and buried under that concrete floor so all waste in that lower floor area will be carried and diverted into that ejector pump hole you're looking at.

When the tank gets to a certain level, the pump kicks on. Always test these pumps... I do. Flush the toilet and run every faucet you can until you can here the swishing of the water being pumped up that white PVC pipe.
