Sewage ejectors have been available on the market for many years. Anyone that has one installed can tell you that in the event that a gravity drain being available, this is the next best option. These style of toilets basically have a need for a water supply and the drain can be piped virtually to anywhere depending on the internal pump size. That being said, if you were thinking of having a basement washroom in a house that was on a septic system but did not want to install a sewage pit or ejector, this was the answer.
Draincom experts have installed many of these style of toilets over the years and they are a very effective product.
On one such occasion we installed a system consisting of a toilet and a lavatory basin. The water supply was available and very easy to tie into, we decided to use Pex. After the water lines were run, the venting lines were run in ABS piping to the available 2" connection provided and the drain was run over to the horizontal out to the septic tank. All in all, the job did not require a lot of demolition, did not require a lot of damage nor was the job very time consuming.
Now when it comes to Ejection pumps and sanitary pits, this can be where you need to call in a Professional Plumber. There are many things that can happen with a sewage ejection system and to get right to it, it is raw human waste. I was on a job in a commercial plaza that had such a pit and the pump alarms were sounding because the pit had filled up to a point where it was overflowing.
We arrived on site expecting to see a very nasty and large mess, but to our surprise there was very little. We opened the lid and the pit was sure full!! The next step is the little bit nasty one... first the electrical was shut down for safety, next was disconnecting the piping and the removal of the ejector itself. I carefully prepared with cut proof rubber gloves and a second set under that for safety as you never know what you might find. Being that this place was a commercial unit with many uses, there was no indication of what it could have been.
After the pump was removed from the pit.... I was astounded!! There was a full set of long johns, the full suit type, jammed into the impeller of the pump. Now this in itself is not a really big problem but with the amount of electricity that it takes to run such a large pump, the likelihood of the motor being fried was pretty high and it almost smelled burned... well of what I could smell. I dismantled the volute portion of the pump and proceeded to remove all the blockages from the inner workings.
As a precaution I had decided to set the pump in a safe area and to run it outside the pit to make sure that the motor was not damaged in any way. After actuating the floats, magically it turned over. After a few more small tests I was certain that it would be ok to re-install. We then lowered it back inside the sanitary pit and connected all the previously disconnected piping. After re initializing the power, the pit seemed to drain very quickly and effortlessly.
