hornbach201625 Jul 2016 23:01I hope you can help me. We are currently planning our new single-family house with a basement and are looking for the right lifting station from Kessel. We will design a room in the basement as a future shower bathroom for the children and will install the corresponding drainage pipes beneath the slab, but for financial reasons, we definitely will not build it out or use it as a shower bathroom for at least the next 10 years. The only other room with wastewater below the backflow level is the utility room with the washing machine, dryer, and a small hand washbasin.
Our basement builder recommended the Kessel Aqualift F Compact because of the planned toilet in the shower bathroom and wants to install it under the slab, as it is considered a “clean and reliable” solution. Since the lifting station will definitely not have to handle wastewater containing fecal matter for the next 10 years, we would prefer to install a more affordable lifting station for now and then replace it with a fecal-capable lifting station like the Aqualift F Compact at a later time. I have read that a pump sump is no longer state of the art, so the idea was to install a similar but non-fecal-capable lifting station during the basement construction and then swap it out for a fecal-capable one like the Aqualift F Compact after the bathroom is built in 10 years.
Is there a comparable, more affordable lifting station to the Aqualift F Compact that we could easily replace later? What solution would you recommend?
Thank you very much in advance for your response.

Gartenfreund26 Jul 2016 05:33I would use a pump sump. It is cost-effective and easy for anyone to clean and inspect. And if the pump should fail, you can simply go to the nearest hardware store and buy a new one for a low price. However, I would protect the walls from dirty water somehow (pond liner, plastic basin, etc.) because, as I can see here myself, the concrete gets somewhat dirty and that is difficult to clean, which is certainly not very nice if a sewage lifting system is installed at some point.
However, I would also reconsider whether a toilet is really necessary down there or if it can be omitted. From my experience, I have never missed having a toilet in the basement.

Sebastian7926 Jul 2016 07:40I love my basement toilet – I use it the most so far.
However, discharging fecal matter directly into a sump pit is a bad idea – it needs to be completely sealed. You also have to provide ventilation, which is more difficult to achieve in this setup.
We have a sump pit, but only wastewater from the shower, sink, and washing machine flows into it. It is secured by two pumps that switch monthly.
The toilet drains through a small macerator pump system.

We have a Saniboy for heating, the sink, and the washing machine. It can even handle sewage. It costs 400 € and hasn’t caused any issues in 3 years. In our case, it is installed surface-mounted in the basement. If it’s located under the slab, how would you access it then? A sump pump can quickly complicate the KfW energy calculations, but it has the advantage that if the washing machine or something else ever leaks, you can dry out the basement quickly. Our basement contractor no longer installs sump pumps, so that was not an option for us from the start.

Thermal bridge? Certainly, but it’s absolutely minimal given the depth and size. You could simply cover it with an insulated cap otherwise.

Thermal bridge? Sure, but absolutely minimal given the depth and size. You can just put an insulated cover over it I’m not up to date on this. The pump sumps I know are about 50cm (20 inches) deep—so basically deeper than the entire basement floor structure. In my case, there is insulation below the screed plus the screed itself installed—so you end up with a thermal bridge of 50 by 50cm (20 by 20 inches, the size of the pump sump). Whether that’s significant—I have no idea—I haven’t looked into it further.
