ᐅ Which type of sewage lifting system is suitable for an attic?

Hello,

I need a recommendation... I am currently converting my attic and don’t have enough pressure in the pipes to install a bathroom/WC upstairs. I thought about using a macerator pump to solve this problem. Can anyone recommend something? Or does anyone have good or bad experiences with certain products?

Hello,

I recently encountered a similar issue when I was finishing my basement.

After some research, I came across Saniboy, who manufacture small macerator pump systems.

SFA SANIBROY small macerator pump systems are used wherever wastewater needs to be disposed of. For example, in basements located below sewer level or where additional sanitary facilities are added later in a building and the wastewater needs to be transported to distant soil stacks.
“Bathroom and toilet – anywhere!”

Take a look at their website; there might be something suitable for you.

However, I would recommend letting a professional handle the installation rather than doing it yourself.

Well, wastewater is not really the problem because of the attic, I thought! But the pipe seems to be too small; at least, I can’t install the toilet. The main problem is still how to get the water up there! Are these SANIBROY systems suitable for both purposes? I’m not really a DIY expert.

Hello, you don’t need a lifting station but a booster pump system. It’s basically just a pump installed after the water meter. You might also need to install a small domestic water system, which would require an additional water tank to be set up. It’s best to ask at a specialized plumbing supplier, not a hardware store!

Best regards, Thommi

Hello Baumeister60,

I’m not a plumbing specialist myself, but it seems odd to me that the water pressure in your pipe wouldn’t be enough to carry water up to the attic with sufficient force. As far as I know, the pressure there should be around 8-10 bar (116-145 psi).
Normally, the pressure from the municipal water supply should be more than enough, unless your attic is located on the 35th floor.

In my opinion, other causes are likely at play here. How old are the water pipes in your house? Could it be that lime scale or other deposits have built up inside the pipes, narrowing the cross-section?

If I were you, I would consult a plumbing professional. They should be able to tell you what the issue is.

Hello everyone,

even though this was some time ago, I also currently need a sewage lifting unit. A macerator pump is only necessary if I actually connect the unit to the toilet, right? That’s what it says at #link removed by moderation; construction expert

Or am I missing something? I’m looking for a lifting unit that can be connected to the washing machine.

I’m looking forward to your answers.

Thanks.

Best regards
