I am looking for a pump for a basement sump pit. It should automatically turn on in case of a pipe failure or flooding, reliably vent itself, and pump through glued PVC pressure pipes with an inner diameter of about 50mm (2 inches) over a height of 2m (6.6 feet).
I have already read several reviews and, after considering Einhell and Kärcher, I ended up with the AL-KO Twin 14000 Premium, which had the best ratings. Unfortunately, according to the user manual and after contacting the manufacturer, this pump is not suitable for continuous operation or for pumping drinking water.
I suspect that this disclaimer is included in almost every pump manual, as manufacturers want to protect themselves from any claims or liabilities.
The next step would be to visit a specialist water or wastewater equipment supplier, but the pumps there are likely to cost well into the four-digit range.
Could you give me some advice on this?
My pit dimensions are 60 x 60 x 45 cm (L x W x H).
Thank you!

If I understood you correctly, you have a shaft that occasionally fills with water, which then needs to be removed. For a similar issue, I use an Einhell 4170666 GE-SP 750 LL. It works reliably, but I wouldn’t connect 50mm (2 inches) pipes to it. How much water do you think comes in?

greasechain30 Jan 2019 10:07Well, I hope the pump never actually needs to run.
But in a worst-case scenario, for example in the event of a pipe break or flooding, the pump must be able to run for several hours continuously without failing.
Regarding the pipe diameter, I wouldn’t worry too much because, at least with the common household pumps, you can’t connect larger hoses anyway, and as mentioned, my pipe is only about 2m (6.5 feet) long.
The continuous operation clause can also be found in the user manual for the GE-SP 750 LL.
However, it mainly advises against continuous running in the sense of a circulation pump...

First of all, welcome
Regarding your question.
Why should the pump be suitable for drinking water? I don’t understand that. The water being pumped out is dirty anyway and goes into the sewer.
Our wastewater pump in the sump pit, where the washing machine water flows, comes from a hardware store and cost about 30 € around 15 years ago. It needs to pump the water up 2.8 m (9 feet). By the way, the previous pump lasted about 20 years.
A few years ago, a cistern was installed without a drain. To prevent overflow, when there is too much water, about 1.5 m³ (53 cubic feet) is pumped out using a wastewater pump costing about 40 €, also from the hardware store, to make room for new water.
I also have another pump that I used to empty a pond (10 m³ (353 cubic feet)) for cleaning and have often pumped water around with it to increase oxygen levels when the air pump was not sufficient. This pump can run for hours without problems.
So I can say that only inexpensive pumps are used here, and I have not had any problems with them.
And why a pressure pipe? I use only 1” or 1 1/4” hoses. If the pump needs to be lifted, it is much easier to do with a hose than with a rigid pipe connection.

Hmm, I thought this was about the pump not being able to pump drinking water, not that the water is no longer suitable as drinking water after the pump. Strange, actually :-D
I have a lot of experience with 30 euro submersible pumps, but here I often had to shake the pump if there was an air bubble underneath during the initial suction. That risk is too high for me.
