I can't for the life of me find a Water Aspirator for a faucet anywere in EU. Does anyone here have one they could sell to me? Thank you.

Why would you use a faucet with a water aspirator? This is a huge squandering of water. Use a pail and a water pump.

So I would just need to use a bucket of water and a water pump? The water pump I have is not so strong, so I geuss I assumed that water pumps aren't very strong. How many PSI do you think would be good for a water pump?

You not only need "PSI" but "gph" as well. :-)

Aspirators require a decent water pressure and water flow rate too in order to work properly!
My pump says: 5-30 l/min, 0.5 - 3 bar; 3.6 bar max. 400 W (or something like that).

I use a bigger (120 liter (180 liter?)) plastic drum as water reservoir for this pump.

My aspirator is an "el cheapo" plastic model, looks like a small kids toy. Cost was about 7 Euros a few years ago. It pulls a pleasant vacuum, can boil water around 18 Celsius.

I use a farmer appliance, one of those made to pump and spread phytosanitary treatments into fields. It’s chemically resistant, puts out a decent pressure (8 bar, IINM) and works on 12 V DC, which allows me to control the vacuum using a variable DC power supply.

Also remember that the colder your water is, the better is the vacuum.

Thank you Keras abd Pumukli!

Nurdrage has an excellent video on aspiration pumps. He covers the different types, water pumps to use, and level of vacuum achieved.
