I recenlty acuired a new in the box Eheim 2229 but it has no instruction book.

The online manual says nothing about this part, but here is my question.

There is a orifice that goes into the pump head that says the installed orifice is for 33" to 47" water level height from bottom of canister. The additional orifice says to replace if the water level is 47" to 55"

Question 1:
What is the purpose of this orifice?

Question 2:
If I am using this canister on a 150 gallon water level height of 59", will the canister leak or not function?

MAybe this orifice is what makes the wave motion,...I dont know.

The online manual says nothing about it. It jsut talks about how to connect hoses n stuff.

I will most likely build a stool or something to put the canister on so that I am under the 55", I want to check my options here.

Thanks for any input

The height requirement is important. I have had the 2229 for about 3 years. It was originally setup on my 75G tank which is 48" from tank rim to bottom of filter. It works great but then...

I moved the filter to my 220G tank which is 58" from tank rim to bottom of filter(I added length to the hoses so it would reach). The filter would not operate properly. I had to set the filter on a plastic milk crate & remove the extra hose length I added. Only then did it work right.

I don't remember which one has the smaller orifice but next time I clean it out I will make a note of it. Hope this helps.

The orifice that is the same color as the pump head was the installed one for 33" to 47"

The clear plastic one is for 47" to 55"

When you operated it on the 220 gallon, which orifice did you have installed and did the filter leak, or did it just not drain/re-fill?

Thanks for the help.

The clear orifice. Did not leak, just wouldn't drain/refill.
