Excuse my hands, I did a lot of die polishing this day (lots of black gunk) but here is how you fix the Via Aqua. I was going to do a FAQ but now in an opportune moment.
Here you see the lowly Via Aqua, spat upon and shunned by hardcore water dogs but it can be a perfectly usable and very quiet pump with a bit of help.
In the pic you see it disassembled and its 2 piece impeller. The reason these pumps make noise is because of the easy start device built into the impeller. It is a key on both pieces that allows the impeller to rotate ¾ of a turn before engagement. This needs to be dampened to quiet the pump. In the right of the pic you see I have two impeller disassembly tools (commonly known as Dremel tool wrenches) they fit perfectly under the impeller.


Using the tool pry down and the impeller will pop apart (catch it because it will fly).


Here you see the engagement key, there is one inside the impeller as well. What needs to be done is install piece of something in that collar that will hold against the inside wall of the impeller and act as a “brake”. 1/8” tubing is the perfect thickness for this.



Cut and trim a piece of tubing that will fit around and in the collar, big enough so the ends meet.


Now holding the piece of tubing together start to push the impeller together enough to let go of the tubing.


With two hands and even pressure snap the impeller back together, You now see that it still turns but is dampened resulting in a quiet running pump. This same method may work on other brands of pumps as well with similar construction.
