roni April 5, 2011 April 5, 2011 Okay, couple issues: First, i've got a sicce 2500 needle wheel but it seems that the volute won't stay put. i've also got an extra piece out so that may be the issue i think the white piece i'm holding should snap into the piece i've got in the same pic and it seems to fit easily, but if i put that in, the two pieces don't close. what am i doing wrong? basically i think the volute isn't locking into the pump assembly Second issue is that when i run the pump. if i hold the volute in place by hand, i get good performance but it seems that it's kicking bubbles out of the gate valve. i have the pump going into the inner chamber and the gate valve in the hole on the outside (not into the inner chamber). these are probably stupid questions but after struggling for the last hour, i'm hoping for some guidance. thanks in advance.
Origami April 5, 2011 April 5, 2011 The insert goes on the exterior side of the piece in the first picture, the volute cover (on the back side of the picture). It should not, in any way, interfere with assembly. Is there an o-ring around the volute cover? You probably realize this, but it's a snug fit sometimes.

Tom, thanks! does the insert go in with the orientation in the pic or flipped? i think what i'm noticing is that the volute and pump assembly seems to not snap into place and hold. after a few seconds without me holding it, it seems that the volute comes off and then the impeller is free.
Origami April 5, 2011 April 5, 2011 It goes in on the other side. Are you locking the volute cover in place with a twist?
Origami April 5, 2011 April 5, 2011 The insert, by the way, should snap into the volute cover and hold by itself. (At least, some designs, snap in - others require glue. I don't know what the maker of that insert did.) If it doesn't snap in, try putting a few wraps of teflon tape on it and seeing if that won't snug it up a bit.
roni April 5, 2011 Author April 5, 2011 It goes in on the other side. Are you locking the volute cover in place with a twist? yeah, put it in and twisted. i wonder if i need to pull out or something to get it to snap into place. will mess with it tonight.
Origami April 5, 2011 April 5, 2011 When you twist it in place, it will pull down into the volute housing. You'll see the ears on the cover slide under a ramp-like thread structure built into the side of the volute housing.
