I wish I took pics durring it.
It is really easy to do and describe without pics. Here is the step-by-step.
1. Unplug pump and remove from skimmer (would be tough to do when running)!
sorry, coffee not kicked in yet.
2. Remove intake housing and impeller assembly.
3. Carefully cut pins off of needlewheel. I used a pair of fine wirecutters but a dremmel with a cutting wheel would work even better (don't have one). Try getting them to about 1/16 - 1/8 inch in height. I don't cut them flush as I feel they help hold the mesh in place.
4. Cut 3 squares of mesh slightly larger than impeller wheel.
5. Layer the mesh 3 layers thick. Using a fine pair of scissors, cut a 1/4" hole in center so it can fit over center shaft. Does not have to be size of shaft as it will squeeze over it and help hold in place.
6. Secure with two zipties using the holes already in the impeller. Have the secure portion facing out (see above pic) to prevent scraping back of impeller housing. Do NOT overtighten!!! This can cause mesh to bow outward. Just tight enough to secure mesh to wheel and keep it flat.
7. Using a pair of scissors, trim mesh around wheel edge so it is nice and round.
8. Place back in pump and reassembel housing. Do a "dry test" where you plug it in and see if it spins. If not, you may have a corner of mesh catching on something.
9. Place back into skimmer assembly and connect everything.
10. Plug back in. You may have to blow some air into venturi hose as I found there is some sort of fluid lock when first starting up.
11. Re-tune skimmer as your skimmate will be WAY more!!
That is it. Easy to do and takes about 20 minutes. My mistake was overtightening the zipties and that caused the mesh to bow outward and catch on the housing. If that happens, cut the ties and put 2 new ones on.
For the venturi intake sizing, just find what drillbit size fits in there and go up by 1/32" (1/64 even better) and bore it out SLOWLY. You can even do it by hand if you have a hand tap that can grip the drillbit. Go up a total of 1/16" in diameter (2-1/32 bits or 4-1/64 bit sizes) This allows even more air into intake and furthur increases performance.
Hope this helps!!
