I modified my Craftsman 4.5 HP shop vac as shown on Marv's page but must have
missed a detail. I have the downpipe as shown but it bubbles water so much that
it pops the overflow seal even with the filter in it. I drilled holes around the
bottom of the pipe near the bottom but same effect. Any suggestions?

Thanks

[Yep, that thing will bubble that water at the bottom like mad... you
really need to include the foam filter, maybe even a pair of them, over
the inner motor housing to keep the water from fouling up the works.
Additionally you only need about 1" of water above the bottom of the
down-pipe to get it to work.  If you've done those things and are still
having a water problem at the motor the only solution is to install a
couple of baffles 1/3 & 2/3 the way up the canister to stop the water
from getting up to the motor housing.  One of the advnatages to the
vac shown on my webpage is that it is very deep, probably 30", and the
dual foam filters work just fine at keeping the water down.  Keep
at it, where there's a will there's a way.
