Check your trap, it should be stuck in there. You will see either an s or u shaped piece of pipe right under the sink. Open it up and the bolt should be in there. I used to debag my fish over the sink and had a blenny go down the sink, he was in the trap.
The nut wasn't in the trap. :squigglemouth: I went to the auto parts store and got a stainless one that fit, but when I turn it on, the entire wet side shoots away from the glass. I will go to Lowe's tomorrow. I ordered the part from Vortech, but I need my tsunami back now...lol
For information purposes in case someone else needs a temporary replacement nut for their MP40....the size is 10-32.
The reason the wet side was flying off the glass was because the auto parts store had sold me the wrong thread (10-24). I went to Ace Hardware and they gave me the correct thread in stainless steel and it is working fine until my original part gets to me.
