The contraption you see below closes a wet/dry vac's liquid exit. I'd like to replace it with "something" that connects to a water hose.

contraption

What would that "something" be called?

I would attach a valve to the other end of the water hose. If such a thing (hose + valve + thing) is readily available, it would be even better.

I can go to my hardware store and ask them, but I know from experience that they'll make me walk back and forth between gardening and plumbing until I can just identify what I'm looking for. Hence I'd much rather ask here, and perhaps just order online.

Update

With the keywords "drain hose adapter" I have now identified what would be ideal.

I'm looking for something exactly like this

pump

but without the pump. Do they make it or do I have to DIY?

  • Check the inner diameter of the cap - I think it looks about 2 1/2 inches. You'll want plumbing - a 2 1/2" to 3/4" conversion but I don't think you'll find one unless you get multiple parts. I guess the idea is to push the liquid out the hose instead of having to lift / dump it by hand? – The Evil Greebo Jul 3 '17 at 19:26
  • @TheEvilGreebo Exactly! I'm a puzzled what I'm looking for doesn't come with every shop vac that takes liquids. If I raise the shopvac just a bit off the ground, it'll be easy to drain what's in it by gravity. Good guess too: it is indeed 2 1/2". – Calaf Jul 3 '17 at 19:30
  • You do understand it won't drain while the vac is running, yes? – Harper - Reinstate Monica Jul 3 '17 at 21:03
  • @Harper Thanks. lol... there was a day when I was clueless about how these things work, but I now have a grasp that they're based on the "suction principle", or whatever the formal name for this is. – Calaf Jul 3 '17 at 21:50
  • The point of the pump is that it will flow while the vac is on. Gravity won't do that (unless you can give the hose 30' of head.) You'll want a check valve in any case. – Harper - Reinstate Monica Jul 4 '17 at 3:28

Just look for a Drain Adapter Kit for Garden Hoses. It may vary by brand.
