Not Long
Only about 15 minutes or so.
I was trying for a “quickie” pump. Just wanted to dress things up a bit before I went out for the night. Since I didn’t want to have to take a shower again, I didn’t use very much lube. Just kind of greased up the inside of the adaptor, and went in dry.
15 minutes later, I had swelled up enough I had a hard time getting back out without giving myself a nice fricton burn. After the panic faded, I just used a nut driver to take it all apart, then dumped some hand lotion in the adaptor. got everythng nice and greasy and it eventually came off wth little discomfort. Still ended up taking a shower (grrrrr).
Anyway, I did the same thing agan not too long after that (No, I’m not the brghtest bulb n the box, sometimes ;) ), but I had left the suction tube in. A little reverse pressure, and POP! came right out. So, I always leave the suction tube in now.
I should just get a larger adaptor, like 1.75” to 2.0”, but Menards never seems to have them in stock, (the spot on the shelf is always empty, or has other crap in it), and I haven’t managed to make it over to the new Home Depot store just yet. Maybe this weekend, since I’m thinking about it ;) .
