Shop Vac Drain Plug – Hose Connection
Category: Shop vac shop, workshop
Accessory or Product Modification
Problem: I have already modified my shop vac so that there was a drain plug in the bottom, which meant that when I vacuumed up some water I could just take out the plug, and let it drain without having to carry it someplace or to take the top off and lift or roll the shop vac full of water. This is fine, when I am working outside, and want to use the shop vac to take water from a boat I am working on, after I pressure wash it, for instance. However, if I am doing something inside the house, or I just really don’t feel like moving the shop vac, I thought it would be a great idea to have a faucet and hose connection also at the bottom so I could alternately vacuum water out and then open the drain connected to a hose and let it run to wherever I wanted it to run and not be under foot. Also, if I happened to be using it inside, the hose would drain it outside and make the water pick up very easy.
Action: I bought a faucet, like one that would be installed on the outside of the house, and put it into the bottom of my large shop vac. This worked so well that I bought another valve that is more like a gate valve, that opens and closes quickly without it having to be unscrewed. Since I installed the faucet in the large shop vac, I subsequently purchased a ¾” pipe tap. On the small shop vac, I used that to thread the plastic base and insert the faucet. I then sealed around the inside with Goop. On all of my hose connections I have quick disconnect connectors. I installed one of those on the threaded portion of the faucet, so now I can easily attach a hose should I need it.
Result: It works great!
When idea was conceived: May 2014 – large one and 2/15/15 – small one
How much time it took to develop: First one: 1 hour. Second one: 30 minutes
How much money it took to develop: $11 for each faucet
Current status: In use for small one. Larger one replaced and faucet not installed.
